Incremental Encoder Interface Modules
750-631
The above Incremental Encoder Interface modules have 5 bytes of input data
and 3 bytes of output data. The following tables illustrate the Input and Output
Process Image, which have 4 words into each image. Word alignment is
applied.
The specialty modules represent 1x6 bytes input data and seize 1 Instance in
Class (0x67).
And the specialty modules represent 1x6 bytes output data and seize 1
Instance in Class (0x68).
750-634
The above Incremental Encoder Interface module has 5 bytes of input data (6
bytes in cycle duration measurement mode) and 3 bytes of output data. The
following tables illustrate the Input and Output Process Image, which has 4
words mapped into each image. Word alignment is applied.
The specialty modules represent 1x6 bytes input data and seize 1 Instance in
Class (0x67).

If cycle duration measurement mode is enabled in the control byte, the cycle
duration is given as a 24-bit value that is stored in D2 together with D3/D4.
