5.4 Controller & IO Module
The 2-head cable is necessary to connect the controller（via RIO port） and the IO module for 22/220 series
controller.
The part NO. of the cable isW01-RIO-EX and shown as below.
The extension cable for RIO is usually needed.
The 1-head side of the cable is used to connect to the RIO port of the controller.
For the 2-head side of the cable, there are marks of P1 & P2, P1 is connecting to the operation panel and P2 is
for IO module, like RIO module or iTB terminal board.
There are two types of iTB terminal board, iTB-3232 & iTB-1616, the number means 32 inputs/ 32
outputs and 16 inputs / 16 outputs.
If iTB-3232 is used, you can get 16 more inputs by connecting to additional TB-16IN terminal board.
When you set Pr5 of the controller as 7, the panel and IO module could be activated via RIO port of the
controller. Notice that the 2-head cable should be connected correctly.
5.5 Controller & SRI Device（Optional）
The option I/O port on the controller can connect 1 SRI device like FC module and 1 RS485 interface at the
same time.
Syntec standard cable for option I/O only support FC module because only pin 1 & pin 2 of the cable are
functional.
If you want to connect to RS485 interface, you need to customize the cable to make pin 6 & pin 7 functional.
