Hi phumaj,
Thanks for your prompt response and for pointing me toward the communication tracing feature.
After enabling “Communication tracing” under the “Line parameters” tab, I reviewed the corresponding .log
files in the Trace directory. The logs indicate that the communication line is active, and the station is responding without errors. However, the tag values in the IDE remain static, even though manual checks confirm that the values are updating correctly.
I’m utilizing the Modbus TCP protocol for communication. The line status is True
, and the station statuses are as follows: STON
is True
, STCOMERR
is False
, and STHARDERR
is False
.
I also attempted to monitor the tag values using the Cnf tool, as you suggested, and observed that the values are updating correctly there. This leads me to believe that the issue might be specific to the IDE’s display or refresh mechanism.
Could there be a setting within the IDE that controls the real-time display of tag values? Alternatively, is there a known issue with the IDE’s tag monitoring feature when using Modbus TCP? Any insights or suggestions you might have would be greatly appreciated.
Thank you for your assistance.
Best regards,
HJ Bishop
