Re: how to load several same devices in stream

[Eric Norum <norume@aps.anl.gov>]

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"
