I. Purpose
Members of the C465 family are programmable ramp controllers
capable of generating an analog waveform which is based on:
Time into cycle
Current (MDAT value)
Change in current (MDAT value)
The time portion of the waveform is updated at up to a 10
KHz rate, and the MDAT portion is updated at a 720 Hz rate.
The C465 also contains digital control capabilities to turn
on (relay and TTL), turn off (relay and TTL), change the
polarity, and reset (relay and TTL) a power supply. It can
also return sixteen status bits from the power supply.
The C465 family is presently comprised of four modules,
C465, C466, C467, and C468. The C465 and C467 modules are
bipolar while the C466 and C468 modules are unipolar. The
C467 and C468 modules provide both analog and digital
references and can pass 32 bits of external status while the
C465 and C466 modules provide only an analog reference and
access to 16 bits of external status.
Note: The current firmware version number for 465 and 467
modules at the time of this writing is 1.6. The
version number for 466 and 468 modules is 1.6.
Version 1.61, which is a bug fix, exists in code,
but is not in the field.
II. Device Descriptions
The ACNET device descriptions for this module are contained
in a separate document.
III. Features
A) Output Function
The output waveform has the form:
output = sf1*m1*f(t) + sf2*m2*g(M1) + sf3*m3*h(M2)
where:
sf1, sf2, sf3 are constant scale factors having a range of
-128.0 to +127.9 for the C465 and C467 and 0 to +255.9 for
the C466 and C468
m1, m2, m3 are raw MDAT readings divided by 256
f(t) is an interpolated function of time which is initiated
by the 'or' of up to 8 TCLK events
g(M1) and h(M2) are interpolated functions of selected MDAT
parameters
B) MDAT
MDAT parameters are decoded and stored in hardware
registers where software can then access the data. All
currently defined MDAT parameters plus new parameters up to
a total of 64 are supported.
Parameters represented by bipolar, signed, 2's
complement numbers (typecodes 1-7,11-17,21-27,31-37,41-47,
61-67) are used directly in calculations and range in value
from -32768 to 32767. Parameters represented in unipolar,
unsigned form (typecodes 00,10,20,30,40,50-57,60,70-77) are
shifted down by one bit (divided by two) before they are
used in calculations, and they range from 0 to 32767 in
value. (Note : Negative MDAT multiplier values are set to
zero for the C466 and C468 modules.)
C) Scale Factors
Scale factors are 16 bits long. The upper byte is
interpreted as the whole number part and the lower byte is
interpreted as the fractional part of the scale factor.
Positive and negative scale factors are allowed for the C465
and C467. The largest negative scale factor is -128.000,
and the largest positive scale factor is approximately
127.996. For the C466 and C468, the scale factors range
from 0.0 to approximately 255.996.
Sixteen scale factors are presently supported with an
additional special 'null' scale factor. Any scale factor
can be applied to any of the terms, and any scale factor can
be used any number of times.
Changes to active scale factors are updated at the
start of the next ramp.
Scale factor pointer changes are also updated at the
start of the next ramp.
D) Overflow Errors
The firmware checks for overflow errors following each
calculation and maintains the previously calculated value if
one is detected. An overflow error counter is also
incremented.
E) Ramp Output
The outputs are provided in analog format.
(16 bits, +/- 10.0V) (C465 and C467)
(16 bits, 0 - 10.0V) (C466 and C468)
F) Tables
Each term in the output function will have fifteen
possible tables with a maximum of 64 entries each.
Additionally, there is a table for each term which is
defined as a zero or null function.
Table selection is effected by an interrupt. Thirty
two interrupt levels are available, each is asserted by the
'or' of up to 8 programmed TCLK events. No one given TCLK
event can trigger multiple interrupt levels at the same
time. Interrupt levels can also be asserted via an
F(17)A(10) CAMAC command. The complete list of TCLK events
can be found in the TCLK Event Definitions document.
Upon assertion of an interrupt, the module will begin
using three user specified tables (one for each term in the
output function). The null function should be specified for
unwanted terms.
The g(i) and h(i) values are all directly individually
accessible. For the f(t) table the value entries are also
directly accessible, but the delta t values must be accessed
by first accessing its accompanying value entry.
It is important to note that the maximum valid delta t
value in a time table is 32767 clock ticks. This means that
the high order bit for delta t values is not used. If it is
set in a C465 or C467 module, the card will automatically
clear it. If it is set in a C466 or C468 module, the
corresponding f(t) value is treated as a negative number.
Tables are selected via pointers with values of 1 to 15
indicating ramp numbers 1 through 15. A value of zero
indicates the 'null' ramp.
Any changes to an active table are implemented
immediately. However, changes to table pointers are updated
at the start of the next ramp.
G) MDAT Multipliers
MDAT multipliers presently consist of the raw 16 bit
MDAT readings taken from the link divided by 256. They are
updated at a 720 Hz rate. They are accessed via pointers
with a value of 8 indicating MDAT code 10 and a value of 48
indicating MDAT code 60. The range of valid pointer values
is from 1 to 64. A pointer value of zero indicates that no
MDAT multiplier is desired, and a constant multiplier of 1
is inserted. The MDAT pointers are updated at the start of
a ramp.
H) STOP/CONTINUE Mode
This module can be configured in such a way that the
STOP ($62) and CONTINUE ($63) TCLK events can be used to
freeze and unfreeze the output waveform. When in this mode
the thirty first interrupt level is redefined to function as
a 'stop' interrupt, and the thirty second interrupt level
becomes the 'continue' interrupt. When this mode is
selected an event $62 is loaded into the clock event array
for the thirty first level, and an event $63 is loaded in
for the thirty second level. These events can be
subsequently replaced by any other TCLK events if so
desired. The 'stop' and 'continue' interrupts can also be
performed via CAMAC.
I) Power Supply Turn Off Mode
The C465 can be placed in a mode which will cause it to
send an off command to its associated power supply as a
result of a clock event. If this mode is selected, event
$4E is loaded into the thirtieth clock interrupt level.
This event can be replaced by any other TCLK events if so
desired. Any clock event which triggers the thirtieth
interrupt level will then result in a power supply off
command being sent.
J) Copy Time Table to G(I) Table Mode
There are situations under which one might want to
switch modes from time dependency to MDAT. This can be
automatically done by the C465 by setting it up for copy
time to G(I) mode. Under this mode, any TCLK event which
triggers interrupt level twenty nine will cause the time
component of the present waveform to be copied into the
presently playing G(I) value table at the slots surrounding
the most recently decoded MDAT value. This copying will not
take place if the time table is still playing or there is no
active G(I) table. In any case, the original time table
will remain unaffected. The G(I) table, however, has been
permanently changed. The original G(I) values can be
restored via an F(26)A(10) CAMAC command. This mechanism
stores only the first change made to any G(I) table since
the most recent restore.
K) Copy Time Table to H(I) Table Mode (*)
This mode works in exactly the same way as the copy
time to G(I) table described above. The only difference is
that this mode operates on interrupt level twenty six and
that the original H(I) table values can be restored by an
F(26)A(11) CAMAC command.
L) Ramp Down Mode
When a C465 module is following an MDAT table it
produces a specific output for a specific MDAT value.
Therefore, if the MDAT signal happens to be the energy of a
given accelerator, the module will produce the same output
for the upward portion of a ramp as on the downward portion
except that it is reversed in time. Since there are usually
no particles in the accelerator during the downward portion
of the ramp, this behavior is not always useful and is
sometimes harmful to power supplies. The ramp down mode,
when selected, reassigns interrupt level twenty eight to
trigger it. If one of the events for interrupt level twenty
eight is then detected, the C465 will calculate new MDAT and
MDAT value tables to bring the output of the card back to
the value of slot zero in the presently playing MDAT tables.
The newly calculated tables will overwrite G(I) and H(I)
tables number fifteen. Do not use these tables for normal
output functions when this mode is in effect. This mode
will not take effect if the MDAT tables are already at slot
zero or if G(I) and H(I) null tables are presently playing.
In these cases, the command is ignored.
M) Archive data mode
When this mode is activated interrupt level twenty
seven is reassigned to trigger it. If one of the eight
events for that level is subsequently detected, the module
will automatically store away pertinent information
concerning its present output and the values used in
calculating that output. This buffer of data can then be
read out via an F(3)A(3) CAMAC command. A complete listing
of the archival data structure can be found in section VI.
N) Copy table mode (*)
When this mode is activated, interrupt level twenty
five is activated to trigger it. If one of the eight
events for that level is subsequently detected, the module
automatically copy the entire F(T), G(I), and H(I) tables
which were selected by earlier F(20)A(4) CAMAC commands.
Choosing a table number of zero disables copying for the
corresponding table type. Copies can be set up to occur
only once or until a change in the copy table setup is made.
Table copies can also be manually triggered via an
F(25)A(4) command.
O) Add table mode (*)
When this mode is activated, interrupt level twenty
four is activated to trigger it. If one of the eight
events for that level is subsequently detected, the module
automatically adds the entire F(T), G(I), and H(I) tables
which were selected by earlier F(21)A(4) CAMAC commands.
Choosing a table number of zero disables adding for the
corresponding table type. Adds can be set up to occur
only once or until a change in the add table setup is made.
Table adds can also be manually triggered via an
F(25)A(5) command. Note that the tables which are being
added from are not modified.
P) Special LAM Status
Bit #8 of the LAM status is set whenever the end of an
MDAT I table is reached without finding an appropriate I
value. The previous MDAT component to the waveform is
maintained in this event. Bit #14 indicates that an
overflow error has occurred during a calculation. The LAM
register also contains two bits (0 and 2) which indicate
ramp enable/disable status. They always contain values
opposite to one another in order to facilitate digital
alarms for either an enabled or disabled state. Bit #15
being set indicates that a CAMAC command has been received
by the module containing erroneous data. The CAMAC command
is discarded in this event. Bits 12 and 13 indicate the
absence of TCLK and MDAT signals respectively. Finally, bit
10 indicates the absence of an external permit signal, and
bit 11 indicates a power supply status error. On C467 and
C468 modules bit 9 being set indicates a 'B' board power
supply status error.
Q) Initialized State
When the module is powered up or reset all scale factor
pointers will be set to the null scale factor and all scale
factor values will be set to 0.0. Also, all table pointers
will be set to the null table and all table values will be
set to zero. The clock event table will be filled with NOOP
(FE) clock events, and all special operating modes will be
deselected.
R) DAC Update Frequency
This module operates at a DAC update frequency of
10 KHz when it is powered up. In some applications this
frequency may not be necessary or it may even be undesirable.
Therefore, the capability exists to change the update
frequency via a CAMAC command. The allowable frequencies
are 1, 5, and 10 KHz. Changing the update frequency also
inherently changes the time scaling of the f(t) table but
has no effect on the MDAT tables.
S) Clock Interrupt Disable
The module can be made to ignore clock event interrupts
by sending it an F(24)A(5) command. Clock interrupts can be
reenabled with an F(26)A(5) command or by resetting the
module.
