Appendix B CIP Information
CIP Explicit Connection
Behavior
The ArmorStart LT allows run, jog and user outputs to be driven by connected
explicit messages when no I/O connection exists, or when a I/O connection
exists in the idle state. a single EtherNet/IP Class 3 explicit connection will be
allowed to send “explicit control” messages via an “Active Explicit” connection.
An EtherNet/IP Class 3 explicit connection becomes the “explicit control”
connection when it becomes the first EtherNet/IP Class 3 explicit connection to
send a “set” service to one of the following:
• The “value” attribute of any Discrete Output Point (DOP) instance (Class
Code 0x09).
• The “data” attribute of any output (consumed) Assembly instance (Class
Code 0x04).
• Attribute 3 or 4 of the Control Supervisor Object (Class Code 0x29).
EDS Files
The information contained in the EDS (Electronic Data Sheet) files for
ArmorStart LT EtherNet/IP can be extracted via the network.
