Hi Guys
I have been experiencing a communication issue with PV1400 ( 2711-K14C1) Showing a error message "65 No PLC communication"
The system is as follows
PV1400 is communicating with 1747-ASB Through RIO , and RIO Communicating with 1747-SN installed in SLC 5/03 Chassis.
System was working. I have done a small modification on ladder (LAD 4 RUNG 102-118) .After one hour since i download the modified program , HMI Start showing " NO PLC Communication .
indication on the SN module is flashing green , and ASB module showing RUN and steady green
We have check the cable continuity and baud rate , those are correct
Can you please suggest solution ?
SN module installed on slot1 on main chassis and ASB on slot 0 on a remote chassis
please PLC and HMI programs find below
