750-882 Media Redundancy ETHERNET Controller
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.

*) 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.
The specialty modules represent 1x8 bytes input data and seize 1 Instance in
Class (0x67).

750-637
The above Incremental Encoder Interface Module has a total of 6 bytes of user
data in both the Input and Output Process Image (4 bytes of encoder data and 2
bytes of control/status). The following table illustrates the Input and Output
Process Image, which have 4 words mapped into each image. Word alignment is
applied.
