  If control is performed with a central device (such as central controller), a 

group number needs to be set with the remote controller. 

  See the manual of each central device for details. 

y

  Even when the central device is used for controls, you still use the remote 

controller to change field settings. Install the remote controller in an 
operable location. 

For remote operations

y

  Remote operation can be performed by connecting the external input 

(Input A) to terminals J1, J2, and JC of the terminal block (X2M).
