INGEAR.NET.GELink Classes, Methods and Properties Controller Class - A class that handles the communications with the PLCs. EventCode Class - Enumerates the different codes used by the Controller Class events. ResultCode Class - Enumerates the different codes used to define the results of the methods for the Controller, Tag, and TagGroup classes. Tag Class - A class that contains information about the tags used by the Controller Class to communicate with the AB PLCs. TagGroup Class - A class that is a collection of Tags (see Tag Class) CONTROLLER Class - A class that handles the communications with the PLCs. Properties ErrorCode Returns the last recorded error code as an integer for the Controller Class ErrorString Returns the last recorded error as a descriptive error for the Controller Class. IPAddress Gets or sets the IP Address IsConnected Returns TRUE if there is a current connection with the PLC MyObject Gets or set a user-defined object that is associated with this Controller instance. Path Gets or sets the routing path for this PLC. This property is provided to compatibility with other INGEAR.NET products and has no meaning for the GELink product. Timeout Gets or sets the amount of time (in milliseconds) that the instance waits for a completed connection to the PLC. Version Gets the current version of the GELink component. Methods Connect Attempts a connection to the PLC. CreateNewGroup Creates a new instance of IGroup (see Interfaces) CreateNewTag Creates a new instance of ITag (see Interfaces) Disconnect Disconnects the instance from the PLC. GroupRead Performs a Read of a TagGroup (see TagGroup class) GroupWrite Performs a Write of a TagGroup (see TagGroup class) ReadTag Performs a Read of a Tag (see Tag class) WriteTag Peforms a Write of a Tag (see Tag class) To Top EVENTCODE Class - Enumerates the different codes used by the Controller Class events. To Top RESULTCODE Class - Enumerates the different codes used to define the results of the methods for the Controller, Tag, and TagGroup classes. To Top TAG Class - A class that contains information about the tags used by the Controller Class to communicate with the PLC. Properties Active Sets / Gets the active state of the tag Controller Sets / Gets the instance of a Controller class DataType Sets / Gets data type for PLC register values ErrorCode Returns the error code for the last PLC access for the Tag instance ErrorString Returns the error code for the last PLC access for the Tag instance as a string Length Sets / Gets the number items to read or write from the PLC MyObject Sets / Gets user defined object Name Sets / Gets the PLC register address NetType Sets / Gets the .NET Type of the PLC value Now Executes immediate read / write operation QualityCode Returns the quality state of the last PLC access operation for the Tag instance QualityString Returns the quality state of the last PLC access operation for the Tag instance TimeStamp Gets time stamp for last successful PLC access operation for the Tag instance Value Sets / Gets the PLC register value Events Changed Fires when the value of the tag has changed. To Top TAGGROUP Class - A class that is a collection of Tags (see Tag Class above). Properties Active Gets / Sets activate state of group Controller Sets / Gets instance of Controller class associated with TagGroup Count Gets the number to Tag class instances in the group ErrorCode Gets numeric value for last error encounted by group ErrorString Gets numeric value for last error encounted by group MyObject User-defined object associated with instance of TagGroup Now Preforms an immediate read of all ITag in the Group Tags Gets list of Tag classes in the group Methods AddTag Adds instance of Tag class (or array of Tag classes) to TagGroup collection Clear Removes all Tag objects in TagGroup collection CreateNewTag Creates new instance of ITag RemoveTag Removes specific instance of Tag class from TagGroup To Top Sample code for various platforms can be found at our Code Center.
