750-638
The 750-638 counter module has a total of 6 bytes of user data in both the
Input and Output Process Image (4 bytes of counter data and 2 bytes of
control/status). The two counter values are supplied as 16 bits. Each counter
has its own control/status byte. The following tables illustrate the Input and
Output Process Image, which has 4 words mapped into each image. Word
alignment is applied.

Pulse width Modules:
750-511, /000-002
The above 750-511 Pulse Width modules have a total of 8 bytes of user data in
both the Input and Output Process Image (4 bytes of channel data and 2 bytes
of control/status). The two channel values are supplied as 16 bits. Each
channel has its own control/status byte. The following table illustrates the
