pass boolean value from command button to PID module

hagouda — Tue, 05 Nov 2024 16:10:46 GMT

Deal gents can controle

I got a request from operation to create command button on one graph which selects between two PID modules . The operator can only control one of them. I've created the command button and change its caption each time the operators click. I need a way to write a value in the selected module to enable operator control and not this value in the other non selected pid to prevent any access to it

my question is what is the VB command to write in any module.parameter in Deltav?

I have Deltav 14.31

Deltav operate

I do not prefer to use global variable . I just need the opposite function to datalink function.

Thanks

Dear All

I have one pro , 2 engineer, 14 ows, one HIST

ows 1, ows 7, ows 13 do not open control studio giving error Access denied as shown in photo

Note that these stations also could not access online database when using 'DVoperate in configuration mode:

provided that :

1- service password is correct and confirmed

2- when run deltav workstation configuration program it fails to complete and the only way to rerun the OWS is using regall /register command

NOTE : : SECOND PHOTO IS WHAT I GOT AFTER RUNNING DVWORKSTATION CONFIGURATION UTILITY

SO PLEASE ADVISE

THANKS

Dear Andre

Thanks for following up. Kindly not that Unfortunately my GSC was expired

I created a new account on user manger and granted all groups and keys
I ran workstation configuration utility
It sticked on last phase "registration Dv password " as shown
Pls note that pwd is right no way to enter wrong pwd
Then the machine lose everything and DV does start after restarting
Then I ran regall /register
It asked for pwd
Then it restart
Workspace run mode works well
Download from proplus is OK
All operation activities is OK
Dvcs gives access denied
Workspace configuration mode cannot access online database
Meanwhile I cannot reinstall DV and hot fixes as I don't have GSC
YOUR SUGGESTIONS/SUPPORT S HIGHLY APPRECIATED

RE: OWS can not open control studio ang gives Access Denied

Andre Dicaire — Tue, 21 May 2024 16:09:21 GMT

When Control Studio is launched from the start menu, it makes a connection to the database, even if no module is defined.

Below is a connection with user <none> when I launch Control Studio from the Windows Menu and I have not logged into DeltaV.

Below shows my Control Studio Session when I have logged onto DeltaV with account "AD".

What this tells us is that your current Windows User credentials are used to open Control Studio on the workstation. That is, the Windows Login user must have windows access to the Control Studio (CS.EXE) program. This user must be granted DeltaV access rights to the DeltaV folders, which is done by creating the user through DeltaV User Manager and selecting that a Windows user be created with the same NAME as the DeltaV User.

Troubleshooting through an open forum is always going to be a slow and painful process as we offer suggestions that don't pan out because we don't know what you don't tell us. And telling an open forum about your user security and computer node names is a security risk. So be careful what you share.

At this point, it sounds like a windows security issue, since launching Control Studio does not require a DeltaV logon, just the windows logon, which grants you file access on that computer. When Control Studio launches, it connects to the database and passes the DeltaV user to the database, which determines your DeltaV Privileges such as Can Configure and other database access keys. With out those keys, Control Studio will be in View Only mode.

You can logon to a DeltaV workstation with any windows account that Windows recognizes, including local accounts and Domain Accounts. If the Account is not in the DeltaV group, then launching any DeltaV program will have an Access Denied message. When you create the DeltaV user, you have a choice to link it to a specific version of the user: A Local account, a Domain Account, or any user with that name. The computer may recognize a local or domain user and authenticate it. But if it does not belong to the DeltaV group on that workstation, you can't launch programs.

So start by checking that the user is a valid DeltaV account by confirming how it is configured (Local/Domain) and that it is in the requisite security group.

That other possibility is that the DeltaV programs have had their security altered such that they do not allow DeltaV users to access them, that is, the DeltaV group has been removed from the program's access group.

If you cannot identify any issue relating to user security or program access rights, I recommend you Uninstall DeltaV and all other programs. Reboot and start over with a clean DeltaV install, ensuring you properly join the Domain. That would include Mcaffee and any other programs, support or not. This is the "I give up " strategy and will not identify the root problem, but it should restore all user and program rights and resolve the issue.

I still strongly recommend you log a call with the GSC so that you can discuss sensitive user security settings with a limited audience.

Dear Neil

Kindly note that I have tried all your suggestions and still same issue DVCS don't open giving ACCESS DENIED without any errors generated on eventvwr for windows

As attached

Also note I have error also when using Dv operate in configuration mode it can not access online DB

also i noted today. That when try to regall /register it works till the end then it asks for DV admin service PWD I input it then it askes for reboot with oit any results

i confirm that this is fhe only pwd used all over the system

I double checked with the guy who installed the system and today I tried on another WORKING OWS

If you enter any other pwd the system stops refund the wrong pwd and won't complete until entering the right pwd

Thanks for your Time and support

RE: OWS can not open control studio ang gives Access Denied

Neil Castro — Mon, 20 May 2024 00:48:45 GMT

Dear Hossam,

This means there is an issue with the Control Studio application as long as the DeltaV and Windows user who is logged in is authorized to open Control Studio. When this application is open in the Windows start menu it does not connect to the database but when it is launched from a faceplate it connects to the database because it needs to open the module that the faceplate is referencing.

I think a normal Control Studio will always open if it is launched from Windows start menu as long as the user is authorized. You may try to export, delete, and reimporting the OWS node with issue then do a total download but there is a low possibility that this will resolve it.

You may want to check with IT if they did any restrictions to the OWS or if they did any blacklisting/whitelisting. Check the executable file (C:\DeltaV\bin\dvcs.exe) security that users are allowed to execute or you may compare it with a working station.

I could not think of any local files or settings in Control Studio that can be reset or recreated. In case you have time you may want to do further diagnostics by opening Control Studio in Windows start menu then note of the time when the access denied error comes up. Open Windows even logs (Application, Security, and System) and see if there are errors/warnings that correspond with the access denied error.

RE: OWS can not open control studio ang gives Access Denied

hagouda — Thu, 16 May 2024 04:14:25 GMT

Dear Neil
Actually I tried to open control studio from windows start menu , from faceplate same results
Access Denied
Does this mean that the problem is in the application it self or the application connects at startup with proplus to test license?
As on other machines with operator license control studio says during opening that "due to license for this machine control studio will open in view only." Then it opens
The above behaviour is on all working OWS

≈============≈=

***just a question, Does control studio connects by default to online database/Pro plus during lunching ? Or just check the license on the local machine?

If so and you know these local files . Can these files be copied from other machine.

or can we unassigned the license then reassign again and download?

If so pls share procedure for doing this

Thanks

Neil Castro — Thu, 16 May 2024 00:40:18 GMT

Dear Hossam,

Have you tried launching Control Studio from the Windows start menu? It should launch successfully without an open module. This would test if there is an issue with the Control Studio application installed in the machine.

In case Control Studio opens, try to open a module from this Control Studio.

RE: OWS can not open control studio ang gives Access Denied

hagouda — Wed, 15 May 2024 12:20:43 GMT

Dear All
Unfortunately I have tried all solutions followup all your recommendations/ steps still getting same issue moreover I compared services between one malfunctioning machine and other working well both have same service status.
Firewall and windows defender are disabled in both machines

I am using Emerson smart switches and unmanaged

Network is OK all other machines are working well and these machines works well with Deltav operators run mode getting live data, alarm,..faceplate, open close valves....

Thanks for your response
Hossam

RE: OWS can not open control studio ang gives Access Denied

Neil Castro — Wed, 15 May 2024 00:28:57 GMT

Check if DeltaV network is set properly.

On one of the stations with issue try to restart the machine one more time and do a total download of the station from the PRO+. Check if you can open a module in Control Studio on-line mode.

In case the issue still exist, disable or physically disconnect all network connections except the DeltaV Primary, this will force all communications to the DeltaV Primary NIC. Do a ping to 10.4.0.6 (PRO+), in case the ping fails then you would need to troubleshoot your network connection to the PRO+.

In case ping is successful try to open a module in Control Studio on-line mode and see if it opens. In case it opens then you may need to check the NIC binding order of the machine if it is as per Emerson documentation. In case Control Studio fails to open then it can be a security or firewall issue, you may want to check the user access and if the machine belongs to the same domain/workgroup as the PRO+. Check if Windows firewall is disabled on the station. Verify that you are using unmanaged switches or DeltaV smart switches and check if there are recent changes to the DeltaV network that you are not aware of.

RE: OWS can not open control studio ang gives Access Denied

Andre Dicaire — Tue, 14 May 2024 14:13:48 GMT

OK, you've eliminated the deltavadmin password.

DeltaV core communications explicitly uses the DeltaV primary and secondary networks. Some higher level apps like Control Studio use the binding order to select the NIC and if different on both ends, this can cause issues, though I don't know if this symptom is consistent with that.

What is the difference between these stations that don't work and those that do? Network connections are the same? Can you ping the Primary and secondary addresses? (networks are not crossed) Different computer models?

I'd recommend you log a call with the GSC as they can mine the known issues and similar customer calls and resolutions. I'm probably wasting your time with guesses.

RE: OWS can not open control studio ang gives Access Denied

hagouda — Tue, 14 May 2024 09:13:30 GMT

Thanks for your response. Kindly find what I did as follows

1- I know Deltav admin password

2- on one of the working good machines I changed the pwd using servpwd.exe to change the password and rebooted but still control studio is working fine so the issue is not only pwd

3- on the pro I used servpwd.exe to confirm that I have the right pwd

4- on one mal function ows I used servpwd to change the pwd using the one I know for pro then rebooted but still control studio gives access denied

5- according to help I need to register services after changing pwd so I use regall /register , it works fine till the last point then it askes for Deltav admin PWD

and it stops until I put the right pwd.

6- after all still same problem

Thanks

RE: OWS can not open control studio ang gives Access Denied

Andre Dicaire — Mon, 13 May 2024 14:15:14 GMT

Access Denied would likely be caused by not having the DeltaVAdmin user password properly set, preventing those stations from being able to access the database on the Pro Plus. This password is normally set when running Workstation Configuration. It can be reset running servepwd.exe, which applies the new password to all the services that use the DeltaVAdmin account. Altering this password manually on a station will not resolve this issue.

If you do not know the current DeltaVadmin password for the system, you will have to reset all machines to a known password, starting on the pro plus, and work your way out from there.

Suggestion: If you do not know the current DeltaVAdmin password, you could confirm that the password is the issue. On one of the machines that is working, change the DeltaVAdmin password thus break this machine's access to the database. Then you can observe if the issue presents in the same way. Then you know that you have to reset the password and that it will fix it. But you really need to know this password anyway.

If you know it, try setting it on one of the broken machines.

RE: deleted files after download

Dear Neil

We actually disable auto update for all machines a we have some issues related to grph.

I enabled auto update for setup data and devices then downloaded this OWS the files were recreated as you mentioned.

Thanks a lot for your support

deleted files after download

hagouda — Wed, 07 Feb 2024 16:17:46 GMT

Dear All

I have a new issue whenever i download my engineering workatation some files on folder D:\Dvdata\download are deleted and are not recreated

this impacts module search in deltav operate run mode

Also when i tried to run Deltav workstation utility the machine continue and after restart it losses communication with Deltav despite it is a part of the domain

and the only way to fix this issue is to restore from image which have the download issue.

the above issue is repeated foe 2 ows

we run ver 14.3.1 lts

thanks

RE: deleted files after download

Neil Castro — Tue, 13 Feb 2024 13:16:50 GMT

It appears auto-update is disabled on the station.

At least enable Setup Data and Device Files on the station as shown in the below screenshot. Click on Set button then try to download the station again from the PRO+.

RE: deleted files after download

hagouda — Tue, 13 Feb 2024 08:16:01 GMT

Dear Neil

Kindly note that I have deleted all files in \yellowpages\download folder then I downloaded the machine from pro+

Still only 16 files are there in Deltav\Dvdata\download folder while 3 files in yellowpages\download folder

Also not that when I Download setup data or changed setup data or last good known files are not deleted

they are deleted only when download operator workstation

Thanks for support

RE: deleted files after download

Neil Castro — Tue, 13 Feb 2024 03:13:42 GMT

You may have some corrupted files under YellowPages\Download folder. The download does not automatically copy files to the "download" folder when the YellowPages counterpart file with .Z extension is corrupted.

May want to try the following on one of the non-critical stations. Do NOT do this on the PRO+.

1. Delete the content of "D:\DeltaV\DVData\YellowPages\Download". You may want to copy the "YellowPages\Download" folder to another location (example the Desktop) for backup. The folder should look like the following but in my system it automatically recreated the files. Do not worry if the files reappear after the deletion.

2. Perform a full download of the station from the PRO+.

RE: deleted files after download

hagouda — Mon, 12 Feb 2024 15:58:15 GMT

first of all thanks for your reply

1- kindly note that no nodes needs download

2- our pro+ is a primary domain controller while one history server act as secondary controller

3- All machines are synchronized with pro+ ( time is identical )

pro+ d:\Deltav\dvdata\download\

DCS-OWS-10 D:\Deltav\Dvdata\download before download

DCS-OWS-10 D:\deltav\Dvdata\download

I need to copy download folder contents either from pro+ or any other workstation to this machine to work well

Finally

No virus found

Updated antivirus

Thanks for support

RE: deleted files after download

Neil Castro — Mon, 12 Feb 2024 06:37:59 GMT

Check if the PRO+ needs a download or has a download flag.

Is your PRO+ a domain controller or do you have an independent domain controller?

Check the time of the domain controller and see if all workstations are in sync.

You may also post in this forum a screenshot of the content of the download folder before and after the download. May also want to include a screenshot of the download folder of the PRO+.

Check if you have a virus in the system that maybe causing this unwanted deletion.

RE: self delete graphics

ha nguyen — Tue, 06 Feb 2024 15:21:08 GMT

Just a quick note to share what we did to solve the problem. Hope this will help someone with a similar situation.
At the problematic OWS, we opened the graphic file to be added using DeltaV Operate Configure, then saved it to the Pic folder of the OWS.

Best.

self delete graphics

hagouda — Sun, 28 Mar 2021 18:14:00 GMT

Dear All

on PIC folder I deleted some files called group3000_01, group3000_02

Then I created a new ones with the same name

but they are auto deleted from the folder.

on other words

the system automatically deletes any new files has a previously deleted name

my ver is 14.2

Also I am disable auto update for displays

thanks

RE: self delete graphics

ha nguyen — Sat, 03 Feb 2024 19:32:40 GMT

Hello,

We are running into an exact situation here and may I ask if there is now a reliable, consistent procedure to remove/delete old graphics and replace them with new ones of the same names?

We followed the Deleting and Restoring Graphics method stated in Book-Online including deleting old graphic files using DeltaV Operate Configure and emptying the DeltaV Recycle Bin. Yet, one of our OWS absolutely refuses to accept one new graphic file (of the same name) even though another OWS accepted it fine. The ProPlus also was able to have the new graphic files. We had also tried manually copying using Windows Explore with the Auto-Update Service disabled.

Your advices are appreciated.

Hagouda: Would you please elaborate on what you did here to make it work?

"When I copied .grf.z file to yellow pages of one OWS then copy thisgroup3000_07.grf file it was not auto-deleted and every thing was ok
amazing...!"

Streched daynamos

hagouda — Sun, 07 Jan 2024 12:47:27 GMT

Dear All

Kindly note that I have Deltav for more than three and half years. Recently we upgraded the release to 14.3.1 but unfortunately we got some issue with some dynamos which are screeched when the operator moves between two or three Graphic quickly from operator keyboard using key macro in user file.

The combination which makes error is CTRL+shift + any key

any other combination does not make any error

I simulate the operator keyboard by using standard keyboard and press ctrl +shift + (A to Z) got same error

Also we have some keys built-in toolbar if you press ctrl + Shift and keep moving between two grph quickly

you will get same error as shown in th next pics

Thanks

replacing failed ows

hagouda — Wed, 20 Dec 2023 17:24:12 GMT

Dear All

i have recently installed deltav 14.31 on DCS system porplus as domain and 12 operator work stations and one engineering

recently one ows hdd failed

i am unable to reinstall system from beginning as I am out of gradian

Do any one have a solution for this

considering if I got image from one OWS the restore on another new machine then use Deltav workstation configuration tool to rename the the domain recognizes this and blocks the original one from log on

which means i ll lose the running one and could not reconnect it to the domain

any help will be appreciated

Thanks
