Status bit to catch an ethernet communication fault

1 post in this topic

Hi all, (about 1769-L30ER CompactLogix 5370 Controller + Generic Ethernet Module) I have a quick question on how to trap a signal in RSLogix 5000. I have an ABB Pluto Safety PLC (Pluto 0 = B46, Pluto 1 = B20) in my System and communicate with them via an ethernet gateway (also from ABB). My suspicion is, that the Ethernet Gateway drops communication sometimes and I miss Signals, which causes my machine to stop. It is a generic Ethernet-Module 1.1) See screenshots attached. I'm wondering if there is a status bit available that I could use to latch in an internal bool flag/marker if I loose communication with that ethernet module. I noticed that sometimes the I/O status led on my 1769-L30ER CompactLogix 5370 Controller starts flashing. If someone can please let me know in which direction I need to look here, to find a status bit in my PLC to set-up a trap. Thanks guys! Studiologe
