750-631, /000-001 Incremental Encoder Interface - WAGO -I/O-SYSTEM 750 User's Installation And Configuration

The module is seen like an analog input with 2 x 16 Bit input data, i.e. with a
total of 4 bytes user data. With word-alignment 2 words are used in the input
area of the local process image.

3.1.4.3.5 750-631, /000-001 Incremental Encoder Interface

This process data architecture holds true for the Incremental Encoder Interface
modules 750-631 and 750–631/000-001.
Item-No.:
750-631
750-631/000-001
The bus module 750-631 and 750-631/000-001 002 appears with 6 bytes of
input and 6 bytes of output data and occupying 4 words each with word-align-
ment.
Address
Offset
In the low byte, the control/status byte is on offset 0.
The data word D0/D1 contains the counter word (read/set), whereas the data
word D3/D4 contains the latch word (read).
