Modicon Modbus RTU Communication

Dear Javed88,

Did you resolve your problem? I met a same problem with modbus between Minilec Annunciator and RTU 560 of ABB. I tested the minilec with some softwares ModScan32, Modbus poll,... and this modbus function is always ok but with RTU 560 the Slave did not respond

Hi,

Could you please tell if this problem is resolved or not?. I am also facing the same issue. I am getting data from Minilec Annunciator panel In Modscan. But If I connect to my PLC then there is no communication
