When the SOA Gateway is activated by downloading the DeltaV application station, the first service to get activated is the Monitor service. This service supports the Gateway Administration application. The Monitor service default port is 49301.
Use the Windows netstat command to determine the port the other services are using and, if needed, find unused ports.
netstat -a -b
Look for instances that include the word LISTENING. For example, the Recipe Exchange service appears in the command output looking similar to:
TCP DVPROPLUS1:49201 DVPROPLUS1.DOMAIN:0 LISTENING 4088 [EmersonProcess.Web.Services.RecipeExchange.RExWindowsServiceHost.exe]
Depending on where you are running the netstat command, there may be instances of the service appearing in the output other than the port number (49201) shown above, but they will not include LISTENING so you can ignore them.
