6.1.13
Media Redundancy
This value shows the current state of the active media redundancy protocol. DLR can be active only
when EtherNet/IP is the active protocol and MRP when PROFINET has been selected.
The values are mapped in the following way:
•
0 = No ring protocol
•
0# = Ring protocol initializing
•
1# = Ring protocol status ok
•
2# = Ring protocol failure
•
#1-#3 = MPR
•
#4-#6 = DLR
The value definitions and how they map to media redundancy specification states (in MRP MRC state
machine and in DLR announce based node state machine) are defined in table below.
6.1.14
SNTP settings
The SNTP settings are used to enable Simple Network Time Protocol for updating date and time to
drive from network.
