First, you appear to have an error in your protocol file because you are getting this error:

2015/12/28 16:21:42.753 _main_ devNozzleExchange.proto line 30: in variable assignment 'in = ...'
2015/12/28 16:21:42.753 _main_ devNozzleExchange.proto line 29: in protocol 'getrobotnozzleoffsta'
2015/12/28 16:21:42.753 _main_ while reading protocol 'GetCryoBackSta' for 'BL5C:NOZZLE:GetCryoBackS

However you did not send us the complete protocol file, you only sent the part for GetRemoteSta.

Please send the entire protocol file.

Please also send the entire output as the IOC starts up. We need to see any errors that occur before and after iocInit.

It appears to me that it is sending that command correctly.  The asynTrace output shows that it is sending the string you want.

However, it is not receiving the reply you expect.  It is receiving "ER=1\r\n" not "?501\r\n" for example.

You need to read the manual for the device and see what the ER=1 response means.  It looks like it is probably an error code.

The best way to debug this kind of thing is to either to:

- Stop the IOC and telnet directly to the device.  Send the commands manual and look at the response.

- Run the IOC but set those records to Passive rather than 0.2 second scan.  Load an asynRecord for that PORT and open the asynOctet.adl screen.

- Send commands from the asyn record and look at the response.

Subject: Nozzle Exchange Command Error...

Hello.

i'm in trouble with Nozzle Exchange Device..

-------------------------------
devNozzleExchange.proto

    field(ZNAM, "Local")

----------------------------------------
Nozzle Device Description
------------------------------
-Local/Remote Switch status request

 state request = "! + 50 + SWS +Cr/Lf"
 return state = "? + 50 + x1 + Cr/Lf" ( 6 bite ascii receive)
 x1 = 0 : Local , x1 = 1 : Remote

------------------------------------------------------
i think the send command is wrong.

i want to send ascii code(convert  out "!50SWS" to ascii code)

how can i do it?

is it  .proto function?

is it  another solution?
