There are 3 ways to select a pre-defined Input or Output assembly
object:
1. Use the PLC Explicit communications to write directly to the
Control Supervisor. (See page 43 in DeviceNet User Guide Issue
1.) The relevant attributes are 100 (Output) and 101 (Input).
2. Use the Class Instance Editor within RSNetworx to modify the
Control Supervisor directly yourself. Refer to page 43 to check the
supported services for Unidrive DeviceNet interface.
3.
Double-click on a node to go on-line to it, and look under the group
"DeviceNet Config". In this group, you will find the attributes
"Polled Input Assembly" and "Polled Output Assembly". Update
with the appropriate value.
NOTE
The parameter mapping of the pre-defined DeviceNet objects CANNOT
be changed.
