Each channel has its own output filters. These output filters always work with maximum
resolution.
Output filters are also in effect when the module is to output substitute values, for example,
after CPU STOP or in case of a communication failure.
This means all transitions are still smooth and infrared sources for hot gluing spots do not fail
immediately, for example, but are shut down slowly to ensure that the surface of the gluing
spots does not tear due to sudden cooling.
If you do not want to use output filters, use the parameter setting "No filter".
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.
