6-12 Using DeviceNet Explicit Messages
Writing to Register Objects Within the DeviceNet adapter, various register objects buffer I/O in
the following fashion (RO=Read Only, R/PW=Read/Protected
Write):
Refer to the “Class Code 0x07 — Register Object” section in
Appendix C, DeviceNet Objects for more information on the Register
Object.
Instance Access Size Function
1 RO See M-S Output Poll Response I/O data to controller
2 R/PW See M-S Output Buffered Poll I/O data from controller
3 RO 32 bits Logic Status & Feedback
4 R/PW 32 bits Datalink A from SCANport Device (if enabled)
5 RO 32 bits Datalink A to SCANport Device (if enabled)
6 R/PW 32 bits Datalink A from SCANport Device (if enabled)
7 RO 32 bits Datalink B to SCANport Device (if enabled)

12 R/PW 32 bits Datalink D from SCANport Device (if enabled)
13 RO 32 bits Logic Status and Feedback
14 R/PW 32 bits 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.)
