Connect the NET cable-1 to the RIO1 connector (R6) on the front of the control unit
(R6x2CPU) in 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.
The unit could malfunction because of noise if the shield cable is not used.
