Hello Dirk,

I've done what you suggested. But I can't read passive records 2 values.

23 bytes "... 026 027 025 025 026"

The timeout suggests that there is something wrong with your terminator

settings. StreamDevice and asynDriver are waiting for more input but the

device has stopped sending. I see no "\r\n" in the read debug output.

Does the device send any terminator?

[root@105 ipThermo]# caput M:TEMP1 1

[root@105 ipThermo]# caget M:TEMP6

I defined DTYP as "Raw Soft Channel".

    Hello,

    I have a self-produced thermocouple and I connect to this device by RS 232.
    I want to read 6 different integers when I send"MEASC"  command to the
    device.

    in thermo.proto file, if I define %s, I can read all data by stringin.

    MEASC{
          out"MEASC";
          in"%s";
    }

    Example:
    2013/10/07 10:59:53.633192.168.1.198:9001  <http://192.168.1.198:9001>  <http://192.168.1.198:9001>
    write 6
    MEASC\n
    2013/10/07 10:59:53.647192.168.1.198:9001  <http://192.168.1.198:9001>  <http://192.168.1.198:9001>
    read 8
    029 030 029 028 028 028

    But I want to take all 6 datas in integer format. I search the
    streamdevice documentation and I found the following line.

There several possibilities to do this.

    MEASC{
          out"MEASC";
          array_in {separator="  "; in"%d";}
    }

    But it doesn't work. I got the following error.

No that does not work. What you wanted to do is:
MEASC{
     separator="  ";
     out"MEASC";
     in"%d";
}

But then you get an array of 6 values. Maybe you want to have the 6
values in separate records. You can do this using redirected input:

MEASC{
     out"MEASC";

in "%d %(\1:TEMP2)d %(\1:TEMP3)d %(\1:TEMP4)d %(\1:TEMP5)d %(\1:TEMP6)d";

}

Called from a record like this:
record (ai,"$(P):TEMP1") {
     field (DTYP,"stream)
     field (INP,"@thermo.proto MEASC($(P)) $(PORT)")
}

And 5 passive records like this:
record (ai,"$(P):TEMP2") {
}
record (ai,"$(P):TEMP3") {
}
record (ai,"$(P):TEMP4") {
}
record (ai,"$(P):TEMP5") {
}
record (ai,"$(P):TEMP5") {
}

Note that the 5 passive records have no "stream" support (in fact they
use "Soft Channel" or if you wish you can use "Raw Soft Channel").
