I had a problem with Pro Plus. Services suddenly stopped and wouldn't start for a while (Operation Run, Explorer, Trends, Administration). "A problem caused the program to stop working correctly. Please close the programm." At the time, I had no similar problems on terminal servers or workstations. I was having trouble downloading files, and the download kept getting interrupted. "error code 4, OSS_TIMEOUT" All network connections are OK After closing all open services and a few hours later, everything started working again (the download option appeared earlier).DeltaVhttps://emersonexchange365.com/services/b/weblog/posts/managing-change-in-process-control-lessons-from-greg-mcmillanFri, 15 May 2026 13:00:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:8293af3d-a733-4437-8bb4-80113cbe4cb1Jim CahillIn this seminar, Process Automation Hall of Fame member Greg McMillan delivers a masterclass on the foundational concepts that drive process control improvement.

A follow-up question came up regarding redundancy switchover. We are able to do a forced switchover but cannot switchover within diagnostics with the Proplus connected to the primary port. Diagnostics shows bad redundancy due to no primary ACN communication, but always and only the standby controller. When a forced switchover is done the bad communication is always with whichever controller is the standby. The Active controller primary connection remains healthy. Is this expected behavior for a standby SIS architecture in V12? Will v15 make it possible to switchover within diagnostics?https://emersonexchange365.com/services/f/services-forum/11381/standalone-sis-v12/25186Fri, 16 Jan 2026 16:08:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:094087fc-765d-4417-99ba-6c654b3e10e8Andre DicaireYes, this is a proven architecture. Both ACN DeltaV traffic and ModbusTCP traffic co-exist on the same physical port. The ACN RJ45 ports of the SZ controller also serve as the Modbus ports by design. The SZ ethernet ports are configured with two IP addresses on different subnet masks. A switch will locate the connected ports for the Pro Plus and ModbusTCP client and communications will be passed accordingly. Depending on your cybersecurity risk tolerance and network design, you may choose to add a firewall to limit traffic flow, including keeping DeltaV ACN traffic on the DeltaV SIS side, and allow only valid ModbusTCP traffic between the SZ and the Client. As of v13, the Modbus TCP connection can be redundant, with primary defined typically to align with DeltaV ACN usage, that is primary network on the left, Secondary on the right.https://emersonexchange365.com/services/f/services-forum/11381/standalone-sis-v12/25185Fri, 16 Jan 2026 13:47:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:000f7a58-27b8-40ee-a077-4aab9b714842Russell E SmithI found a DeltaV SIS Standalone Whitepaper dated June 2020. The existing Standalone SIS system has been running for nearly 10 years. The issue has been that Modbus communication connected to the secondary ACN/Modbus port frequently locks up and that data goes stale. A redundancy switchover has been the recovery work around. The Proplus is a Toughbook laptop and may be temporarily connected to the Primary port for configuration, commissioning, flashing, downloading, etc. In V12 Modbus on SZ controller was simplex and must be connected to the secondary port. It is my understanding that Modbus ports are redundant since v13. We are trying to find out if the Standalone SIS with the redundant Modbus communication in v15 is a proven architecture. The white paper shows the top ports of the isolated ethernet parts are Redundant Modbus/TCP. In BOL show them as both ACN and Modbus. Hopefully this information helps to clarify my question - Can both Modbus ports be enabled for redundant Modbus while still being able to connect the Proplus? Or should only the secondary Modbus port be enabled for a Standalone SIS node, thus negating any opportunity to utilize the Modbus redundancy feature in the later versions?https://emersonexchange365.com/services/f/services-forum/11381/standalone-sis-v12/25184Fri, 16 Jan 2026 08:14:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:3000504e-2d0b-4cc0-b5fb-f25ae9b6b090Mark FloresI haven't tried this setup. Typically, if this is not publish on BOL or KBA, this is not supported. Why do you want to connect your old Proplus to the MODBUS network if i may ask?https://emersonexchange365.com/services/f/services-forum/11381/standalone-sis-v12Wed, 14 Jan 2026 16:09:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:06834212-a861-4104-bb4a-501ca8cbee4fRussell E SmithIs there any information on how to connect the temporary Proplus to the Primary Modbus port IP address? We are unable to find any specific information in BOL or Guardian. It obviously connected years ago when the system was first deployed because the SZ controllers were commissioned at that time. The temporary Proplus IP address is set to 10.4.0.6, 255.255.2.0. The Modbus address is set to 167.151.x.x, 255.255.255.0. The system still is V12. Should it still be possible to connect the temporary Proplus to the Primary port since the Modbus address was changed. In v12 there is no way to set the primary and secondary Modbus port separately. An upgrade to 15 is being considered. Is the connection method different with v13 and up?https://emersonexchange365.com/services/f/services-forum/11330/deltav-reporter-configurationMon, 01 Sep 2025 10:09:00 GMTcd40bb2b-3d49-4868-939d-417119b40291:e27eb38b-aeed-4bbd-aa22-00c0a741c02aMAITY_TRIDIPDear All, I a, using DeltaV 10.3.5 and installed MIcrosoft Excel 2007 in my ProPlus station.

The heart of a desuperheater is its spray nozzle, but these nozzles are often installed and forgotten until they fail, resulting in expensive repairs and downtime. Our article in the May 2025 issue of Automation.com Monthly , titled “How Desuperheater Nozzle Testing Prevents or Predicts Failures,” describes how to create a cost-effective nozzle testing program that can pay for itself many times over. A critical and sensitive process Many steam process loops, such as those found in typical combined cycle power plants, use desuperheaters to lower steam temperatures to safe levels. The desuperheating process is highly sensitive, requiring just the right amount of water to be atomized into a fine mist. An analysis of combined cycle outages shows that most forced outages result from damage to the heat recovery steam generator (HRSG) coils as these usually see the highest temperatures and most difficult process conditions. A common cause of these failures is desuperheaters which either add too little water, too much water, or fail to atomize the water adequately. HRSG damage occurs quickly and has significant repercussions, costing $2,600,000 USD and four days of downtime to repair on average. Figure 1. Over temperature damage in pipes from poorly functioning desuperheaters will result in significant pipe and equipment damage, requiring extended outages for repairs. Nozzle problems Desuperheater nozzles are designed to distribute a uniform stream of atomized water droplets, but over time they may degrade or plug, disrupting the intended spray pattern and creating water streams that damage piping. Figure 2. Nozzle plugging or damage can restrict flow. Clogged nozzles can also severely restrict flow, limiting the desuperheater’s ability to control temperature. In some cases, erosion can destroy the desuperheater head, allowing water to bypass the nozzle completely, causing catastrophic damage. A simple solution Routine inspection and testing of desuperheater nozzles is a straightforward and effective way to avoid the problems described above. Many process plants contract with accredited service providers to perform nozzle flow testing and repairs, either on-site or in local facilities. Implementing a routine nozzle maintenance program is inexpensive compared to the cost of even a single HRSG outage. Figure 3. Accredited nozzle repair facilities can bring nozzle flow test stands, like the one pictured here, to the site to check all the desuperheaters in a unit during an outage. Flow testing proves nozzle functionality, and any issues can be addressed quickly. The cost of nozzle neglect One power plant noticed the valve responsible for controlling the spraywater to the desuperheater was running nearly fully closed, yet the temperature downstream of the desuperheater was being measured well below specification. An Emerson Accredited Service Provider suggested the unit be taken out of service and immediately flow tested, but the plant continued to run. Three weeks later, a weld joint cracked on the downstream piping, causing a 10-day outage and costing the plant $250,000, far more than the $13,000 it would have cost to flow test the nozzles. Following that incident, the plant discovered that six more of their ten desuperheaters required repairs and/or replacement nozzles. The plant instituted a regular nozzle maintenance routine, preventing future failures and dramatically improving desuperheater performance. Service providers simplify nozzle testing Like all mission-critical devices, desuperheater nozzles should be regularly tested and maintained to prevent expensive outages and repairs. Many process plants find it best to contract this task to accredited service providers as they have the equipment and expertise to perform nozzle testing, repairs, and replacements.

I installed DeltaV 14.3.1 FP1 on a new workstation to be an "Oper-station" (Precison 5860), but when I try to open Operate (run or config mode), it closes before the loading percentage bar appears and does not display any errors. I have already installed several DeltaV workstations, but this problem has never occurred. Have you ever encountered this?
