1) Can also be used as a serial data port, e.g. to connect a terminal; but this hampers troubleshooting with the

debugger

2) Ethernet TCP/IP available as a configured system: PCD1.M130F655 / PCD1.M135F655. If installed later, the cover

must be replaced (item-no. 4 104 7409 0)

3) We recommend ordering the PCD2.D16x terminal kit mounted on the controller. If installed later, the cover must be

replaced (item-no. 4 104 7338 0)
