Introduction to Ramp / Soak Profile Control
30 programs (1 if functionality =
Standard
)
140 programmable segments (10 if functionality =
Standard
)
5 segment types –
Soak, Ramp Rate, Ramp time, Wait*, Step, End
Programmable time units – hours or minutes
Programmable Ramps – can be programmed as rates or time units
Program Repeat – 0 to 10 times or continuously
Program holdback hysteresis
Separate settings for ramp and soak segments. Can be applied above, below or above and
below the setpoint.
8 Segment Events* – enabled / disabled per segment
PV Event* – Event may be generated if PV is above/below configured trip value or deviates
from configured trip value
Timed Event* – Event may be generated during a segment for a defined time period
User Value* – configure an analog value that is output for the duration of each segment
Programmable start conditions – Program, Local Setpoint, Current PV
Retort function* – ensures safe operation under fault conditions, see Section 7.6.4, page 64.
Recovery action – determines profile operation under power fail / PV fail conditions
Fast Run mode – runs program 8 times normal speed for test/commissioning
*Enabled only if functionality =
Extended
/
Dual
.
The
Ramp
/
Soak
Profile
facility is a setpoint profile generator which can be
used with any type of control process for more complex setpoint control. A
Profile
program is made up of
Ramps
(the setpoint is increased / decreased
at a linear rate until it reaches the desired value) and
Soaks
(the setpoint is
maintained at fixed value for a set time duration).
Note
. Profile functionality is not enabled if functionality level =
Basic
, or Dual
loop application templates are enabled.
