2.3.17 Interval for Freeze
0 to 65535
Freeze Start Type and Interval for Freeze are used if Mode A operation is to be
used for the counter freeze operation. If they are not used, the module will
operate in Mode D.
2.3.18 Set Priority Queues
Yes or No
This section defines priority queues for the module. The data types that can
return events can be assigned priorities so that events of data types will be
returned before other data types. This may cause events to be lost as the event
buffers for low priority queues may overflow. If this feature is utilized, each data
type must be assigned a unique index from 0 to 6. The lower the index, the
higher the priority (0=highest priority).
M_SP_Na Priority : 1 #Unique index for this data type in queue (0-5)
M_DP_Na Priority : 0 #Unique index for this data type in queue (0-5)
M_ST_Na Priority : 5 #Unique index for this data type in queue (0-5)
M_ME_Na Priority : 4 #Unique index for this data type in queue (0-5)
M_ME_NB Priority : 3 #Unique index for this data type in queue (0-5)
M_ME_NC Priority : 2 #Unique index for this data type in queue (0-5)
M_IT_Na Priority : 6 #Unique index for this data type in queue (0-5)
Each of the ASDUs affected by this feature must be assigned a unique priority
index from 0 to 6. Events of the ASDU with a priority of 0 will always be reported
before any others when they are present.
For more information, refer to Event Priority (page 117).
2.3.19 Cyclic Set IV Time
Minimum 3 times larger than IV Check Delay Time parameter
0 to disable
The Cyclic Set IV Time parameter determines how frequently the IV Checks will
be performed. If the IV bit is ON for a number of times given by the IV Fail Count
(page 32) parameter, the module will consider the point as invalid.
If the IV Fail Count parameter is zero, the feature will be disabled.
For more information on using this feature, refer to Using Monitor Points (page
97).
2.3.20 IV Check Delay Time
Value in Seconds
This feature allows the application to set the invalid (IV) quality bit of the protocol
for all the monitored ASDU types supported. The Cyclic Set IV Time parameter
must be at least 3 times larger than the IV Check Delay Time.
