Example - General Interrogation
Assume the following data points are configured for General Interrogation as follows.
This feature allows you to separate the points into different groups according to the
priority level that they should be reported to the Client. In the example above, points
100 and 101 would be returned with a General Interrogation for Group 1 and point
102 would be returned with a General Interrogation for Group 2.
Counter Points
There are four modes of acquisition of integrated totals (M_IT_NA points) defined by
the protocol specification. The actual values may be memorized (copied) periodically
to frozen values by a freeze command received from the Client or initiated locally
within the gateway.
The gateway supports the following two of the four possible modes:
Mode A - Local freeze with spontaneous transmission
Mode D - Counter interrogation commands from the Client initiate the freeze
operation and the frozen values are reported spontaneously.
