Notes:
1. When you do not use the MODBUS blocks in your program, then ELC-22DC-DA-R-N CPU shall work as
slave, in this case, you can use the SCADA or touch screen to communicate with ELC-22DC-DA-R-N via
the LAN port. However, if MODBUS BLOCKS had been used in your program, moreover, the
communication type (comm Type) is Ethernet, then ELC-22DC-DA-R-N 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
ELC-22DC-DA-R-N as the master CPU to communicate with the slave ( i.e. xlogic or the devices from
other supplier which supports the standard MODBUS TCP communication protocol.) in Modbus network
