I/O Modbus Slave

UDP Unicast Example

For an example of the I/O UDP unicast, see the sample program, ioudpbcast.c, found on your CD- ROM.

I/O Modbus Slave

If you have a Modbus serial or TCP application, it can access I/O connected to the IOLAN when the I/O Global Modbus Slave is enabled. You must supply a unique UID for the IOLAN, as it will act as a Modbus Slave.

There are three ways your Modbus Application can connect to the IOLAN to access I/O.

Modbus Serial Application Connected to the Serial Port

Your Modbus serial application can be connected right to the IOLAN serial port to access I/O.
