Learn how to work with the simulator in S7-1200 and S7-1500 CPU models of Siemens PLC programming environment for simulation.
Simulator in S7-1200 and S7-1500 PLC?
Follow the below steps to test the logic in higher-end PLC CPU models of Siemens.
Note that you must choose version 4.0 and above to work with this CPU.
Step 1:
Open TIA Portal. Create a new project. Select the CPU as shown in the below window.
Choose CPU which has version 4.0 or above. Click “Add” to proceed.
Step 2:
Do add the signal module. Enter into the programming environment.
Consider the following example we want to test.
Step 3:
Click on the simulator icon as shown in the below window.
Step 4:
The following window will open which will compile the program. Click “load” to proceed.
Step 5:
Then following simulator window will open up.
Step 6:
Click on the icon as shown in the below image.
Step 7:
A new window will open. Here, we have to create a project so it can host a simulator.
Step 8:
Click on the project and create a new project. Give any name and hit “create” to proceed.
Step 9:
The following option will be added to this window as shown in below figure.
Expand “SIM table” and double click on “SIM table_1”.
Step 10:
SIM table is added to this window.
Step 11:
Click on icon represent in the red square. Add three tags to the list.
Step 12:
Tags that we have used in the program are added now.
Step 13:
Go back to the programming environment and test the logic.
Put simulator in start mode. Pressing START will turn ON the output.
Step 14:
Pressing STOP will turn OFF the output.
