Programming the VLC-2-EIP
3.1 Servo objects
Servo objects are parameters and variables that are used to perform control and monitoring of
the VLC-2-EIP. From its update behaviour perspective, there are two servo object types in VLC-
2-EIP:
• Acyclic: updated upon request, used for servo configuration purposes.
• Cyclic: updated periodically, manipulated and monitored by a motion program executed
by the Ethernet/IP master.
3.1.1 Acyclic servo objects
Table 3.1 presents the acyclic servo objects of the VLC-2-EIP that are accessible through explicit
messaging set and get services. All of the objects have an explicit message instance ID of 1.
Objects with class IDs 0x68, 0x6A, 0x6B and 0x6C are standard ones that are also found in VLC-
25-07, therefore, explanations on their usage are available in the VLC-25-07 user manual.
