Hi All, I have programmed some MSG instruction in SLC5/05 64k CPU series D FW 13 brand new cpu.
2 of the MSG instructions are direct IP to other 5/05s and 2 are MultiHop to 5/04s via a Control logix DH+/ RIO bridge. The Message instructions all are triggered by 10 second self resetting timers.
All the message instruction work fine, the problem is when I unplug the remote CPU's to test the Error messages.
First I removed the target 5/04 and the MSG timed out with no replay and i get the MSG Error bit on. Which is what I expected. ( everytime the MSG ins is enabled vai the free running timer the Enable bit blips on then straight back to error.) So no issues with this - normal behaviour.
When I remove the target 5/05 I get the error bit on for 3 seconds and the Enable bit on for 15 seconds. Even though it's a 10 second trigger timer. Which I know is the default timeouts for Channel 1 ethernet port. But my question is why the different behaviours for the MSGs. ? is it to do with one being MultiHop and the other direct IP. But if so why.
Any help greatly appreciated.
