5.6.25 IV Fail Count
1 to 65535 seconds, or 0 to disable Invalid Bit Monitoring
This parameter sets the number of successive IV Bit check failures which must
occur before the data from a IEC database monitor point will be reported to the
remote Client as invalid data.
An IV Bit Check Failure occurs when the IV Bit value in the module database is
set ON {when it contains a value of one (1)} at the time an IV Bit Check is
performed. IV Bit Check failures are counted and held in separate IV Bit Check
Failure accumulators for each IEC monitor point configured for validity checking.
If the value in any point's failure accumulator becomes equal to the value set in
this IV FAIL COUNT parameter, the module will consider data from this point as
invalid and report to the Client this invalid status, along with the point's data
value.
Setting this parameter to zero (0) will disable data validity checking.
5.6.26 Scan Events
0 = NO SCANNING or 1 = SCAN FOR EVENTS
Separate parameters exist for multiple point types. Defines whether events of this
point type will be generated by the module. If set to zero (0) for NO SCANNING,
then events will not be generated. If set to SCAN FOR EVENTS, events will be
scanned and generated on data change.
