Port Reference

An Ignition server uses many ports to manage information between itself and other Ignition servers, OPC servers, devices, and other services such as SMTP and ERP servers. The following table describes the default ports an Ignition server may use for communication. Most are configurable and some of these ports may be on a computer other than the one Ignition is installed on (that is, if MySQL is installed on a different computer, the Ignition server will not be using port 3306). This is not a complete list of TCP ports, and there are a few UDP and broadcast ports in the list. Ignition will potentially use other ports if you are connecting to additional services or devices. Setting ports may be possible for some of the following, but will depend on their respective software.
