I am writing a MODBUS RTU slave application. I need to use exception code "05 - Acknowledge", because I have long lasting processes in the application.
The ModBus Protocol Ref. Guide defines exception code 5, which seems to fulfill my needs by stating "...The master can next issue a Poll Program Complete message....". But I have not anywhere found a description of such a message.
Does anybody know where and how this messagetype is defined?
