NUMATICS G3 ProfiNET node webserver in Win10

Stanislav Mares — Thu, 02 Dec 2021 11:29:12 GMT

Hello,

please be so kind and help me. I have problem with NUMATICS G3 ProfiNET node webserver in Win10.

It is not possible to connect it. A message is displayed - the page cannot be displayed.

I think the problem is in Win10 because in Win7 it works properly and the node G3 ProfiNET communicates with the laptop.

Is there any settings in Win10?

Thank you for your help

Best regards

Stanislav

Ex pneumatic actuators II 2G Ex h IIB T4 Gb

Stanislav Mares — Sun, 01 Dec 2019 20:19:35 GMT

For Ex (ATEX) pneumatic actuators (non electrical devices) there is a "new" type of protection - h, Ex II 2G Ex h IIB T4 Gb.
Is this some news?
Can you please provide more information about this?
Tank you very much
Best regards
Stanislav Mares

Hello Stephan,
thank you for answer.
It is the same / similar like c - safe construction, b - monitoring of ignition sources, k - immersion (liquid) protection?
Best regards

Hello Stanislav,
within the ATEX directive, the designation ‘h’ for non-electrical devices has existed since around 2016. Manufacturers had some transition time available (until October 2019) to issue/update their Declarations of Conformity. The Protection Principle "EX h" makes reference to "mechanical equipment".

Functional Pneumatic Safety in Machine Automation

Tom Voth — Tue, 25 Sep 2018 15:17:48 GMT

Safety is a hot topic and ISO 13849-1 / 13849-2 has become the primary standard driving pneumatic functional safety within the machine automation space. Functional safety provides machine builders and users the freedom to satisfy the requirements of safety standards in various ways. The traditional way to render machinery safe is to release energy. This may not always be the best or most efficient solution, as it does not always prevent unwanted motion during the “energy releasing” phase or allow a predefined safety position to be achieved.

The move to functional safety in pneumatic circuits has great potential to improve machine efficiency. Historically, the go-to solution for safety in pneumatic equipment was to employ a dump valve that releases all pressure. This solution often negatively affects machine efficiency, especially in situations with frequent operator intervention such as load/unload stations. Releasing pneumatic energy exhausts compressed air which must be recharged upon start-up. This process costs money and decreases machine cycle time.

There are three basic safety functions in pneumatic circuits – release of energy, return home, and stop/inhibit motion. Depending on a machine’s pneumatic content, any of these safety functions could be the most efficient and safest method.

The traditional dump valve / release energy solution is the best solution for some applications. In many instances, however, it would be more efficient to stop/inhibit motion, return home or use some combination of the safety functions tailored to the specific safety requirements of the equipment. It is sometimes also more efficient to inhibit specific portions of a machine while the rest of the machine operates normally.

ASCO’s Zoned Safety manifold allows users to define and setup multiple, independent safety functions in up to 3 discrete safety zones all within one valve manifold. This solution can achieve up to Category 3, PLd, as defined by the ISO 13849 Functional Safety specification. This basically means that each zone in the manifold can provide a custom redundant functional safety solution with appropriate diagnostic coverage (DC). This is a suitable solution for most manual load/unload stations and a wide variety of other industrial applications.

Using ASCO’s Zoned Safety concept, it is possible to customize a solution that is both safe AND efficient:

Streamline plumbing by working safety into an existing pneumatic manifold
Incorporate up to 3 safety zones into one valve manifold and setup non-safety zone valves on the same manifold for those functions that must not shut-off (e.g. vacuum holding force)
Provide multiple and independent safety functions as needed
Reduce compressed air usage
Minimize restart times to increase throughput
Is compatible with various fieldbus protocols

How to Select a Machine Automation Fieldbus

Steven Fales — Fri, 21 Sep 2018 13:50:37 GMT

Fieldbus is a common industrial term with very different meanings depending on what industry you work in. In process or formula-based manufacturing, fieldbus commonly refers to FoundationFieldbus or HART connecting to a distributed control system (DCS). In discrete or individual unit manufacturing, fieldbus typically indicates usage of PROFINET, PROFIBUS DP, EtherNet/IP, EtherCAT or DeviceNet industrial networks connecting to programmable logic controllers (PLC). Today we’re going to focus on industrial network architecture within the discrete manufacturing or machine automation space.

In a white paper titled “Five Critical Factors for Selecting Fieldbus Valve Manifolds” Enrico De Carolis discusses how machine automation fieldbus enables the integration of communication interfaces to pneumatic valve manifolds with input/output (I/O) capabilities. This allows PLCs to more efficiently control valves and to channel I/O data from sensors, lights, relays, or other I/O devices via various industrial networks. The resulting integrated control packages can also be optimized to allow diagnostic and prognostic benefits not previously available.

Fieldbus valve manifolds find wide utility in packaging, automotive/tire, and material handling applications, as well as in the pharmaceutical, chemical, water, and wastewater industries. They are specified for purchase by controls engineers at original equipment manufacturers (OEMs) who design and develop industrial automation solutions — as well as by end users in relevant industries.

It’s beneficial for engineers, specifiers, and buyers to consider the following five crucial factors before selecting pneumatic fieldbus valve manifolds for machine automation applications:

Commissioning – Time, difficulty and costs add up quickly when commissioning the valve manifold: mounting it on its specified automated machine; connecting network and I/O cables, power, and compressed-air supplies; configuring its parameters; and testing it.
Distribution – Fieldbus nodes that are capable of handling both valves and I/O as well as the mutual distribution of I/O and valve manifold functionality around a given machine lowers network hardware investment, saves time, and decrease the number of nodes on the network.
Modularity – Conventional nonmodular designs force the user to dismantle the entire assembly to get access, dismount the malfunctioning module, replace it, and then reassemble the whole fieldbus manifold or system.
Diagnostics – Easy access to diagnostic indicators is critical in locating a problem and identifying the cause to get the machine up and running quickly.
Recovery – The ability for a manifold to automatically recognize a replacement communication and I/O module and reload all settings, configuration parameters, and other pertinent information can reduce downtime considerably.

ASCO G3 Fieldbus was designed with the five previously outlined crucial factors at its core and as a result can save installation, maintenance, and repair time as well as reduce cost. Commissioning time is reduced by embedded graphic displays that enable quick setup. Valve manifolds can support up to 16 I/O Modules and 128 valve solenoid coils, which can then be distributed for up to 17 total manifolds per communication node. A novel “clip” design allows easy module removal/replacement without dismantling the manifold. Diagnostics are available in plain text on the embedded graphic display and via the integrated web server. Finally, the Auto Recovery Module (ARM) protects configuration information to enable faster recovery during a critical failure.
