5.2.4 Assignment of EC Connection Unit
The assignment of the EC connection unit should be as shown below.
The EC connection unit occupies domains for four axes (one word) even though not all of four
axes are connected.
PLC output = Axis control signal
Address
*
PLC input = Axis status signal
Address
*
* m is the head register address of each unit. n is the head relative address of each unit.
p is the head module address of each unit.
CC-Link, CC-Link IE Field, and DeviceNet have word addresses, PROFIBUS-DP, EtherNet/IP, and
EtherCAT use byte addresses, and PROFINET IO uses 4-word module addresses.
