Notes:
1. When you do not use the MODBUS blocks in your program, then EXM CPU shall work as slave, in this case,
you can use the SCADA or touch screen to communicate with EXM via the LAN port. However, if MODBUS
BLOCKS had been used in your program, moreover, the communication type (comm Type) is Ethernet, then
EXM can not work as slave through Ethernet port
2. In your program, if the Modbus read/write blocks would be used, then you can use the EXM as the master
CPU to communicate with the slave ( i.e. x-Messenger or the devices from other supplier which supports the
standard MODBUS TCP communication protocol.) in Modbus network
