Static ring port
Relevant only when the HRP Manager role is selected and the HRP manager role was
adopted.
The port that is active in the ring is specified here.
Isolated ring port
Relevant only when the HRP Manager role is selected and the HRP manager role was
adopted.
The port that closes the ring but via which no communication takes place is specified here.
Redundancy Role
Here, you can see which role the module has actually adopted in the ring.
Redundancy Manager State
Relevant only if the HRP manager or MRP manager role was adopted.
● Passive:
The IE switch is operating as redundancy manager and has opened the ring; in other
words, the line of switches connected to the ring ports is operating problem free.
● Active:
The IE switch is operating as redundancy manager and has closed the ring; in other
words, the line of switches connected to the ring ports has been interrupted. Fault
situation. The redundancy manager switches the connection between its ring ports
through and therefore restores a continuous bus topology.
Number of State Changes
Relevant only when the redundancy role HRP manager or MRP manager was adopted.
This shows how often the redundancy manager switched to the alternative path due to an
interruption in the ring since the device was turned on.
Maximum delay (ms)
Relevant only when the HRP manager or MRP manager role was adopted.
This shows how long a test frame was delayed. (Test frames are placed on the ring to detect
interruptions in the ring.) For reliable functioning of the network, values < 20 ms are
necessary.
Note
The standby function always requires an activated HRP client. If the standby manager is
activated, the following message is displayed if an attempt is made to turn off ring
redundancy or to change to "Redundancy Manager":
Cannot disable "Redundancy" if "Standby Manager" is enabled.
Note
When the devices ship, the default ring ports are set, see Appendix Default ring ports
(Page 177).
