Delta RMC151 - Manual (Page 143)

3 Controller Features
• (1) Processing
Once the command has been received, the Status will
immediately be set to Processing. While in this state
the command is currently using the Curve Data
structure, and the curve is not ready for interpolation.
• (2) Part Complete
For all but the last part in a partial curve download,
once the command has completed processing the part,
this status value will be used. The user can now write
down the next part of the curve.
• (3) Curve Ready
Once the curve data has been processed, and the
entire curve is ready for interpolation, the status will
be set to this value. Notice that this value will be used
for only the final part for curves submitted in parts.
Therefore, for the last part of a curve, the Part
Complete (2) state won't be used—the status will
change directly from Processing (1) to Curve
Ready (3).
• (10+) Error
Values of 10 and above will indicate various errors.
When an error code is set in this register, it indicates
that the command is done trying to process this Curve
Data, but the curve was not submitted to the curve
store. See Curve Status Error Codes for a list of
possible error values.
It is good practice to set this value to zero when writing
the data.
1 Format One of the following:
20 - Evenly-Spaced Points
21 - Variable-Spaced Points
22 - Advanced Points
This value must be the same for each part.
2 PartOffset Offset of this part of the whole curve (in registers). This
value will change for each part.
3 PartLength Number of curve data registers in this part, not including
the 5 header registers with offsets 0-4. Typically, this value
is the same for each part except the last.
4 TotalLength Total length of curve data (sum of all parts). This is the
length of the corresponding single curve format, but with
the Status and Format registers stripped off. This value
must be the same for each part.
5..5+(L-
1)
PartData Segment of the curve data in the respective single curve
format. The curve data here consists of the corresponding
single curve format, but with the Status and Format
registers stripped off.
Downloading Partial Curves to the RMC
To download a large curve to the RMC, repeat the following procedure until all the data
has been downloaded:
• Write the data part to the RMC.
