<H1>FOCUS SPS Commands</H1>
|
|
<P>
|
|
The following commands are handled with the help of the Siemens SPS-system.
|
|
</P>
|
|
<h2><a name="SHUDDER">The Shutter</a></h2>
|
|
<p>
|
|
Even the shutter can be controlled from within SICS. This is safe because
|
|
the shutter will not open if the door to the instrument is open. In Local
|
|
Beam Control (LBC) speak this status is named "Enclosure is broken". Be
|
|
careful anyway because some idiots may climb the fence..... The following
|
|
SICS commands control the shutter:
|
|
<dl>
|
|
<DT>shutter
|
|
<DD>The command shutter without arguments returns the status of the shutter.
|
|
This can be one of open, closed, Enclosure is broken.
|
|
<DT>shutter open
|
|
<DD>opens the shutter when possible.
|
|
<DT>shutter close
|
|
<DD>closes the shutter.
|
|
</dl>
|
|
</p>
|
|
<h2><a name="COLLI">The Collimator</a></h2>
|
|
<p>
|
|
FOCUS is equiped with a rotating collimator. This can be either idle or
|
|
moving. This collimator can be controlled from SICS with the following
|
|
commands:
|
|
<dl>
|
|
<dt>colli
|
|
<dd>prints the current status of the collimator which can be either
|
|
idle or moving.
|
|
<dt>colli idle
|
|
<dd>switches the collimator to idle mode.
|
|
<dt>colli moving
|
|
<dd>swicthes the collimator into moving mode.
|
|
</dl>
|
|
</p>
|
|
<h2><a name="FBOX">Flight Box</a></h2>
|
|
<p>
|
|
The flight path in the detector box is normally filled with argon.
|
|
In order to detect a possible
|
|
leak an oxygen sensor is provided. The status of this sensor can be inquired
|
|
from within SICS with the command:
|
|
<dl>
|
|
<dt>fbox
|
|
<dd>prints the status of the flightbox. Which can be either OK or Problem.
|
|
</dl>
|
|
Obviously this cannot be controlled from the computer as any problem with
|
|
this requires massive mechanical intervention (searching the leak and
|
|
refilling argon).
