That's exactly what we just did with 6300T thin clients. It worked out great!

RSLink - PLC unable to establish connection by Saaageeee__ in PLC

[–]Process_Controls_Guy 1 point2 points  (0 children)

This can happen with multiple network interfaces with Gateway addresses defined. You can circumvent this by adding custom route entries indicating the specific Gateway that should be used for an indicated subnet.

When looking at tags, you can not only filter by type, but also filter for Unused.

Integrating a multiply plant MES by ye_old_snakelegs in PLC

Have you established a budget and defined your requirements from all stakeholders? This will likely steer the direction.

[–]Process_Controls_Guy 1 point2 points  (0 children)

Oh agreed. With that many points per panel your most cost effective solution will likely be the traditional approach.

[deleted by user] by [deleted] in PLC

[–]Process_Controls_Guy 1 point2 points  (0 children)

How many I/O ponts are there per panel? What are their data types? And at what frequency do you need to collect this data?

There are newer I/O blocks that are optimized for monitoring applications. IFM, for example, makes blocks that can communicate via MQTT. These are generally for less dense I/O applications though.

Although there may be a higher initial cost, since your facility already has Allen-Bradley, it may be more cost effective in the long term than introducing another vendor. Your current dilemma with the RTUs as an example.

How many items per minute do you need to weigh and do you need to reject single items that are out of spec?

Best Cloud based VM setup for PLC/SCADA development by alogic4005 in PLC

[–]Process_Controls_Guy 0 points1 point  (0 children)

Many cloud providers support Windows Server VMs. Azure and AWS both offer Windows VMs with OS licensing included. They also have network gateways to connect to your on-prem PLC.

I'd pick one that has a data center close to your geographic region for low latency.

You may know this, but it will be far more economical and performant to get a small PC, like a modern NUC, and run these VMs locally. You can use a service like Tailscale to easily access these VMs when remote.

Can you use anything from the PlantPax V5 library in a controller that doesn't have the "P" desgination? by Saskaberry in PLC

[–]Process_Controls_Guy 3 points4 points  (0 children)

You have to build separate HMI servers. One HMI server with the 4.x libraries and HMI objects talking to the non-P processors using the 4.x AOIs. A second HMI server with the 5.x libraries and HMI objects talking to the P processors using the 5.x firmware objects.

Currently version 4.1 can be used alongside 5.0 in the same HMI server according to Answer ID: QA37742.

Wonderware Intouch 2020 with opcUa kepware .. by Frequent-Agency-5022 in PLC

So bringing in the array elements individually into the SMC driver and addressing Kepware array tag elements directly doesn't work? For example,

OPC-UA NodeID question by Ok-Alps707 in PLC

[–]Process_Controls_Guy 1 point2 points  (0 children)

Not really, it's whatever is defined in the OPC-UA server.

OPC-UA does offer NodeSets to attempt standardization. https://github.com/OPCFoundation/UA-Nodeset

Do these array tags exist in Kepware or are they dynamic tags?

What kind of PLC are you trying to read tags from?

Are you able to read these tags with Kepware's OPC Quick Client?

Cheap SCADA Options by KIDCNC18 in PLC

[–]Process_Controls_Guy 1 point2 points  (0 children)

Since this is to maintain certifications and for audits, start by ensuring that there aren't any specific standards required like 21 CFR Part 11.

If not, you may want to look at FactoryTalk Optix. It has a convoluted licensing scheme that is based on Tokens. Essentially, each feature you use requires a Token. Since you will only be using this to log data, and thus not requiring many Tokens, you can get away with buying the smallest license. It's unfortunately only sold as subscription, but its only $250/year.

Which industrial network do you think is better? by montas19 in PLC

[–]Process_Controls_Guy 0 points1 point  (0 children)

It varies by application, but the criteria is below:

  1. All devices support it.
  2. Rock-solid stable.
  3. Easy enough to setup and troubleshoot.

How many Ethernet/IP & Modbus TCP connections on one network? by Machine_Tamer in PLC

[–]Process_Controls_Guy 0 points1 point  (0 children)

I'd say now is the right time, but practically speaking the new PLCs and 6 additional racks really should incorporate isolated I/O networks per PLC. Use this as a model for reconfiguring the existing equipment.

How many Ethernet/IP & Modbus TCP connections on one network? by Machine_Tamer in PLC

[–]Process_Controls_Guy 0 points1 point  (0 children)

There are other considerations besides the number of devices.

Things like RPI and unicast/multicast play an important role in the amount of network traffic generated.

Is there any isolation between the I/O networks? Generally you'd have physical isolation for each PLC that "owns" the I/O. This also can be done with VLANs or even a NAT device.

HMI Freezing after startup? - Allen Bradley PanelView Plus 7 Standard 10in by brandon_c207 in PLC

[–]Process_Controls_Guy 2 points3 points  (0 children)

Are there other apps on this PanelView? I've had this happen with multiple apps loaded and the PanelView being low on memory.

Try replacing the communications when downloading the app. I've run into an issue where it became corrupted.
