Interface Module Installation & Reference
The WriteDeviceNetBuffer function sends incorrect data to the PLC
1. Check the RS232 settings on the Interface Module (be sure to upload from the device) and in the
Serial Port settings in the In-Sight user interface.
2. Check that the packet size is set the same on both sides of the RS232 connection, and that it is
the same as the packet size sent from the Interface Module to the PLC.
