Hello, i have a process statition that colects data thorugh modbus tcp protocol, I have a problem, on some occations when the server reboots, the data collecting services do not work, and the system does not give me any error messages, just no data. I have checked the connection settings and everithing is ok, but the problem persists until another restart of the server. Any help please. My systems is running proview 4.7

Hi Canelon,

It could be the Halt CycleSup under the PlcThread object that is activated. You can see on the DelayCount and DelayTime if it is activated. It will set the IOReadWrite flag in the IOHandler object to 0 and stop the I/O. If this is the problem, increase the MaxDelay time.

If there is an init problem with the modbus this should be written in the log file.
