The data conversion capabilities of the binary records bi, bo, mbbi, mbbo, mbbiDirect, mbboDirect are supported with two dtypes "opc" and "opcRaw" as described in the Record Reference Manual for the "Soft Channel" and "Raw Soft Channel" types.

Microsoft Visual Studio may be used. You need to run make before you can use MS Visual Studio. On the other hand, OPC servers can have huge name lengths for those items. So a map file may be defined to map the long OPC server names to short names suited for the record's link field.

The device support accepts all but "Passive". Due to the update facilities of the OPC group it is not reasonable to define a scan rate faster than the update rate of the group. They will be updated to the new value if it is changed on the OPC server by any other way e. Nevertheless, if the OPC server gets a new value for the OPC item the record will be processed to update the value, send monitors, check for limits, set severities and process forward links.

In this case a caput will not be recognized by the PLC! The behaviour of the record is listed below and is according to the desccription of the raw data types in the Record Reference Manual.

The resulting timestamp is not protected against backwards movement either.
