PLC simulator fits the Cyber Security requirements.
These two rules are applied:
PLC Simulator Only Starts with an Application Inside
The PLC Simulator Option Panel supplies a new check box Use default application to start simulator (enforce security) and a new field to give the application path.
If Use default application to start simulator (enforce security) box is checked, an application with password should be accessible by the path given in the field, this is the default option.
If the option is unchecked, a message is displayed to inform that the PLC Simulator use is not secured on its 502 Port.
At first start of PLC Simulator, the box is checked but the path is empty. A popup message informs that:
-
A valid Control Expert application is mandatory to start PLC Simulator.
-
To enforce security, it is necessary to use an Application Password.
NOTE: Password protected application is necessary to enforce security on Ethernet port of computer which is by default port 502.
When PLC Simulator is started from Control Expert (menu PLC → Connect) or from Windows menus with Use default application to start simulator (enforce security) box checked:
-
If there is no application with password in the PLC simulator or application path is not valid, the Simulator Panel Options windows pops up and PLC simulator will not start unless a valid path is set or the option is unchecked.
-
If application path is valid, the PLC simulator starts, without displaying the option panel.

In Monitoring mode the PLC → Transfer Project from PLC option is grayed. The related icon is grayed too.
As a result, the PLC Project from PLC simulator cannot be uploaded.
