instructions.
Channel. Tune.Lag 0.0
Channel. Tune.StepY 0.0
These parameters provide the PID autotuners with initial guesses of the system response
magnitude and time.
Channel .Tune.StepY
controls the height of the step response or relay
disturbance, while
Channel .Tune.Lag
determines how long the tuner waits before it first
evaluates the effect of the disturbance. If either value is too small, the autotuning algorithm will be
susceptible to noise. The Y step size should be high enough to produce a temperature rise of
several degrees, and the lag should be long enough for the temperature to rise noticeably.
Errors: Attempting to set step Y or Lag when no PID input channel is selected results in a run-
Channel. Tune.Mode { Off, Auto, Step, Relay }
Starts or stops PID autotuning.
Step
starts the step response tuning algorithm;
Relay
starts the
relay tuning algorithm. In
Auto
mode, the CTC100 begins a step response if the PID output is less
than half of Channel .Tune.StepY ; otherwise it begins the relay tuning procedure. Off cancels
Channel. Tune.Type { Cons, Moderate, Aggr, Auto }
Determines how the PID tuner sets the feedback gains.
Cons
results in slow feedback response
rates with little overshoot of the setpoint.
Aggr
results in fast response, but much more
overshoot.
Moderate
produces intermediate results.
Auto
uses the conservative setting with the
step response tuner and the aggressive setting with the relay tuner.
Error codes
The C an error in a macro and
System.COM.Verbose
is
set to High . The error code appears in the error message sent to the communications port that
initiated the macro, and is accompanied by an explanation of the error and which instruction
caused the error. For example, if you send the word
Hello
to the CTC100 over the RS-232 port
when
System.COM.Verbose
is set to
High
, the CTC100 replies with the following message:
Error: "hello" is not a valid instruction (assembly error -113)
-100 - 199: assembly errors
Assembly errors are produced before the macro starts to run. If an assembly error is reported,
the macro was cancelled before it began running.
-102: Empty instruction. The instruction consisted of two quotes or parentheses in a row,
with no text in between.
-113: Invalid instruction. The instruction was not recognized.
-109: Multiple argument error. Two or more arguments were expected, and the arguments
provided did not conform to the types of arguments expected.
-121: Numeric argument error. A numeric value was expected, but a non-numeric argument,
or no argument, was provided.
-158: List argument error. The argument must be chosen from a list of possible values, but
the argument provided is not on the list.
