Identifies the block execution methods available
for this resource, may be scheduled, completion

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 digital valve controller this value
is fixed at 3200 (100 milliseconds).
Memory Size
MEMORY_SIZE
22 RO NA 45 45
Date Type: Unsigned16
Memory, in kilobytes, available for additional
function blocks. Because no additional function
blocks may be added to DVC6200f instruments,
this parameter value is fixed at 45.
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 DVC6200f
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 DVC6200f 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 DVC6200f
instruments, this parameter value is fixed at 0.
RCAS Timeout
SHED_RCAS
26 RW ALL Positive 640000
Date Type: Unsigned32
Time duration (in 1/32 millisecond) at which to
give up on computer writes to function block
RCAS parameters. If this time is exceeded then
the function block will change to a mode other
than RCAS based on the SHED_OPT parameter
setting. Shed from RCAS mode never happens
when SHED_RCAS is set to zero.
