8.41.1 Overview

The TMCStateMachineType describes the finite state machine of a complex automation item including a machine module, an equipment module and a control module.

The TMCStateMachineType is modelled and inherits from the PackMLBaseStateMachineType defined in OPC 30050 - UA for PackML (OMAC) v1.01 and provides additional TMCMachineStateMachineType and transition information by means of guards implemented by the BooleanGuardVariableType.

The TMCStateMachineType is formally defined in the following table.
