Hardware inputs/outputs
Clock generator input (A) / Pulse input (A) / Clock generator forward (A)
This parameter specifies which input is used for the encoder signal A for the respective
counter. The value cannot be changed.
Clock generator input (B) / Pulse input (B) / Clock generator forward (B)
If you use an encoder with multiple signals for the respective counter, this parameter
specifies which input is used for the encoder signal B. The value cannot be changed.
Reset input (N)
If you use an incremental encoder for the respective counter, this parameter specifies which
input is used for the reset input (encoder signal N). The value cannot be changed.
HSC DI0 / HSC DI1
This parameter determines which digital input of the Compact CPU is to be used as the DIm
of the counter.
Note
You can configure the input delay for a digital input in the Inspector window of the device
configuration under "Properties > DI 16/DQ 16 > Inputs > Channel n".
HSC DQ0
You can read the status of the DQ0 via the feedback interface. You cannot assign DQ0 to a
physical digital output of the Compact CPU.
HSC DQ1
This parameter determines which digital output of the Compact CPU is to be used as DQ1.
You can select an output with an output delay of 5 µs or 500 µs.
You can find an overview of the output delay for all digital outputs in the device manual of the
Compact CPU.
