You're talking about GuardLogix and Safety Modules but also about Machine Redundancy. IIRC, Guardlogix Safety was not actually compatible with the Enhanced Redundancy Modules (1756 -RM2). Before the 5580 series, you needed the 1756-LSP module to do functional Safety, but it was a Safety Co-processor ...

For Safety Consumed Tags, there is a parameter called Max Network Delay. I think I've also seen it written as "Maximum Observed Network Delay". How do I access this value from within the PLC programming? Can I reset the Max from in the PLC program? or is there just an "Observed Network Delay" value ...

Yes, that is correct. We're doing both standard and safety tags, currently have 3 Produced/Consumed tag pairs on each PLC (So each PLC (L82ES connected through onboard ethernet) is both producing for the other and consuming from the other PLC) The tags are 1x standard tag with just a DINT and 2x Safety ...

Can someone point me towards documentation that details the criteria the processor uses to determine whether its ethernet connection with another processor is good or faulted? I'm looking for something that goes down to the details of ethernet packet loss/out of sequence, data mismatch, etc. Our network ...

Have you tried the pycomm libraryfor Python? Not sure if you'll be able to get the resolution you'd get with a direct packet capture, but it relies on CIP messaging and data types, so it may be easier to query specific tags at a regular interval instead of trying to capture and decode transmitted ...

I figured it out. Our DSL Modem is addressed 192.168.0.10 even though we are individually given a 10.0.X.X address. Whenever I thought I was pinging PLC A, I was actually pinging our DSL Model through the wireless. (I'm not sure why I could connect PLC A when I was connected directly to it...) I changed ...

Oops, sorry. It is the EN2TR with the 2 ethernet ports. We've used them before in a daisy-chained configuration so I assumed it just acted like an internal 3-port switch. I'm connecting them to each other with an ethernet cable and plugging my PC into the remaining port on the card.

Probably simple problem, but I've been messing with it for a few days now. We have a test-stand of 2x ControlLogix 4-slot racks. L83 Proc in Slot 0, EN2T EN2TR in Slot 3. LAN A on Rack A is directly connected to LAN A on the Rack B. PC is connected to LAN B of either Rack's EN2T EN2TR . (The program ...
