Manual
Version 2.0.0
In Class 0x4, Instance 0x7 of the assembly object, the analog and digital input
data occupy 6 or 12 bytes. The output data occupy 6 or 12 bytes in Class 0x4,
Instance ID 0x1.
Incremental encoder interface
750-634
The incremental encoder interface module occupies 5 bytes in the input process
image, or 6 bytes in cycle duration measurement operating mode, and 3 bytes in
the output process image. 6 bytes are occupied in the process image.
