WARNING : Always be careful when mapping directly to Output variables. While
it may be desirable to do so in certain applications, be advised that if you do, you
will be giving direct control of mapped outputs to any remote device that
communicates over your Modbus interface. It is generally more advisable to map
to a Memory variable, so that your PointeControl program can check incoming
commands and verify they should be executed.
8.2.3 Enabling the Modbus driver
To enable the Modbus driver on the Pointe Controller unit:
1. Launch the PointeControl Framework and open your project.
2. From the Project menu, choose Configure Modbus Mapping. The
Modbus Driver Configuration window will appear.
3. To enable Modbus communication via Ethernet, click the Ethernet TCP
checkbox. No additional configuration is needed.
