BE encoder and BA encoder simulation
To be able to simulate or evaluate encoders on binary interfaces, you must
place one of the terminal modules XI6, RI6 or IO6 in operation.
To evaluate single-ended incremental or pulse/directional signals, use binary
inputs BE3, BE4 and BE5. If you would like to simulate them, use outputs BA1
and BA2.
Hall encoders are connected to binary inputs BE1, BE2 and BE3.

Calculation example
– limit frequency
...
for encoder with 2,048 pulses per revolution:
3,000 revolutions per minute (equivalent to 50 revolutions per
second) * 2,048 pulses per revolution
= 102,400 pulses per second
= 102.4 kHz
