Solution
SystemLink™ requires the following network ports to be open on the server:
- Port 80 (for insecure HTTP)
- Port 443 (for HTTPS)
- Ports 4505-4506 (for Salt Service)
- Port 5672 (for RabbitMQ — required to support legacy client communications; disabled by default)
- Ports 2343, 2809 and 59110-59210 (required for SystemLink™ TDM modules' functionality only)
- Ports 59100-59110 (for LogosXT — required for OPC UA connectivity only)
The SystemLink™ installation process manages port configuration, so generally, no additional steps are required. However, some anti-virus or IT security software can block the opening of these ports. SystemLink™ does not open ports on the client device(s).
