• Where to Find
Description
MaxBuffDepth Numeric
•
Status table field: ≈36
Maximum number of buffers the CR800 will use to process lagged measurements.
MaxPacketSize Numeric
• Settings Editor:
Advanced | Max Packet Size
Maximum number of bytes per data collection packet. Default = 1000.
MaxProcTime
Numeric
• Status table field: ≈33
Maximum time (μs) required to run through processing for the current scan. Value is reset
when the scan exits. Enter 0 to reset. Updated at the conclusion of scan processing, prior to
waiting for the next scan.
MaxSlowProc
Time()
Numeric
•
Status table field: ≈41
Maximum time (μs) required to process a SlowSequence scan in the CRBasic program.
Defaults to 0 until a scan runs. Enter 0 to reset.
MaxSystem
ProcTime
Numeric Y
•
Status
table field: ≈40
Maximum time (μs) required to process the auto (background) calibration, which runs in a
hidden slow-sequence type scan. Displays 0 until an auto self-calibration runs. Enter 0 to
reset.
MeasureOps Numeric Y
•
Status table field: ≈30
Reports the number of task-sequencer opcodes required to do all measurements. Calculated
at compile time. Includes opcodes for calibration (compile time), auto (background)
calibration (system), and slow sequences. Assumes all measurement instructions run each
scan. Updated after compile and before running.
MeasureTime Numeric Y
•
Status table field: ≈31
Reports the time (μs) needed to make measurements in the current scan. Calculated at
compile time. Includes integration and settling time. In pipeline mode, processing occurs
concurrent with this time so the sum of MeasureTime and ProcessTime is not equal to the
required scan time. Assumes all measurement instructions will run each scan. Updated
when a main scan begins.
MemoryFree Numeric Y
• Station Status field: Memory Free
• Status table field: ≈27
Unallocated SRAM memory on the CPU (bytes). All free memory may not be available for
data tables. As memory is allocated and freed, holes of unallocated memory, which are
unusable for final-storage memory, may be created. Updated after compile completes.
