Cycle Type
CYCLE_TYPE

Data Type: Bit String
0 = Inactive

completion of block execution
Cycle Selection
CYCLE_SEL
20 ALL 0: Scheduled 0: 0
Data Type: Bit String
0 = Inactive
1 = Active
Identifies the block execution method selected
for this resource.
Minimum Cycle Time
MIN_CYCLE_T
21 RO NA 3200 3200
Data Type: Unsigned32
Time duration of the shortest cycle interval (in
1/32 millisecond) of which the resource is
capable. In the DVC this value is fixed at 3200
(100 milliseconds).
Memory Size
MEMORY_SIZE
22 RO NA 0 0
Date Type: Unsigned16
Memory, in kilobytes, available for additional
function blocks. Because no additional function
blocks may be added to DVC6000f Series
instruments, this parameter value is fixed at 0.
Nonvolatile Cycle Time
NV_CYCLE_T
23 RO NA Positive 576,000
Date Type: Unsigned32
This parameter identifies the minimum time
interval (in 1/32 milliseconds) between copies
of NV class data to NV memory. NV memory is
updated only if there has been a change in the
dynamic value. The last value saved in NV
memory will be available for the restart
procedure or a power cycle. A non-zero value
regulates the frequency of writes, thus
protecting the life span of the device. If the
value is zero, data will never be automatically
copied. Changes made by other than
publishing to NV parameters will be copied to
non-volatile memory immediately. For
DVC6000f Series instruments, this parameter
value is fixed at 576,000 (18 seconds).
Free Space
FREE_SPACE
24 RO NA 0 to 100% 0
Data Type: Float
Percent of memory available for additional
function blocks (see also MEMORY_SIZE).
Because no additional function blocks may be
added to DVC6000f Series instruments, this
parameter value is fixed at 0.
Free Time
FREE_TIME
25 RO NA 0 to 100% 0
Data Type: Float
Percent of block processing time that is free to
process additional blocks. Because no
additional function blocks may be added to
DVC6000f Series instruments, this parameter
value is fixed at 0.
