General Points

This tab is used to manage the I/O objects of a module, a field bus device or the memory and system objects of the PLC.

The following table summarizes the different functionalities according to the type of device associated with the tab:

Access Rules

To access this tab, the following conditions must be met:

  • The tab can be accessed from the configuration screen for the module, processor or bus device (it is located at the same level as the description tab).

  • The tab is accessible in offline and online mode.

Operating Rules

The main operating rules are as follows:

  • This tab can be used to create and associate variables, but not to delete them.

  • To delete a variable created by this tab, you must use the data editor.

  • Multiple presymbolization can only be used on compatible objects (of the same type).

  • For the processors, the tab only allows PLC objects to be displayed (variables cannot be associated).

  • The control loops built into the processor are regarded as module channels, and consequently, creation and presymbolization are possible.

  • It is possible to name a variable derived after symbolization.

    For example, if Counter_0 is a T_COUNT_STD type variable, the presymbolized counting value Counter_0.CUR_MEASURE can be renamed (Value_C0, for example).
