Processor from Upload is different than controller
pcmccartney1 replied to joesalmans's topic in Allen Bradley / Rockwell Automation
Change your processor in the program to series B? -
Bob, this is how I'm checking lead times, as well as talking to my distributor. An Update on Our Global Supply Chain Lead Times | Rockwell Automation

addressing inputs outputs
pcmccartney1 replied to mmd604's topic in Allen Bradley / Rockwell Automation
Adding to Bob description, aliasing of inputs and outputs helps latter when an input or output point fails on a module. You have a spare and can make one change to the alias and not affect any other logic. -
Compact Logix 5370 Output Flickering
pcmccartney1 replied to Nick_D's topic in Allen Bradley / Rockwell Automation
Cross reference the Local:3:O.Data.4 to determine if something else is writing to it. You are looking for destructive references. -
Rockwell commuincation systems
pcmccartney1 replied to ABlearner's topic in Allen Bradley / Rockwell Automation
Nope. Go get the docs and read. All are still active, used and supported. You would best be served by focusing on E/IP. The others are relics and fading quickly. -
Replacing A Micrologix 1400 with Compactlogix?
pcmccartney1 replied to asteroidehk's topic in Allen Bradley / Rockwell Automation
The 1769 series of processors require a power supply. Since you only have a processor and two IO modules, position the power supply anywhere. The power supply is not assigned a slot. I suggest you arrange PLC, Input, PS, Output, Right End Cap. Honestly, the L30 is way to much PLC for your process. Probably an L16 or L18 could work as well for less cost. -
Devicenet net fault
pcmccartney1 replied to Sd.Kfz.182's topic in Allen Bradley / Rockwell Automation
We've done messages to inhibit and un-ihibit the scanner. Done the same this to inhibit and un-inhibit individual nodes. The issue comes that the scanner card must be idle or not enabled for scan. Even through Networx, I think to modify a node requires the the PLC to be in Program Mode. In Logix, the faulting of the card can be setup to fault the entire controller, but I don't think that's what you are looking for either. Not seeing a way for you to accomplish your task. -
If concerned with maturity of Omron's IO Link devices, consider ifmEfector. Been using them for several years successfully. Not sure we've used them with Omron as yet. But we use them with E/IP for Rockwell and Profinet with Siemens. Omron talks E/IP, dependent upon processor, you might need to add a comms module. Additionally, we use SMC valve banks via EX260 (IO Link) as a slave to the IO Link Master.

Very Slow Getting Online to SLC 5/05 Over Ethernet
pcmccartney1 replied to queenslandpommie's topic in Allen Bradley / Rockwell Automation
Might I also add for SLC and MLX, you should always have at least one service interrupt (SVC). Usually, second to last rung. This always for outside devices to have a time slice to talk to the SLC for devices like the SCADA, other PLCs and your PC. My last rung was always an unlatch of the math overflow error. This gives you a chance of diagnosing the offending logic that's causing the processor to fault. -
Yes. And ridiculous lead times on standard items and only getting worse.

How can we Monitor Wonderware Historian inside CompactLogic PLC/FactoryTalk HMI
pcmccartney1 replied to noorloai's topic in Allen Bradley / Rockwell Automation
Can the PLC poll the Historian rather than the Historian pushing the heartbeat to the PLC? MSG instruction, fired periodically, to read the status of the Historian heartbeat? -
I think you should post this in the GE Forum. Steve Bailey is an expert. If he doesn't know the answer, I'm sure he knows someone that does. Personally, I've done it thru the serial port of a Rockwell MicroLogix. Add code to scan for characters in the buffer. Confirm correct length. Then move the data and store in another location for additional logic and eventual display on HMI.

Control Logix GSV request
pcmccartney1 replied to photovoltaic's topic in Allen Bradley / Rockwell Automation
Might I suggest you use a full string rather than 40. It's lost the 176 at beginning of controller part number. -
Possibly a company called Esitron in Germany?

Is it possible to import a .wld file from a VIPA PLC into Speed 7 studio?
pcmccartney1 replied to Zamora's topic in Other PLCs
VIPa and Speed 7 seem to be a German owed platform by Yaskawa. Suggest you contact their technical support to figure out next steps. -
Try posting them in the Allen-Bradley forum and someone will create a PDF for each ACD.

FactoryTalk Studio Crashing
pcmccartney1 replied to ElectronGuru's topic in Allen Bradley / Rockwell Automation
Should have been able to convert project to v12 and create the MER at v10 for the PV. -
PVP 6 firmware update
pcmccartney1 replied to cavedog's topic in Allen Bradley / Rockwell Automation
There is nothing preventing you from create the MER at v10 from your v12 project. -
Panelview Panel + 7 900W Unable to connect
pcmccartney1 replied to lqu@edgeautomation.ca's topic in Allen Bradley / Rockwell Automation
I think it's because the MER is on an external drive. Put the MER in the standard Runtime folder and try downloading again. -
Panelview Panel + 7 900W Unable to connect
pcmccartney1 replied to lqu@edgeautomation.ca's topic in Allen Bradley / Rockwell Automation
Need to apply the shortcut to the PLC three spots up from the currently selected and then copy to runtime. -
79 indicates a failure to transmit a message. Make sure that your scanner is connected to a valid network. Did you assign the correct node address to the ADN? All device net nodes are set to 63 from the factory and must be changed to match the scan list configuration. Any chance the replaced ADN is the last node on the network and therefore must have a terminating resistor? This would be true for a straight line configuration with te other terminating resistor at the terminal of the 1769-SDN. In a "T" configuration, a terminator would be installed at the end of each.

Ethernet/ip Driver stopped working after node was removed
pcmccartney1 replied to IanM8040's topic in Allen Bradley / Rockwell Automation
Not sure this helps. I use VMWare and I setup my NIC as the bridged connection and VMnet8 as a NAT for my wireless. I use the NIC (bridged) when local to the PLC. I use wireless (VMnet8 NAT) for remote access work. Another trick is sometimes I have to disable one or the other to get a connection. -
AB 753 Drive output signal failure
pcmccartney1 replied to dmorph's topic in Allen Bradley / Rockwell Automation
Any chance the IGBTs are blown? -
Help with Sockets AB
pcmccartney1 replied to asteroidehk's topic in Allen Bradley / Rockwell Automation
You shouldn't need a Tech Connect contract. You should be able to create a free account and access all the Tech Notes. -
Need help with s7-300 and omron NX102 communication
pcmccartney1 replied to enesu's topic in Siemens
Sounds like an opportunity for a Red Lion DSP.
