IO Link Function
Function Description:
Up to 8 SG2 units can be linked together as the IO Link Network. Each unit runs their own logic program; the
ON/OFF state of input, output points, and Auxiliary Coils in each one can be assigned to “W Table”, see the next
page for more information. There must be one master (ID=00) and several slavers with the continuous ID number
starting from 01 in the network. The master one does not perform the IO Link function to the units with the ID
behind the first broken number once the ID numbers are not continuous. For example, the slavers’ ID are 01, 02, 04
and 05, the master just can recognize only two Slaver, ID 01 and 02, the ID 04 and 05 will be skipped.
One controller can use 8 IO Link (L01~L08). Only one IO Link instruction can work at Mode 1(Write
mode), and the other IO Link instructions must be Mode 2 (Grab mode).
The Mode 1: Write the ON/OFF states of the selected coils into the chosen W elements. The available W
elements in the mode 1 depend on the ID setting of that unit, refer to the table in the previous page for more
information.
The Mode 2: Grab the states of the selected W elements, and substituting the state of the selected coil. If the
select coil type is input coil I or X, coil status can’t be changed by the state of W elements.
Hardware Configuration:
1. Link not more 8 RS485 type SG2 as show below.
2. Set all the SG2 in SET menu to No Remote IO.
3. Set those SG2’s ID continuously 00, 01, 02… The max number of the ID is 07.
