How do I find the y0c?

Meaning need to do some program to on it? But the modbus is at rio rack? Any ways to save the ram? 

meaning y0 i need to enable so that everytime power cycle the module will auto start?

I have this module that is currently polling some modbus adddress. Problem i am facing is everytime this module is power cycle, i have to manually on back the communication via the function utiliy. how do i auto start this communication? 

Any idea where to check the message? 

I had modscan the holding register exist. So far now I only enable 1 node address yet return error 7360  'Exception message reception'.  . 

Guys, any valuable advise for me on the qj71mb91 module? The issue is that I keep getting the error code 7360 'Exception message reception'. I had tested the loop cable is working via modscan and the rio is able to pool data via modsim to prove my configuration works but the moment I connected the vsd loop, no data get and the error code keep coming? I am using iec development software.
