6-7 Temperature Controller Commands
6-7-1 TCAutoTune
Syntax
returnstate = TCAutoTune(TController,mode)
Remarks
Typical Example
Argument Type Description
returnstate bool 1 if the function is successful otherwise 0.
plcname string Name of PLC to upload the program from.
filename string Name of the file on disk to upload the program
to. If a drive and path are not specified, the file
is created in the current directory, which may
not be the same as the application directory. If
a filename is specified as "" the user is
prompted at runtime for a filename.
processed bool processed is set to 'TRUE' when the operation
is actually completed.
Note: The operation may not be complete immediately after the statement has been
executed. The processed flag 'done' is set at a later time when the operation
has been completed. Therefore, if using statements that require the upload to
be completed create an On Condition script containing the code to be
executed after the upload, with the processed flag as the expression (e.g.
'done').
Note: This command can only be used when the PLC is in 'STOP' mode. Refer to
chapter 6, GetPLCMode or chapter 6, SetPLCMode for further information.
Argument Type Description
returnstate bool 1 if the function is successful otherwise 0.
TController string This is a string representing the name of the
temperature controller.
mode point This is a point depicting the mode of operation
and defines the operation to be carried out
when a TCAutoTune command is issued.
0: Indicates that the auto-tuning operation is to
be stopped.
1: This mode is supported on the E5*K and is
used to set the limit cycle of the manipulated
variable change width to 40%.
