time, status event and write data exchanges with the same exchange
number are internally linked in the ETC II to the same device address.
2.
Specify the start register address of the area in the device Modbus map
you wish to be written via the exchange.
3.
Type the number of contiguous registers in the exchange.
4.
Check the “Write Enabled” box to activate the exchange.
