Mohd abdulsattar Posts: 3 Rating: (0)	I have S7-400H sys, include CPU-412-3H and 3 CP443-1 modules in each rack. one cp to communicate with DCS works as server. one cp to communicate with 19 M300 power meter works as client One cp for opc server. I am using Modb4H, the communication betwwen first cp and DCS is working well. the problem statrted when I added another two connection between the seconed cp and 2 M300, I am recieving A083 code in the status word for Modb4H which I am using for the 2 M300 and the communication for dcs still working. however I alawys trigger the seconed task after ensuring that First task has finished through checking error/done bit. is there any one has idea about this problem, or anyone has agood way for triggering. please attach a sample for triggering. thanks in advance.

Tomcat Posts: 433 Rating: (48)	Hi, which version of ModbusRed do you use? A083 means, that you started a new request with ENQ_ENR = TRUE before the previous order was finished. You have to wait until DONE_NDR or ERROR is TRUE. After this you can start a new request. Tomcat
