Using DeviceNet Explicit Messaging
Writing to Register Objects
Within the Enhanced DeviceNet adapter, various register objects
buffer I/O in the following fashion (RO=Read Only,
R/PW=Read/Write Protected):
Refer to the “Class Code 0x07 — Register Object” section in
Appendix C, DeviceNet Objects for more information on the Register
Object.

Logic Command (Last Logic Command is ANDed with the first word in this
command and ORed with the second word in the command. The reference is not
modified. This command allows bit changes to the logic command without
affecting the speed reference or other control bits.)
