OPC-30000 – OPC UA for Programmable Logic Controllers based on IEC61131-3

7.5 CtrlFunctionBlockType ObjectType Definition

CtrlFunctionBlockType ObjectType Definition This ObjectType defines the representation of a Ctrl Function Blocks of a programmable Controller system in an OPC UA Address Space . It is derived from CtrlProgramOrganizationUnitType ... components in addition to the components of the base type. Figure 19 shows the CtrlFunctionBlockType . It is formally defined in Table 17 . Figure 19 - CtrlFunctionBlockType Overview The CtrlFunctionBlock ObjectType

4.3 Introductory Example

executed. These data are represented by OPC UA ObjectTypes derived from the ObjectType CtrlFunctionBlockType (see Figure 11 ). To start, IEC 61131-3 IEC 61131-3 requires a Ctrl Function Block ... shown in Figure 11 . The ObjectType CTU_INT is a subtype of the ObjectType CtrlFunctionBlockType . Its components are defined by instance declaration and referenced by HasInputVar , HasLocalVar , and HasOutputVar References
