MBSdaTask - NEC Sequenced D/A converter service
MBSdaTask <argument
list>
I/O service for NEC Sequenced D/A converter CAMAC modules
and NEC Sequenced D/A converter kbuss modules.
These modules are part of
the Magnet Bias Sequencer system and are used to provide signals for driving
power supplies in an AMS system.
Argument processing is done using
Unix long argument syntax.
The values of all of the parameters listed here
(whether or not they were supplied on the command line) are printed on
stderr when the program starts.
- --dbman_host <hn>
The host where dbman is running.
If this argument is not supplied the default
is localhost.
- --dev_camac <path>
The pathname to the device to open when --drv specifies a CAMAC device.
The
default is: /dev/camac
- --dev_kbuss <path>
The pathname to the device to open when --drv specifies a KBUSS device.
The
default is: /dev/kbuss
- --drv <name>
The driver key. - --cmin
The minimum crate number in CAMAC.
The minimum board number in KBUSS.
If this is not supplied it defaults
to 0.
- --cmax
The maximum crate number in CAMAC.
The maximum board number in KBUSS.
If this is not supplied it defaults
to 99.
- --show_tbl
If this is supplied then the DATA table is printed to stderr. - --help
Print the internal help information and exit.
These
keys are used with CAMAC:
CAMAC
CAMAC_2
CAMAC_3
CAMAC_4
CAMAC_5
In this case the program opens /dev/camac by default.
These keys
are used with KBUSS:
KBUSS_1
KBUSS_2
KBUSS_3
KBUSS_4
KBUSS_5
KBUSS_6
In this case the program opens /dev/kbuss by default.
When using CAMAC C is the crate number, and N is the
slot number.
When using KBUSS C is the board number, and N is not used and
may be set to any value to facilitate sorting the database reports if desired.
- DevNECda
- There should be 7 DATA records of this type created for each D/A
module in the system.
The ChNo fields should be 0 - 7. Each ChNo has a specific
use. See "ChNo usage" below.
- ChNo=0
The control register.
Bit 0 is the norm/maint mode selection bit.
Bits
2-1 are used the select which value register is applied to the D/A output
when in maint mode.
- ChNo=1
D/A value register 0. - ChNo=2
D/A value register 1 - ChNo=3
D/A value register 2 - ChNo=4
D/A value register 3 - ChNo=5
State selection register 0. - ChNo=6
State selection register 1.
There is nothing to poll.
#
# this example services crates 1 thru 4
# dbman is running on the same host
#
MBSdaTask --dbman_host localhost --drv CAMAC --cmin 1 --cmax 4
#
#
#
# this example services KBUSS modules
# dbman is running on the same host
# (the min and max board numbers aren’t specified)
#
MBSdaTask --dbman_host localhost --drv KBUSS_1
When using KBUSS the S2
line must be enabled when the driver is installed or by using the kbuss_ctl(8)
utility program.
Yes, we need more info in this manual page..
