3.3.2 Explanation of the parameters
Diagnostics: Missing load voltage 2L+
Enabling of the diagnostics for missing or insufficient load voltage 2L+.
Diagnostics: Short-circuit to ground
Enabling of the diagnostics, at short-circuit of an encoder supply or of an output to ground.
Freely assignable channel
With this parameter, you set whether the channel is to be operated as an input or output.
You can only set this parameter in the DIQ and DIQ with value status configuration modes.
Reaction to CPU/master STOP
With this parameter, you set the reaction of the channels configured as output of the digital
input/output module after a CPU/master STOP:
•
Deactivate: The digital output is de-energized.
• Keep last value: The last value of the digital output remains activated.
• Output substitute value: The module outputs a configured substitute value.
Substitute value channel
With this parameter, you set substitute values for the digital outputs.
Input delay
This parameter can be used to avoid signal faults. Changes to the signal are only detected if
they are present and stable for longer than the set input delay time.
You cannot set this parameter in DQ16 mode.
