See Technical specifications of the interfaces (Page 359).
ASM cable
The connectors are already fitted to the ASM cable.
● Using the ASM cable, you connect the communication modules, for example RF180C
and ASM456.
For SIMATIC MV420, a special ASM cable with M16 socket is available. Refer to the
chapter "Cables" (Page 370).
