  1. Open Workstation and navigate to [AS/ES name]/System/Modules/Trace/Loggers/nsp/nsp.pin.
  2. Right-click "nsp.pin.modbus" and choose properties.
  3. Under Level, change from "Information" to "Trace", then click ok.
  4. Let it run a few minutes. If there are some user input needed to recreate the modbus issue, do it.
  5. Retrieve the log by right-clicking [AS/ES name]/System/Modules/Trace/TraceSettings and choose Trace settings->Get trace log. 
  6. Save the log file somewhere you'll find it later.
  7. Change log level back to "Information" (reverse step 3).
