If the IV bit field is absent or set to 0, the invalid quality state for the point will
always be reported as valid.
If a database bit address (1 to 64000) is present, the application may consider
the point with an invalid flag if the previous logic checks the iv bit as 1 during
consecutive IV Check Delay scans. The iv bits would have to be reset to 0 to set
the point to valid state.
The IV DB bit defined for each point can be unique or many points may share the
same bit. The last case could be used when the points on an I/O module are to
be considered as one set. In this case only a single bit is required. For a point
that is the result of a computation, the valid quality state could be set for each
point individually.
Monitor Data Transfer
Typically, you should properly configure the group code for each monitor point to
define how the master will poll for the point. The group codes are defined as
follows:
The Group parameter is defined as follows:
