In addition to the usual data fields that you would expect to find on a Geo SCADA Expert Point object, a FloBoss Digital Point object also has the following data fields, which are listed in the Geo SCADA Expert Database Schema (see Schema View). The name in bold at the start of each entry is also the OPC tag name.
- CurrentValueAsBoolArray. If the point refers to a TLP that holds a bitfield (BIN) value, this tag will be populated with the value of the point as an array of Boolean values. This provides a convenient way to access the values of the individual bits values in the bitfield without script. You can use an expression with array referencing to get the value of a single bit. For example, to access the least significant bit, write PointName.CurrentValueAsBoolArray[0] in an expression. To get the next least significant bit, write PointName.CurrentValueAsBoolArray[1] and so on. The CurrentValueAsBoolArray tag has no meaning for TLPs that do not refer to a bitfield value.
- LastError. This field contains a string that describes the last error on the point. For example, a ROC protocol error for a write request to a read only value.
- LastErrorTime. The timestamp for the LastError field. The timestamp is generated by the driver and as such is in the same time zone as the server.
