RAMP SOAK BLOCK
3-12
08 Restart Segment (RESSEG) ............................................................................................. CWR
Restart Segment determines the segment to use on a cold instrument restart. On a warm
instrument restart, the block will resume at the segment that was active before the restart.
PRESET 0 Indicates an inactive profile.
PRESET 1 - 36 Restarts at the beginning of the specified segment number.
PREVIOUS 255 Resumes at the segment that was active before the restart. Default
value is PREVIOUS.
09 Number of Segments (NUMSEG)....................................................................................... C-R
Number of configured segments in the profile. Value 1 through 36 is allowed. Default is 1.
10 Command (CMD) .................................................................................................................-WR
This provides a dummy location in the database to which commands can be addressed using
a long state variable. The value read from this location will always be 0. The following values,
when written to this location, will be interpreted as commands:
RESET 1 Resets the profile to segment 1 and the mode to run.
STOP 2 Resets the profile to segment 1 and the mode to hold.
HOLD 3 Stop and hold profile
RUN 4 Continue profile.
SKIP 5 If the profile is not on the last segment it will go to the next segment.
Else if REPEAT is NO then the profile is complete. Else it will put the
profile at the start of the first segment.
The ramp/soak RESET and STOP commands received through the message handler will
reset the ramp/soak when it is received, regardless of the loop or block state.
11 Soak Hysteresis (SHYST) ................................................................................................. CWR
Value of hysteresis for guaranteed soak segments. Valid floating-point values are 0.0 or
greater. Default is 0.0
12 Ramp Hysteresis (RHYST) ............................................................................................... CWR
Value of hysteresis for guaranteed ramp segments. Valid floating-point values are 0.0 or
greater. Default is 0.0
13 Start Value (START) .......................................................................................................... CWR
This is the value that the profile starts at if the startup type is START. It is always used to
calculate the ramp rate of the first segment if the first segment is a ramp segment. Default is
0.0
14 Result (R) ........................................................................................................................... CWR
The output of the profile. The ramp function changes the block result (setpoint) up or down at
a linear rate over the specified period of time. The soak function maintains the block result at a
fixed value for the specified period of time. A step function has a specified time of zero.
