Configure the I/O Modules Chapter 5
Appropriate RPI selection results in a system with maximum (best)
performance.
Every connection has a connection status tag.
If the RPI and CRTL for the network are set appropriately, then this
status tag must always remain LO. Monitor all connection status bits to
verify that they are not going HI intermittently due to timeouts.
Configuration Ownership – Reset Ownership
The connection between the owner and the Guard I/O™ module is based on
the following items:
• Guard I/O EtherNet/IP address
•Guard I/O safety network number
•GuardLogix slot number
• GuardLogix safety network number
• Path from GuardLogix controller to Guard I/O module
• Configuration signature
If any of these items change, the connection between the GuardLogix
controller and the Guard I/O module is lost, and the yellow yield in the project
tree appears. Reset ownership to re-establish the connection by using this
procedure.
1. Open the safety I/O module properties.
IMPORTANT Analyze each safety channel to determine what is appropriate. The default
timeout multiplier of 2 and network delay multiplier of 200 creates the
following:
• An input connection reaction time limit of four times the RPI.
• An output connection reaction limit of three times the RPI.
A safety administrator must approve changes to these parameters.
