Wiring Connection Block M12, 7/8 - Siemens ASM 456 Operating Instructions Manual

4.3

Wiring connection block M12, 7/8"

Properties
● Connect the supply voltages and PROFIBUS DP to connection block M12, 7/8".
– M12 connection: PROFIBUS DP
– 7/8" connection: Supply voltages
● You can loop the supply voltages and PROFIBUS DP through via M12 and/or 7/8" round
sockets.
● On nodes (ASM 456) at the beginning or end of a PROFIBUS DP chain, a terminating
resistor must be turned on.
Requirements
● Wire connection block M12, 7/8" when the supply voltage is switched off.
● The PROFIBUS address is set according to your configuration, and the terminating
resistor is switched on if required.
Tools required
Stripping tool, screwdriver for wiring the M12 or 7/8" connector if you are not using a pre-
assembled connector.
Required accessories
● Preassembled cables with connectors
● If you do not use preassembled connectors:
– M12: 2-core cable, shielded (bus cable) and M12 connector (see "Connection
– 7/8": 5-core cable and 7/8" connector (see "Connection assignment for 7/8" connector
● M12 terminating resistor for PROFIBUS DP
● For order numbers, refer to the section "Ordering data".
