Digital part - Counter - Functions
The combination module has 3 parameterizable integrated counter that are
controlled via the input channels. During the counter process, the counter
signal is registered and evaluated. Operating mode and additional functions
are set via the parameterization.
For the counter, the following operating modes are available:
• Count endless – Distance measuring with incremental encoder
• Count once – Count to a maximum limit
• Count periodic– Count with repeated counter process
The operating modes "Count once" and "Count periodic“ allow you to
transfer the counter area as start res. end value via the parameterization.
Each counter is parameterizable with additional functions like gate function,
latch function, comparison, hysteresis a process alarm.
For every counter, the following inputs are available:
Pulse/A (A
x
)
Pulse input for counter signal res. line A of an encoder. Here you may
connect encoders with 1-, 2- or 4-thread evaluation.
Direction/B (B
x
)
Here you connect the direction signal res. line B of the encoder.
You may invert the direction signal by parameterization.
Latch (L
x
)
A positive edge at the digital input „Latch“ stores the recent internal counter
value.
HW Gate (G
x
)
You start the counter via the digital input „Hardware gate“.
Every counter has an assigned output channel. You may set the following
behavior for the according output channel via the parameterization:
• No comparison: Output is not called
• Counter value ≥ comparison value: Output is set
• Counter value ≤ comparison value: Output is set
• Pulse at comparison value: Set output for a configurable pulse duration
