For example, a typical point is displayed below.
DEMO:B5.PNT, 0.1,,,
The following table provides possible combinations for the Foxboro Evo points in scpeng.sce file with DEMO SaveAll.
|
Symbol, Tolerance, Auto/ Manual, Local/Remote |
Description |
Represents |
|---|---|---|
|
Demo:B5.MEAS,0.0 |
Point with Tolerance 0.01 (default Tolerance), no Auto/Manual, no Local/Remote |
Valid point, recorded both in Auto & Manual, recorded both in Local & Remote |
|
Demo:B5.MEAS,, |
Point with Tolerance 0.01 (default Tolerance), no Auto/Manual or Local/Remote |
Valid point, recorded both in Auto & Manual, recorded both in Local & Remote |
|
Demo:B5.MEAS, |
Point with Tolerance (default Tolerance) |
Valid point, recorded both in Auto & Manual, recorded both in Local & Remote |
|
Demo:B5.MEAS |
No Tolerance specified |
Invalid point, is ignored from scenario recording |
|
Demo:B5.MEAS, 0.1 |
No Auto/Manual , no Local/Remote |
Valid point, recorded both in Auto & Manual, recorded both in Local & Remote |
|
Demo:B5.MEAS, 0.5,, |
No Auto/Manual , no Local/Remote |
Valid point, recorded both in Auto & Manual, recorded both in Local & Remote |
Notes:
If the watch point file, scpeng.sce, is modified, restart the Dynsim simulation to re-read the file.
SCP engine logging action does not start recording a Scenario if the watch point file, scpeng.sce, is empty.
If the watch point file contains a point (like MEAS, SPT, OUT) in a block that has auto/manual and local/remote flags (like AOUT or PIDX), MA & LR will be automatically added to the list of watched points by the SCPEngine.
If a Scenario is manually created, then add a WAIT statement of at least 0.5 seconds after an MA or LR point is set in the Scenario.
There may be a time delay on starting, recording or playback for the first time after loading a simulation with large a watch point file.
When saving Snapshots, add RUN and WAIT commands after the SAVE command. The WAIT statement value should be sufficient for the Snapshot to save. This may require a few minutes.
Known problem - the tolerance check for reals is poorly constructed.
Known problem - the user may specify FIELD3 and FIELD4 but these fields will be ignored as these checks have not yet implemented.
