Class Name = Module
Instance Name is the device....just drag your device name from the I/O tree
Attribute Name = EntryStatus
Dest = a DINT tag that you declare
Once you program this instruction, DIV EntryStatus by 4096 into another DINT tag that you declare, and compare this second DINT tag to a value of 4. If it's equal to 4, then your comms are OK. Anything else, your comms are not ok.
The only other suggestion is you might want to condition your GSV call on some interval, such as every second or every few seconds...whatever you can live with for detecting a fault. Because each GSV call takes some system overhead to accomplish, so if you're calling it every scan when you don't need to, its not efficient to do so. Probably won't matter if that's your only GSV and only ethernet device. But if you're polling 100 devices, then it adds up.
