I don't know where the problem is set,please help me check,Thank you .

Hi Ewen,

1. Thank you for your reply, it's working fine now. I want to run more than one iocs at the same times communication with css phoebus,is it the same port 5064? And just change the ioc name and port?

Yes, you normally always use the same CA port, 5064.

For procServ just change what script it executes to start the IOC, and the telnet port number.

Matt Newville wrote a nice Python script for starting our IOCs, which I have attached. 

To add a new IOC you just added it to the IOCLIST.  To start the IOC called 13BMD_XPS you just type

start_ioc 13BMD_XPS

That will also open a telnet connection to the correct port unless the “-s” or “–silent” option is used.

2. Is it can autorestart when the server restart?

start_ioc takes a “-b” or “–onboot” flag in which case it starts all IOCs that are flagged to start on boot. 

If the IOC is already running then typing

start_ioc 13BMD_XPS

will just telnet to the correct port.
