However, when I click on the simulation button, a warning triangle appears in the I/O field (see Picture 1). Additionally, the buttons in the figure are not working. I’ve tried everything I found on the forum, but it doesn’t work. In the attachment, I have included the installed versions. Attachment Screenshot (4).png (219 Downloads)

Could you please confirm if you are also simulating the PLC or if the PLC HW is real?
	A rating will be well appreciated.

This will allow you to see the alerts generated by the system. There will probably be some that are related to the communication problem. Knowing what they are will help you troubleshoot the problem. Kind regards Stefan
