FlexStat (General) 9 Application Guide, Rev L
Modifying the Standard Control Basic Programs
Programs 1 through 5
Control Basic programs 1 through 5 are used for built-in applications
and can NOT be modied directly. Programs 6 through 10 are empty and
can be used for additional programming. Using BACstage or TotalControl,
a program (1 through 5) can be copied, pasted into a new program code
object (6 through 10), edited, and run in place of the original. (Although
programs 1–5 cannot be edited, they can be halted and set to not autorun
aer restart.)
Because programs are executed sequentially, if a program is copied
and modied, ALL of the following programs must also be copied
(even if they are not modied)! For example, if program 2 is copied
into program 6 and modied, then programs 3 through 5 (even if
they contain no modications) must also be copied into programs 7
through 9. Then programs 2 through 5 are set to NOT autorun, pro-
grams 6 through 9 are set to autorun, and the FlexStat is restarted.
Program 1
Program 1 interacts with the user interface (display and menus). If
Program 1 is copied and replaced, ensure that the common code (up to
the application branch code section) in Program 1 is running. Failure
to do so may disable one or more user interface functions.
In all models, the common code ends at nearly the boom of the entire
code and is before the application lines (as relevant to the model):
AHU_CODE, FCU_2_PIPE_CODE, etc.
In rmware R1.3.0.8 and aer, the branch code section is somewhere
around line 518 in BAC-1xx63, line 522 in BAC-1xx36, or line 370 in
BAC-1xx30 and comes aer:
END_COMMON_CODE:
END
Searching for “COMMON” will quickly nd the line. Earlier rmware
versions do not have this convenient ag.
In BAC-1xx63, rmware R1.3.0.4 and earlier, the branch code section is
somewhere around line 457 and looks similar to:
REM PERFORM APPROPRIATE SECTION OF CODE BASED ON
FLEXSTAT CONFIGURATION
IF APP_MAIN_TYPE = AHU THEN
GOTO AHU_CODE
ELSE IF APP_MAIN_TYPE = RTU THEN
GOTO RTU_CODE
ELSE IF APP_MAIN_TYPE = FCU THEN
IF APP_SUB_TYPE = PIPE2 THEN GOTO FCU_2_PIPE_CODE
IF APP_SUB_TYPE = PIPE4 THEN GOTO FCU_4_PIPE_CODE
ELSE IF APP_MAIN_TYPE = HP THEN
GOTO HP_CODE
ENDIF
In BAC-1xx36 rmware R1.3.0.4 and earlier, the branch code section
(ending the common code) is somewhere around line 511 and looks
similar to:
REM PERFORM APPROPRIATE SECTION OF CODE BASED ON
FLEXSTAT CONFIGURATION
IF APP_MAIN_TYPE = AHU THEN
GOTO AHU_CODE
ELSE IF APP_MAIN_TYPE = FCU THEN
IF APP_SUB_TYPE = PIPE2 THEN GOTO FCU_2_PIPE_CODE
IF APP_SUB_TYPE = PIPE4 THEN GOTO FCU_4_PIPE_CODE
ENDIF
END
In a BAC-1xx30, rmware R1.3.0.4 and earlier, because there is nothing
specic to applications other than the AHU, there is no branch code
section. However, there is the AHU_CODE label.
Aer the common code, the appropriate application specic section
should be copied, modied as necessary, and running as well.
NOTE: Customized programs are the responsibility of the user. KMC
Controls does not provide support for such programs.
