Note 1: When connecting an NSJ Controller to a computer or PLC, always use the serial port or
Ethernet port on the Display Section. The above connection method is not possible if the NSJ
Controller is connected to an Expansion Unit or serial port on the Controller Section.
Note 2: If you connect the PT to PLC 1 using a serial connection, you will not be able to connect online
to PLC 2 or PLC 3 across the network layers.
The CX-Integrator cannot be used if the computer is connected to the PLC through a PT.
Screen display refresh speed and touch panel response may be slower when the CX-
Programmer is connected through a PT.
