The above Counter Modules have a total of 6 bytes of user data in both the In-
put and Output Process Image (4 bytes of counter data and 2 bytes of con-
trol/status). The two counter values are supplied as 16 bits. The following ta-
bles illustrate the Input and Output Process Image, which has a total of 6 bytes
mapped into each image.

Pulse Width Modules
750-511, (and all variations)
The above Pulse Width modules have a total of 6 bytes of user data in both the
Input and Output Process Image (4 bytes of channel data and 2 bytes of con-
trol/status). The two channel values are supplied as 16 bits. Each channel has
its own control/status byte. The following table illustrates the Input and Output
Process Image, which has a total of 6 bytes mapped into each image.
