12.2 Connecting the power supplies

Inline 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 Section “Connecting

unshielded cables” on page 128.

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.

Inline Block IO 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 Section “Connecting unshielded cables” on page 128.

For the connector pin assignments for connecting supply voltages, please refer to

the relevant module-specific data sheet.

12.2.1 Inline: Supply options

Bus coupler supply

For detailed information, please refer to the documentation for your bus coupler.

Power terminal supply

Depending on the type of power terminal, the following supply voltages can be supplied

or provided:

– U

M

and U

S

(I/O supply voltage)

– U

24V

(generation of U

L

and U

ANA

), U

M

, and U

S

(communications power and I/O supply

voltage)

Please also refer to the information provided in Section “Power, segment, and ac-

cessory terminals” on page 30.

Providing the segment voltage at segment terminals

At segment terminals, the segment voltage U

S

is provided from the main circuit U

M

.

Please also refer to the information provided in Section “Power, segment, and ac-

cessory terminals” on page 30.

Notes on supply voltages

The bus coupler supplies the module electronics of the connected terminals with com-

munications power (U

L

), which is generated, for example, from the bus coupler supply

voltage (U

BK

). If the supply voltage U

BK

is disconnected, the bus stops.

The supply voltage to the sensors and actuators (U

M

/U

S

) should be installed and

protected independently of the bus coupler supply (U

BK

). In this way the bus continues

to run even if some I/O devices are switched off.
