NOTICE

Note that manually creating another instance of the device object can lead to malfunctions.

On this tab of the generic device editor, "objects" are listed that allow for access to the device from the IEC application. In online mode, this is used as the monitoring view.

For devices for which a function block instance is created implicitly, at least this instance is listed as an object here in the table. This instance can be used, for example, in order to restart a bus or to query information from the application. The device type determines whether this kind of device instance is available and which access options it has. See the help for the special device configuration.

Instances of function blocks that are linked with inputs or outputs of the device are also displayed here. The mapping of a function block to a channel is defined in the “<device name> I/O Mapping” tab. The _cds_icon_goto_definition.png “Go to Instance” command takes you directly to the affected object from there.

In addition, you can create more objects in the table here that are not yet linked with a device channel.

In online mode, you can use the table of IEC objects as a monitoring view. It also shows the current value, the address, and the comment for the function block variable at the channel. Finally, it provides the capability of writing and forcing values.

_cds_icon_add_fb.png “Add”

_cds_icon_edit_ug.png “Modify”

Opens the “Select Function Block” dialog for creating a new instance or for editing the instance selected in the table.

_cds_icon_delete.png: “Delete”

Deletes the selected entry

_cds_icon_goto_definition.png “Go to Variable”

Jumps from the selected entry directly to the corresponding mapping on the “<device name> I/O Mapping” tab.

“Variable”

The object name comprises the device name and the function block name. Example: ‎EL2004_Relay‎. Changing the device name has an immediate effect. The part of the name after the device name is editable here.

“Mapping”

Mapping type, as in the “<device name> I/O Mapping” tab

“Type”

Data type: Here it is the name of the function block.

“Value”

“Prepared value”

“Address”

“Comment”

In online mode only:

Display of the current value, the address, and the comment for the variable at the channel

Moreover, the option of specifying a value for writing or forcing the variable.
