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.
Table 22. Values for MPR
Value Name Description Standard state
0 None • No active ring protocol -
1 MRP (Ring) Init • Protocol is initializing Power up
11 MRP (Ring) Ok
• Ring ports are ok
• MRP_Test frames are received from both ports
PT_IDLE
21 MRP (Ring) Fault
• One of the ring ports have a failure
• Transitioning from one state to another
• MRP_Test frames are not received from both
ports
PT_IDLE,
DE_IDLE, DE, PT
22
MRP (Ring)
Stopped

14 DLR (Ring) Ok • Ring is closed and without fault NORMAL_STATE
24 DLR (Ring) Fault • Ring is open because of a ring failure FAULT_STATE
25
DLR (Ring)
Stopped
• DLR protocol has transitioned back to
