Connect the NET cable-1 to the RIO connector on the back of the controller. Each unit is connected to from a
daisy chain.
Always install a terminator (R-TM) to the last unit.
Note) Use a shield cable for NET cable-1 as a measure against noise.
Always connect the shield to FG. Install the attached ferrite core in both ends.
The unit could malfunction because of noise if the shield cable is not used.
