*1 There may be restrictions in the device types and addresses that can be used for PLCs
not manufactured by OMRON. Refer to the connection diagrams for details.
*2 It is not possible to specify all PLC models that can be used. Test operation using the
actual PLC.
Connection Diagrams
The connection diagrams between PLCs and NV-series PTs are based on the NV3W with
24-VDC input power. The connector on other NV-series PTs must be changed as
described below for other models of NV-series PTs.
NV3W with 5-VDC Input Power
Pin 3 changes from FG to NC. Do not connect anything to pin 3.
When connecting the PT to a non-OMRON PLC, use an external 5-VDC power supply.
You must use an OMRON CS/CJ-series or CP-series PLC and an XW2Z-200T-4 Connect-
ing Cable to connect the internal PLC power to the PT. Operation may not be correct if any
other PLCs or cables are used.
NV4W/NV3Q (RS-232C Models)
Pin 6 changes from NC to RS and pin 7 changes from NC to CS. (These pins are not actu-
ally used.)
●
: Direct connection is possible to the CPU Unit of the PLC.
❍
: A Communications Unit or a cable to convert signals is required
to connect to these PLCs.
Blank: Not appraised.
