Explanation of parameters

Diagnostics: No supply voltage L+

Enabling of the diagnostics for no or insufficient supply voltage L+.

Diagnostics: Short-circuit to ground

Enabling of the diagnostics if a short-circuit of the actuator supply to ground occurs.

Diagnostics: Short-circuit to L+

Enabling of the diagnostics if a short-circuit of the actuator supply to L+ occurs.

Diagnostics: Wire break

Enabling of the diagnostics if the line to the actuator is broken.

Channel activated

Determines whether a channel is activated or deactivated.

Reaction to CPU STOP

Determines the behavior of the module in the event of a CPU STOP.

Potential group

A potential group consists of a group of directly adjacent I/O modules within an ET 200SP

station, which are supplied via a common supply voltage.

A potential group begins with a light-colored BaseUnit through which the required voltage is

supplied for all modules of the potential group. The light-colored BaseUnit interrupts the

three self-assembling voltage buses P1, P2 and AUX to the left neighbor.

All additional I/O modules of this potential group are plugged into dark-colored BaseUnits.

You take the potential of the self-assembling voltage buses P1, P2 and AUX from the left

neighbor.

A potential group ends with the dark-colored BaseUnit, which follows a light-colored

BaseUnit or server module in the station configuration.
