3.7.1
Commissioning the technology object
A graphic display of the block in the commissioning editor helps you with commissioning and
the function test for the technology object. You can change specific parameters of the
High_Speed_Counter instruction in CPU/IM online mode and monitor their effects.
Requirements
● There is an online connection between STEP 7 (TIA Portal) and the CPU.
● The CPU is in RUN.
● The corresponding High_Speed_Counter instruction is called cyclically from the user
program.
● The parameters of the technology object are not overwritten by the user program.
Procedure
To open the commissioning editor of a technology object and to simulate a parameter value
change, follow these steps:
1. Open the "Technology objects" folder in the project tree.
2. Open the High_Speed_Counter technology object in the project tree.
3. Double-click on the "Commissioning" object.
The functions for commissioning the High_Speed_Counter technology object are
displayed.
4. In the commissioning dialog, click on the "Monitor all" button.
The parameters (online values) of the High_Speed_Counter technology object are loaded
and displayed.
5. If the parameter you want to change has a text box, enter the new value there.
6. Select the check box of the parameter.
The new parameter value becomes effective and the effects of the change are simulated.
Online mode
In online mode, you can modify the following parameters to test the technology object
function:
● New counter value (NewCountValue)
● New high counting limit (NewUpperLimit)
● New low counting limit (NewLowerLimit)
● New comparison value 0 (NewReferenceValue0 or NewReferenceValue0_M)
● New comparison value 1 (NewReferenceValue1 or NewReferenceValue1_M)
