Hi Friends,
From the Protocol Specification i understood that, ACKNOWLEDGE(0x05) is sent by the Slave device to Master, when it takes more time to perform the requested operation.
In response, to that Master can next issue a Poll Program Complete message to determine if processing is completed.
What is mean by "Poll Program Complete message" as described in Modbus_Application_Protocol_V1_1b.pdf, Page No: 49.
Thanks,
