ControlFunctionStateMachineType Definition – OPC UA for Laboratory & Analytical Device Standard (LADS)

7.6.2 ControlFunctionStateMachineType Definition

7.6.2.1 Overview

The ControlFunctionStateMachineType represents the state of a Function in a LADS Device. It uses the same StateTypes and TransitionTypes as its parent but specifies the additional Start Method to trigger state changes.

The ControlFunctionStateMachineType is formally defined in Table 89.

LADS ControlFunctionStateMachineType

Start starts a Function on the LADS Device.

7.6.2.2 Start

The Start Method starts a Function on the LADS Device.

The signature of this Method is specified below. Table 90 specifies its representation in the AddressSpace.

Signature

	Start()

7.6.2.3 StartWithTargetValue

The StartWithTargetValue Method starts a Function on the LADS Device with the target value as an argument.

Table 92 specify the Arguments and AddressSpace representation, respectively.

Signature

	StartWithTargetValue (
		[in]	Number	TargetValue)
