The goal of this function is to connect an encoder to acquire a position.
This function can be installed on the embedded Expert I/O module (DM72F0 and DM72F1) and the Encoder interface (Sub-D).
When implemented on an Expert I/O interface, the encoder only supports the Incremental mode.
When implemented on the Encoder interface, the encoder has 2 possible modes:
On the Encoder interface, the power supply is monitored. A power supply error detected is cleared automatically when the power supply recovers.
Optional features can be configured depending on the selected mode:
ohardware inputs to operate the counter (enable, preset) or capture the current counting value
oup to 4 thresholds
oup to 4 events (1 by threshold) can be associated with external tasks
oup to 2 reflex outputs
Maximum admissible frequency:
oExpert I/O module: 100 kHz.
oEncoder interface: 200 kHz.
