InterfaceLocal

An InterfaceLocal is the private internal container of a controller: its local variables, message definitions, function blocks, interlock definitions, simulation and helper methods - everything not visible from outside. It is the internal member of the controller's public / per-instance / local interface triad.

FunctionBlock

A FunctionBlock is an IEC function-block instance inside a controller, wrapping vendor or library logic. It references a function-block type from a datatype library that defines its inputs, outputs and internal state. In driver controllers it is effectively the driver implementation.

FunctionBlockModel

RecordType

A RecordType is a structured (struct) datatype defined in a DatatypeLibrary, composed of named fields. It defines a shared data shape that many controller variables, such as configuration or recipe structures, can be typed by.

FieldComplex

A FieldComplex is a single field of a RecordType. Its type may be an IEC base type, an enumeration, or a nested record.
