244 • I/O Modules
Process Data Architecture for EtherNet/IP
The specialty modules represent 1x6 bytes input and output data and seize 1
Instance in Class (0x67) and 1 Instance in Class (0x68).
Data Exchange Module
750-654, (and the variation /000-001)
The Data Exchange modules have a total of 4 bytes of user data in both the
Input and Output Process Image. The following tables illustrate the Input and
Output Process Image, which has a total of 2 words mapped into each image.
Word alignment is applied.
The specialty modules represent 2x2 bytes input and output data and seize 2
Instances in Class (0x67) and 2 Instances in Class (0x68).
