MODBUS communication status code: -7006
slave is GE MARK system and master is ABB CI867 module. Whenever I disconnect cable and reconnect, DCS can't find slave( no response from slave : status code: -7006)
if any of you have some experiences can you help me?
I was also experiened similar kind of problem in one of my previous pojects, When you disconnect the cable it takes almost 10 mins to reconnect ,if you reset the power it comes quickly.
I feel there is no solution i found, even i checked it with wireshark the response is same.
instead of disconnect the cable you may need to restart the module.
Please ensure the the following:
1.Cable is not connected to CH2(10MBps half duplex) since it doesn't support cable break detection feature.
2.don't use hub/repeater between two since it increases the failover time.
Please explain in breif, are you using direct connection between the two system or you have introduced multiple switches between these
Am able to find one product bulletin please follow the procedure to fix the same.
Can you share the control log files.?
