Online test

The online test and simulation modes allow you to monitor the execution of your circuit program and how it reacts to the various input states.

For LOGO!Soft Comfort V8.3 and later versions, if LOGO! TDE device is connected with LOGO! Base Module, when you perform an online test for LOGO! Base Module, messages shown on the connected TDE device are displayed.

Note

If LOGO! Base Module is connected with multiple LOGO! TDE devices, messages of only one LOGO! TDE are displayed and you can select which LOGO! TDE to display.

Difference from simulation mode

In simulation mode you execute your circuit program on the PC. To do so, you do not require a LOGO!. You can preset the status of inputs on the PC.

During an online test, LOGO! executes the circuit program and you can monitor this "work" of LOGO!. The status of the inputs corresponds with the actual states at LOGO! inputs.

Prerequisite for an online test

You must link your PC to a LOGO!. LOGO!Soft Comfort uses the interface you specified in Tools → Transfer to link to LOGO!.

You can test a circuit program in either FBD or LAD format and you must transfer it to LOGO! for the online test.

The circuit programs in LOGO!Soft Comfort and on LOGO! must be identical. Upload the program from LOGO! to your PC, or download the program from your PC to LOGO! if necessary.

You can monitor the parameters of up to 30 blocks. The number of blocks you can monitor simultaneously decreases when you monitor blocks that contain a high number of parameters (for example, analog SFBs).

Starting the online test

Click the online test icon in the programming toolbar.

If LOGO! is in STOP, start it with the start button.

Result: LOGO! executes your circuit program.

Switching LOGO! to STOP

If you want to stop LOGO! via LOGO!Soft Comfort, click the stop icon .

Devices of the 0BA4 series and later support online tests.
