This might not apply to your case, but if you open a SIMIT project with the VC coupling already configured, you need to open the VC coupling in SIMIT before trying to connect from VC.
This is because opening the coupling’s editor in SIMIT also initializes the server that VC connects to.
Looks like I only have problems with an external systen (VM other notebook). Locally, of course I can make the connection.
I asked support for help. I will give updates here.
Can you try with the firewall of the VM dissabled?
Maybe the firewall is blocking the traffic to the simit port.
If it works when you dissable your firewall. You can edit it to allow traffic to the correct port and enable it again
You should ask Siemens…
If you are a Siemens Solution Partner, you can get the Simit software for a favorable price. I cant tell you the exact price but it is below 5.000 euro + a yearly subscription (with upgrades) for another 1500.
