Channel. PID.TMin 0.0
Each of the eight PID memory locations can be assigned a temperature range for zoned
feedback. If zoned feedback is enabled by setting
Channel .PID.Zone
to
Auto
, any given
memory location is automatically recalled whenever the PID input temperature enters its
temperature range.
The
Channel .PID.TMin
instruction determines that temperature range. It assigns a lower
temperature bound to whichever memory location is currently selected. There is no TMax
instruction; the upper end of the temperature range is the next-highest TMin value in the memory
table.
Errors: Attempting to set the minimum zone temperature when no PID input channel is
selected produces a run-
Channel. PID.Zone { 1, 2, 3, 4, 5, 6, 7, 8, Auto }
Sets the PID temperature zone. A set of PID gains, an input sensor, and a minimum
temperature can be assigned to each of eight temperature zones. If the zone is set to
Auto
, a set of
stored feedback parameters is automatically recalled whenever the ramp temperature
(
Channel .PID.RampT
, which is usually the same as the feedback setpoint) enters one of the
temperature zones. Any changes to P, I, D, or the input sensor are automatically reflected in the
zone definition for the current zone.
All eight PID zones can be viewed as a table on the front panel; see the description of the Zone
button on page 66.
parameters and load them into the table. However, if the feedback parameters are already known,
they can be loaded into the table with a macro such as the following:
Out1.PID.Zone 1 ' select the first line of the table
' and disable zoned feedback
Out1.PID.Tmin 25 ' fill in the firs
t line of the table…
Out1.PID.P 1.5
Out1.PID.I 0.13
Out1.PID.D 0.04
Out1.PID.Input In1
Out1.PID.Zone 2 ' select the second line of the table
Out1.PID.Tmin 35
Out1.PID.P 0.75
Out1.PID.I 0.05
Out1.PID.D 0.03
Out1.PID.Input In3
Out1.PID.Zone 3 ' select the third line of the table
Out1.PID.Tmin 1000 ' ensure that this line is never used
Out1.PID.Zone Auto ' enable zoned feedback
Errors: Attempting to change the zone when no PID input channel is selected produces a run-
error.
