Server Processes

After you have configured computers, network addresses and clusters, you can add server processes and assign them to clusters and computers. Primary and standby alarms, reports, trends, and I/O server processes can be added in Plant SCADA Studio's Topology activity.
Default Ports
Each server process has a unique default port assigned to it. This default port may only be used with that type of server process. Attempting to use a default port on another type of server process will result in a compilation error message:
"Invalid port number (2080-2088,2073,3073,5482,20222 are reserved)."
The following table lists the default port numbers and their associated server process type.
|
Default Port |
Server Process Type |
|---|---|
|
2073 |
CtAPI Note: Plant SCADA will open ports 2073 and 3073 when a CtAPI application is running. If the connection to a client is fully encrypted ("mixed mode" is not enabled), only port 3073 will be used. See Secure the Connection from a Remote CtAPI Application. |
|
2080 |
Alarm server. |
|
2082 |
I/O server. |
|
2084 |
Reports server. |
|
2085 |
Trends server. |
|
2087 |
System services process. |
|
2088 |
Time synchronization port. |
|
3073 |
CtAPI Note: Plant SCADA will open ports 2073 and 3073 when a CtAPI application is running. If the connection to a client is fully encrypted ("mixed mode" is not enabled), only port 3073 will be used. See Secure the Connection from a Remote CtAPI Application. |
|
5482 |
Alarm server database port. This port is only used between the alarm server and its backend database on the same computer. It does not require external access. |
|
20222 |
Required if Plant SCADA is configured to run as an ODBC server (see Use Plant SCADA as an ODBC Server). |
Note: Ports 2074 - 2079 were reserved in earlier versions for legacy connections. These ports are no longer used.
For a list of the ports used by Plant SCADA runtime, see Firewall Settings and Plant SCADA.
