Creating a new simple variable

In the project manager, activate the context menu of the entry Variables by a right click.
Select the menu entry Variable new.

The dialog for creating variables opens now.

As a name enter Temp.
Choose the driver S7TCP32 - S7 TCP-IP
Select Ext. datablock as the driver object type.
Select the datatype Temperature sensor.

With these settings, you would create a single variable. For creating multiple variables of the same type, some changes in the Array Settings are necessary.

Set the array dimensions 1 and 2 both to the value 2.
Confirm the settings with Finish.

The variables now are added to the variable list in the detail view of the project manager. All properties of our datatype Temperature sensor are pre-defined in the variables. The properties of the selected variable can be checked and changed in the properties window.

As we changed the array dimensions, not only one but four variables have been created. With our settings, these variables automatically get their addresses, i.e. we only have to define a start offset. zenon calculates the remaining addresses automatically.

Open the section Variables.
Select the entry Temp.
In the section Addressing set the property Start offset to the value 11.

This results in the following addresses:

Temp[1,1]	Offset 11
Temp[1.2]	Offset 13
Temp[2.1]	Offset 15
Temp[2.2]	Offset 17

The property last used offset accordingly reads: 18/7 (Offset 18 / Bit 7).

The variable list in the detail view of the project manager now should have the following entries.

Info

Always use logical names for the process variables in order to keep a better overview.
