Dear Pegaia Sir,

I am Communicating 4 Nos G120 Drives With 1214C CPU , Read/ Write is OK .

But

when any of the Drive Communication is disconnected then the next all drives show communication Error & stop communicating  & the drive with Preceding address remain communicating.

I have taken the error bit individually of the all 4 Drives MB_MASTER Block & set a bit  in series with EN input of that Particular Drive MB_MASTER Block but that does not help , all other next addressed drives still does not communicate.

Pl advice
