IO Link function block
Up to 8 additional SG2 units can be configured as independent Slave nodes, each running their own logic program and
their I/O linked to one Master smart relay. The Master smart relay’s ID must be 00, and Slave nodes’ ID should
start with 01 and be continuous. If nodes’ ID isn’t continuous, the Master won’t communication with those
nodes which are behind the first broken. For example, the nodes’ ID is 01, 02, 04 and 05. The Master thinks
there are only two Slave nodes whose ID is 01 and 02, and communication with them.
Each controller can use 8 IO Link (L01~L08). Only one IO Link instruction can work at Mode 1(send mode),
and the other IO Link instructions must be Mode 2 (receive mode).
The Mode 1:
Send
memory range is dete

mined by the Controller ID. The adjacent table show the memory range of
Wxx locations associated with each controller ID.
The Mode 2: read the selected Wxx status and write to the selected coil. If the select coil type is input coil I or X, coil
status can’t be changed by Wxx status.
