Specialty Modules
750-635, 753-635
The above Digital Pulse Interface module has a total of 4 bytes of user data in
both the Input and Output Process Image (3 bytes of module data and 1 byte of
control/status). The following table illustrates the Input and Output Process
Image, which have 2 words mapped into each image. Word alignment is
applied.
RTC Module
750-640
The RTC Module module has a total of 6 bytes of user data in both the Input
and Output Process Image (4 bytes of module data and 1 byte of control/status
and 1 byte ID for command). The following table illustrates the Input and
Output Process Image, which have 3 words mapped into each image. Word
alignment is applied.
DALI/DSI Master Module
750-641
The DALI/DSI Master module has a total of 6 bytes of user data in both the
Input and Output Process Image (5 bytes of module data and 1 byte of
control/status). The following tables illustrate the Input and Output Process
Image, which have 3 words mapped into each image. Word alignment is
applied.
