To operate an Inline station you must provide the supply voltage for the bus coupler, the
logic of the terminals, and the sensors and actuators.
Connect the power supplies using unshielded cables as described in "Connecting
unshielded cables" on page 10-1.
When using Inline Block IO modules, the supply voltage for the module and the sensors and
actuators must be provided. Depending on the module, connection can be via Inline
connector or COMBICON connector.
The power supplies are connected using unshielded cables. For connection via Inline
connector, see "Connecting unshielded cables" on page 10-1.
10.2.1
Bus coupler supply
Power terminal supply
Depending on the type of power terminal, the following supply voltages can be supplied or
provided:
–

For the connector pin assignment of the supply voltage connections, please refer to the
terminal-specific data sheets for bus couplers, power terminals, and segment terminals.
For the connector pin assignments for connecting supply voltages, please refer to the
relevant module-specific data sheet.
For detailed information, please refer to the documentation for your bus coupler.
