Creating a new simple data type

As a name for the new simple datatype enter Temperature sensor.
Select UINT as the basic datatype.

With Finish the datatype is created and now is available in the list of datatypes.

Select the datatype Temperature sensor in the list.

In the property window, the properties of the data type Temperature sensor are now displayed and we can make all the necessary changes.

Change the properties Unit, Decimals, Linear value adjustment and Value range PLC of the datatype as shown in the illustration above.

Value range PLC	digital value from the temperature sensor, in this case 16 bit resolution in the PLC
Value adjustment linear	analog value from temperature sensort, according to our setting, this corresponds to Min. 0,00 ºC / Max. 655,35 ºC in the project.

We now will define limits for the datatype Temperature sensor.

Open the section Limits in the properties window.
Select the entry <Limit new>.

A new section with the name Limit[1] is created.

Change the properties of the limit as shown in the illustration above.

Example

Create three more limits for the datatype Temperature sensor:
Limit 2: 100; MIN; dark blue; no alarm
Limit 3: 400; MAX; dark red; no alarm
Limit 4: 500; MAX; light red; alarm
