DSmngr - double slit manager
DSmngr <argument list>
This
program manages NEC double slits and other devices using a similiar control
scheme.
Arguments are processed using Unix long argument syntax.
- --mngr <fn>
The CONFLIST file from which to obtain the configuration information.
If
this is not specified it defaults to "MNGRconf" in the current working
directory (i.e. the directory where the program was started).
- --mngr_pn <fn>
The program name to use when parsing the CONFLIST file.
If this argument
is not specified it generally defaults to the program name.
- --show_tbl
If this argument is present the contents of the CONFLIST table is printed
to stderr - --diag
If this argument is present stdout and stdin are left open and the program
may be killed by SIGINT. - --verbose=<n>
Normally the program does it’s work silently. This sets the level of logging
information. The number is optional but if provided it must include the
"=". If no argument is provided the default level is 1.
0 - work silently
1 - print signon msg, option settings
The configuration file uses the
libmngr(3mngr)
facility to connect internal parameters to the AccelNET database. The mappings
for this program are given below.
Parameters needed by this program can
be combined with parameters belonging to other programs. The "program name"
field in the configuration file differentiates the entries.
DSmngr uses
"DSmngr" as the program name when searching the file.
One Group is assigned
for each device to be managed. The maximum number of groups which can be
managed is 15.
These parameters are the analog position
control for the slit controller. It should be owned by
DSmngr and the permissions
set for
indirect update.
When a new position command is issued DSmngr intercepts
the command checks the power status control (ctl5) and if the power is
on the new position is written to the database. Next the enable status
control (ctl1,2,3,4) is asserted momentarily to start the slit drive moving.
- comm1
-XDC - the displacement control for the -X axis - comm2
+XDC - the displacement control for the +X axis - comm3
-YDC - the displacement control for the -Y axis - comm4
+YDC - the displacement control for the +Y axis
These
parameters are the analog position read for the slit controller. When the
controller power is turned on (ctl5) this value is read and the corresponding
analog position control (comm1, comm2, comm3. comm4) is set to the same
value.
- read1
-XDR - the displacement read for the -X axis - read2
+XDR - the displacement read for the +X axis - read3
-YDR - the displacement read for the -Y axis - read4
+YDR - the displacement read for the +Y axis
These
parameters are used to start the slit drive moving. Usually it has control
type Mom and should be owned by (or at least writable by) DSmngr. When a
position update is received (comm1, comm2, comm3, comm4) the control is
asserted for one second. The rest value is
0.0 and the asserted value is
1.0.
- ctl1
-XenaSC - the enable status control for the -X axis - ctl2
+XenaSC - the enable status control for the +X axis - ctl3
-YenaSC - the enable status control for the -Y axis - ctl4
+YenaSC - the enable status control for the +Y axis
- ctl5
PwrSC - the power status control This control can be owned by DSmngr and
set for indirect update.
However, this isn’t necessary, it can be owned
by another task. If it is "indirect" the program will manage it as necessary.
If it is "direct" the program only read the value, it doesn’t require write
permission.
The expected values are 0.0 for off, and 1.0 for on.
If there
is no power status control for the device then this parameter should be
entered into the configuration file with Label and RefName set to NULL.
If this entry is missing DSmngr will complain about about not being able
to start a move because the power is off.
If the parameter is "indirect"
the program will emit a advice message saying that this isn’t necessary.
If it ever becomes a problem the expected values for the enable status
controls etc. will be changed so they come from the config file.
