IO Link/Remote I/O Instruction (SG2-20Vxxx model only)
The SG2-20Vxxx models include the capability to link additional SG2-20Vxx
units via the RS-485 connection te

minals. The baud rate and communication
format both can be set using the

menu selection
from the SG2 Client software. They also can be set through keypad like adjacent
picture. The two bits of keypad how to decide the communication format and
baud rate like describing below.

IO Link
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),
