CompilerOmitsAttribute

Prevents ixc builder to create a member for specific group of output type (Shadow, Plain, Onliner).

note

This attribute must be declared in the PLC code to be effective during build process.

This example demonstrates how to prevent the ixc builder to compile specific property into specific output group.

// This will not compile to 'omitsInPlainString' member into respective 'Plain' type.
    {#ix-attr:[CompilerOmits(CompilerOmissionGroups.BuilderPlainer))]} 
    ommitsInPlainString : STRING(50) := 'THIS IS OMMITED IN PLAINER';     
    // This will not compile to 'ommitsInPlainAndShadowerInterfaceString' member into respective 'Plain' type and Shadow interface.
    {#ix-attr:[CompilerOmits(CompilerOmissionGroups.BuilderPlainer, CompilerOmissionGroups.BuilderShadowerInterface))]} 
    ommitsInPlainAndShadowerInterfaceString : STRING(50) := 'THIS IS OMMITED IN PLAINER';

Connector

Abstract base class provides implementation contract for the PLC connector and basic common underlying logic.

ConnectorAdapter

Provides basic abstractions for twin connectors.

ConnectorAdapterBuilder

Provides access to extension method for creating connector adapters.

ConnectorFactory

Provides abstraction for creation of Connector and value types (tags) for twin connector.

DummyConnector

Provides a connector without real target system connections.

DummyConnectorExtensions

Provides extensions for DummyConnector and DummyConnectorFactory.

DummyConnectorFactory

Dummy connector factory class. Serves as offline connector with no connection to a controller.

EnumeratorDiscriminatorAttribute

Attribute provides information about the member being treated as enum.

IPlainExtensions

Provides a series of extension methods to work with POCO objects.

ITwinController

Represents twin object for PLC controller.

IgnoreOnPocoOperation

This attribute will prevent R/W operation on on given member or type, when performing operation with POCO objects.

IgnoreReflectionAttribute

Indicates that the member should not be reflected within the ix framework.

PrimitiveAccessStatus

Provides information about access to a primitive item.

Indicates that the member should be access only once throughout the life time of the application during periodic reading. This attribute would be typically used for members that do not change value during the life time of the application.

ReadOnlyAttribute

Attribute allows to prevent writing to the members of twin connector.

ReadOnlyAttribute can be declared for member of a FB, GVL or STRUCT.

note

This attribute is typically defined in the declaration section of PLC block and then trans-piled by ixc builder.

warning

Use of ReadOnlyAttribute does not prevent the PLC program to write to the variable that declares this attribute.

This example demonstrates declaration of ReadOnlyAttribute on a member of a FB.

FUNCTION_BLOCK fbSomeReadOnlyMembers 
    VAR
        {#ix-attr:[ReadOnly()]]}
        _nonWrittableItem : BOOL;       // Member is readonly for .net application.
        {#ix-attr:[ReadOnly()]]}
        _nonWrittableFunctionBlock : fbNonWrittable; // Member and its members are readonly for the .net application.
    END_VAR
