Answer question
Modbus RTU communication Error
Hi,
I tried to communicate 6 ABB vfd drive (ACS560) to PM554-TP-ETH via modbus RTU. When all the drives are in idle condition the communication is good . for the application to read 3 values from each drives. when any one of vfd is in running condition i got error in each 6 block (ACS_COM_MOD_RTU) .
then i tried to communicated each drives individually the same issues exists.
Error Numbers are :
1. 8216 (check sum error).
2.28685(Function Block Read_Parameters has been executed with error).
I don't why those error come only in running condition not in idle condition.
kindly guide me to solve this issue.
