750-637
The above Incremental Encoder Interface Module has a total of 6 bytes of user
data in both the Input and Output Process Image (4 bytes of encoder data and
2 bytes of control/status). The following table illustrates the Input and Output
Process Image, which have 6 bytes mapped into each image.
The specialty modules represent 2x3 bytes input and output data and seize 2
Instances in Class (0x67) and 2 Instances in Class (0x68).
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 4 bytes mapped into each image.
The specialty modules represent 1x4 bytes input and output data and seize 1
Instance in Class (0x67) and 1 Instance in Class (0x68).
RTC Module
