*** 78 SET HIGH OR LOW RESOLUTION ***
DATA STORAGE FORMAT
FUNCTION
This instruction enables high resolution (5
character) or low resolution (4 character) final
data storage format. Instruction 78 should be
entered ahead of the output instructions for
which the specified resolution is desired. The
default format is low resolution. At the
beginning of each program table execution, the
low resolution format is automatically enabled.
PARAM. DATA
NUMBER TYPE DESCRIPTION
01: 2 0 = low resolution;
1 = high resolution
Outputs Generated: 0
*** 79 SAMPLE ON MAXIMUM OR ***
MINIMUM
FUNCTION
Instruction 79 samples specified input location
values at the time a new maximum or minimum
value is detected by a previous Maximize (73)
or Minimize (74) Instruction. When the Output
Flag is set, the values copied to Intermediate
Storage are transferred to Final Storage.
Instruction 79 must directly follow the maximum
or minimum Instruction to which it refers. If the
previous Instruction 73 or 74 has more than 1
repetition, Instruction 79 samples whenever a
new maximum or minimum is detected in any of
the locations. If sampling is to occur only when
a specific input location shows a new maximum
or minimum, the previous Maximize or Minimize
Instruction should have one rep referring to that
input location.
PARAM. DATA
NUMBER TYPE DESCRIPTION
01: 2 Repetitions (number of
sequential locations to
sample)
02: 4 Starting input location no.
Outputs Generated: 1 per repetition
*** 80 SET ACTIVE STORAGE AREA ***
FUNCTION
Instruction 80 is used to redirect Output data to
either of the Final Storage areas or to Input
Storage and to set the array ID for Final Storage.
The area set by Instruction 80 remains active
until changed by another Instruction 80 or the
table ends. At the beginning of each table the
Active Output area is set to Final Storage Area 1.
When directed to Final Storage, the second
parameter can be used to set the output array
ID. Instruction 80 should follow the instruction
setting flag 0. If parameter 2 is 0, the array ID is
determined by the instruction location number of
Instruction 80 or by the instruction that set the
Output Flag, whichever comes last. When data
are sent to Input Storage, no array ID is sent.
Output array ID’s can be indexed within a loop.
PARAM. DATA
NUMBER TYPE DESCRIPTION
01: 2 Storage area option
00 or 01 = Final
Storage Area 1
02 = Final Storage Area 2
03 = Input Storage Area
02: 4 Starting input location
destination if option 03
Output Array ID if options
0-2 (1-511 are valid IDs)
*** 82 STANDARD DEVIATION IN TIME ***
FUNCTION
Calculate the standard deviation (STD DEV) of
a given input location. The standard deviation
is calculated using the formula:
S = ((
Σ
X
i
2
- (
Σ
X
i
)
2
/N)/N)1/2
where X
i
is the ith measurement and N is the
number of samples.
