Usage as X4 Counting DeviceΒΆ

The function module DC541-CM supports an encoder counting mode with channels A/B. This counting mode usually just supports to count 1 edge out of possible 4 edges from the 2 encoder lines. These are connected to C0 and C1 on DC541-CM.

Counting in X4-mode

For increasing the accuracy, it is possible to use a special mode with counting all 4 edges. This mode just supports a frequency up to 4 kHz. Despite of counting 4 edges on a lower frequency, the functionality is the same as 32 bit encoder on channel 0 and 1 and also the same Function Block DC541_32BIT_CNT: DC541_32BIT_CNT
