You have to provide different 'port names' for the devices.  e.g.:
drvAsynIPPortConfigure "terminalA", "10.30.9.28:4016"
drvAsynIPPortConfigure "terminalB", "10.30.9.28:4015"
drvAsynIPPortConfigure "terminalC", "10.30.9.28:4014"
drvAsynIPPortConfigure "terminalD", "10.30.9.28:4013"

I would further suggest that you make the port names something that reflects the equipment attached to the port:
drvAsynIPPortConfigure "Voltmeter", "10.30.9.28:4016"
drvAsynIPPortConfigure "Power Supply 1", "10.30.9.28:4015"
drvAsynIPPortConfigure "Power Supply 2", "10.30.9.28:4014"
drvAsynIPPortConfigure "Current Source", "10.30.9.28:4013"

hi:

I am using streamDevice driver to drive several same devices, they connect to different ports. If I modifiy the example.cmd like this:
drvAsynIPPortConfigure "terminal", "10.30.9.28:4016"
drvAsynIPPortConfigure "terminal", "10.30.9.28:4015"
drvAsynIPPortConfigure "terminal", "10.30.9.28:4014"
drvAsynIPPortConfigure "terminal", "10.30.9.28:4013"

  when ioc runs, it shows:
drvAsynIPPortConfigure "terminal", "10.30.9.28:4016"
drvAsynIPPortConfigure "terminal", "10.30.9.28:4015"
asynCommon:registerDriver terminal already registered
drvAsynIPPortConfigure: Can't register myself.
....

If I load only one device, all is ok. Can I load several same devices in one EPICS application? Or need I seperate them to four applications?

Thanks a lot for any help.

Best wishes
