Normal read Map Descriptor. Note RDBC function, Data_Type and Address specification.

COS_Poller Map Descriptor. This only specifies the Function, Node and Scan_Interval.

COS_Read Map Descriptor sets point type the same as normal read Map Descriptor. Optional scan_interval.

Release function used in conjunction with wrbx. If the Data Array value specified in this Map Descriptor is changed, then a Release command is sent to the specified point.

Note:

To get change of state (COS) reports from an analog port, the warning/alarm levels need to be configured. If the alarm/warning values are not known, then it would be better to configure an RDBC Map Descriptor which reads the analog input directly. Limits will then not be required.
