The Supervisory parameters are available in PAGE-12 and provides communication parameters to the user and also can be
used to exercise control over operator level or to use the controller's in-built ability to improve upon the control performance
under conditions that are beyond the self-detection capabilities of the controller.
The parameters are listed in Table 6.1 below followed by their definitions.
SUPERVISORY PARAMETERS
Table 6.1
Settings
(Default Value)
Parameter Description
This parameter defines the communication speed expressed in
“Bits per Second”. This parameter is settable as 1200, 2400, 4800
or 9600 and must be set in accordance with the communication
speed set for the Master Device.
BAUD RATE
4800
9600
1200
2400
(Default : 4800 )
CONTROLLER ID NUMBER
This parameter, settable from 1 to 8, assigns a unique slave
identity number to the controller that the Master Device uses to
address the controller for data read/write operation.
1 to 8
(Default : 1)
SETPOINT LOCKING
Set to Yes to Lock the SP editing on the Lower Readout.
No
Yes
(Default : No)
SELF-TUNE ON SETPOINT CHANGE
The controller's “X-THERM” algorithm is powered with the ability
to self-detect the need for Tuning / Optimization of the controller if
there is a substantial change in the SP by the user. The algorithm
takes into account the magnitude of SP change and the
Temperature Range. If this parameter is set to ‘Enable’, the
controller, if required, automatically optimizes the control
parameter values while approaching the new SP. The user can set
this parameter to ‘Disable’ if this feature is not desired.
No
Yes
(Default : No)
User Manual

Disable
(Default : Disable)
OPTIMIZE COMMAND
(Available for PID control only)
Set to ‘Yes’ to initiate a new tuning cycle or set to ‘No’ to abort a
tuning operation in progress.
