I am using Jamod for Modbus communication with Allen Bradley ML1400B. All goes well for writing a single register, and the data gets reflected immediately.
However, if I read the registers back, I get old values. Then if I start Modbus Poll to connect to the PLC, the Jamod starts giving correct values. I don't see any apparent reason for this anomaly, and request the experts to help me!
Thanks,
