RE: Streams Support for Varian Dual

[Mark Rivers via Tech-talk <tech-talk@aps.anl.gov>]

Hi Heinz,

Thanks for sending that.  I believe these protocols are actually incorrect:

wsetpt1 { out "#\$1" "71%0.1E"; in ">\$1" "71";    }
wsetpt2 { out "#\$1" "72%0.1E"; in ">\$1" "72";    }
whvpwr  { out "#\$1" "30%1b";   in ">\$1" "00";    }

Those "set" commands actually only return an ACK character, they do not return the string in the protocol.  It does not generate an error message but it does generate a timeout.  The new protocol file in epics-modules/ip just looks for the ACK and does not timeout.

Thanks,
Mark

Hello, Mark,

this is the protocol file Ralph was talking about. We have that in the field:

epics@fel-aes:~/FHI/IOCVAC/IOCVACApp/Db$ more multigauge.proto # MultiGauge Compatible protocol for the Varian Dual Controller # Pete Owens 22-1-02 # Ralph Lange 19-08-11

terminator   = CR;
replytimeout = 1000;
readtimeout  = 1000;
extrainput   = Ignore;

# this protocol is just for testing
raw  { out "#\$1" "000"; in "%s"; }

vmeas   { out "#\$1" "07?";     in ">\$1" "07%d";  }
imeas   { out "#\$1" "08?";     in ">\$1" "08%f";  }
pmeas   { out "#\$1" "02?";     in ">\$1" "02%f";  }
rsetpt1 { out "#\$1" "71?";     in ">\$1" "71%f";  }
wsetpt1 { out "#\$1" "71%0.1E"; in ">\$1" "71";    }
rsetpt2 { out "#\$1" "72?";     in ">\$1" "72%f";  }
wsetpt2 { out "#\$1" "72%0.1E"; in ">\$1" "72";    }
whvpwr  { out "#\$1" "30%1b";   in ">\$1" "00";    }
rhvpwr  { out "#\$1" "30?";     in ">\$1" "30%1b"; }
dtype   { out "#\$1" "11?";     in ">\$1" "11%s";  }

I saw that you made some useful changes. I will try these out on occasion.
Heinz
