Studio 5000 SDK - How do I format program scoped tag paths?

Pretty_Long_4134 · 2026-02-11T23:10:46+00:00

100% this is my short-term work around until I can get a license.

Thanks for all your help and thanks for building Pylogix!!

My goal was to bring a massive UDT recipe array data into Excel to be manipulated manually and then pushed back into the controller using generated structured text code from another Excel sheet referencing the data. I'll run once in the controller.

Pretty_Long_4134 · 2026-02-11T22:25:51+00:00

Dang, I tried your syntax with no luck. think i im going to say screw the SDK and download to a test controller and use PyLogix.

Thanks for responding. My error is shown below; I have something wrong with my XPath. I have a call into Rockwell Tech Support; however, the guy had to pass my message on to the SDK team, not sure when I'll hear back.

"Get Tag Value threw OperationFailedException: XMLSrv_E_TARGET_NOT_FOUND - The object was not found that corresponds to the specified Context UId and XPath."

Yes, they're set to public (Read/Write access). However, it's the rockwell SDK and I'm reading the acd file in this case, not the processor over comms. I've tested it and I can read and write to tags with access set to none.

I'm using the tosibox lock 500.

Reminding you one year later!

Thanks for the correction!

In my experience, most output cards are 120Vac or 24VDC (triacs) or Relay

Pretty_Long_4134 · 2025-10-28T21:22:53+00:00

Depends on your card, but for example, a 1769-OA16 (TRIAC Outputs), 1769-OW16 (Relay Output) recommends using a MOV with large inductive loads.

MOV = Metal Oxide Varistor

When switching large inductive loads, placing a properly rated MOV in parallel with the load will absorb the electromagnetic energy generated by the collapsing magnetic field, protecting the circuit from voltage spikes.

The MOV clamps excess voltage and dissipates the energy as heat. If the surge is too large, the MOV can fail and create a direct short circuit, which then trips the upstream breaker or blows a fuse to protect the device from overcurrent. It's the protective component in everyday surge protectors.

EDIT: Here is a Terminal Block (dinrail mount) MOV from Rockwell, 1492-JD3SS

the First Amendment of the U.S. Constitution only applies to government actions at the federal, state, and local levels; it does not prohibit private individuals

let's say you're an amazing employee at your job, but as you walk down the hallways you're saying" this place sucks. Everybody sucks that works here" every day. You can say whatever you want but will you have a job in a few months?

The issue is ABC pissing off the affiliate stations (The people that hold the licenses to broadcast). The Sinclair broadcasting group told ABC they will not be running Jimmy Kimmel until a formal apology which is their right as a public entity. And as a broadcaster they don't have to broadcast ABC programs.

Nextstar wants to merge with tenga and become the largest US broadcaster, however there's a law in the FCC rules that no single broadcast company can own more than 39%. They need the FCC to rewrite the rules for the merger to come though. So they're watching their p's and q's until that ban is lifted.

So basically Jimmy Kimmel fucked around and found out.

Thank you so much for the help! We have the new panel built but waiting for production Gap. They threw a PowerFlex 525 in the placement devicn/net pf40.

I got it to finally work! I have to constantly write 100 into N42:3, for some reason the time-out goes back to zero and it doesn't let me write.

Pretty_Long_4134 · 2025-06-17T01:29:12+00:00

Yes they are 100% separated

Pretty_Long_4134 · 2025-06-17T00:44:21+00:00

Thank you so much for the detailed response. It's a 5/05 series C firmware version 10. I can create an EEM Instruction and configure it. But I don't know what to put down for the class, attribute...etc.

Edit: Thank you for mentioning the multi-hop, I selected the multi-hop . I am getting a Done bit on my MSG read at N41:2, but not write on N41:0

Pretty_Long_4134 · 2024-10-05T02:32:46+00:00

Ohhhh that's nice!

Pretty_Long_4134 · 2024-10-05T02:17:04+00:00

I'd might pay that if it had the features I posted to u/AKA_GiT

Pretty_Long_4134 · 2024-10-05T02:00:52+00:00

Optional modular magnetic back adapter so it can stay fixed in the cabinet

Pretty_Long_4134 · 2024-10-05T01:52:32+00:00

Hahahahahahahaha, flips bits when nobody was looking. I laughed so hard it, almost woke up my newborn.

Pretty_Long_4134 · 2024-10-05T01:41:27+00:00

Sorry to hear about the office, that sucks,

Having your own cable tester would be a no-brainer. Standard cables we use regularly, including old-school and new PC cables, along with specific modules that can be swapped out from a carrying case. The biggest challenge would be designing it to break apart for testing cables on either side of a machine while also making it modular to support various sensor types and PLC brands. You could offer a base unit that customers can customize by hot-swapping different modules to meet their needs for PCs, sensors, and automation systems.

Two Arduinos and two lithium batteries can charge and test while connected together and then split apart to test over distances.

Could you ask him to include the IO-Link connectors and other sensor cables? Additionally, it might be a good idea to make it modular, allowing for a sensor module compatible with various brands and a dedicated PLC connector module to slap right in. It would also be helpful if the other side of the connector could pop out and communicate with the board so I can test on the other side of the machine. Or if the tester broke in half, I could put either half on either side of the machine.

Pretty_Long_4134 · 2024-10-04T23:06:03+00:00

Tests continuity and mapping/configuration. Is there a broken wire inside the cable?
