DI DO port can support the NPN or PNP:

(1) Digital input circuit

①When the upper device is relay output

②When the upper device is open collector output

(2) Digital output circuit

①When the upper device is relay input

②When the upper device is optocoupler input

Note:The maximum current should not exceed 50mA

And for the Pulse input and direction input,VD2,VD2F,VD2L can support the PNP connect too.

PLC 24V--PLC OUTPUT COM
PLC Y0/Y1 --SERVO PULS/SIGN
PLC 0V--SERVO PL

For example VD2 wiring:

And for VD2F/VD2L:

14(SIGN+) - direction Y1
12(PULS+) - pulse output Y0
11(PL) - 0V
PLC com - 24V
and 24V and 0V need in the same power
