6.6Advanced Map Descriptor Examples

Example 1 : Filtering Data

You can direct the driver to filter the incoming messages so that data arrays are only updated for particular states. For example an incoming messge which reports a device in Ckt 1 to be in a FAULT state (Status:FAULT) will use the map descriptor ‘Ckt1_data03’ to store the data and the array DA_FAULTS1 will be updated. If however, the message reported an ALARM state (Status:ALARM) then the array DA_ALRMS1 would have been updated.

In fact, because the examples below provide a map descriptor where the data type is ‘Any’, each incoming message would update two data arrays. The DA_Status1 array would be updated by every single message and the other arrays would be updated depending on the state being reported in the message.

You would need another set of these map descriptors for any other circuit you are monitoring.

By using specific data types, the driver will only update the associated data arrays when the messages report a state that matches the data type.
