Configuration
The module has the following configuration options:
Outputs
} Deactivate fast shutdown for individual outputs
Default value:
The fast shutdown is activated for all outputs
} Output test for single-pole outputs
Default value:
The output test is activated for all single-pole outputs
Inputs:
} Test pulses
Default value:
The test pulses are activated for all inputs
} Edge used to trigger the fast shutdown
Default values:
Inputs for fast shutdown:
– I00 ... I07: Fast shutdown with falling edge
} Filter times (default: 300 µs)
The input filter time can be configured separately for inputs with and without fast shutdown.
The input filter time can be configured in increments of 100 µs. The input filter time depends
on the edge configured for fast shutdown. For each input filter time that is configured, there
are two values each for the rising and the falling edge:
