One-to-One
Program Select
• LIMFNCi-iP
• INFNCi-iP
An input defined as a One-to-One Program Select input is assigned to execute one specific
program. The targeted program is reference by its number (see note).
Program Numbers
A program’s number is determined by the order in which the program was downloaded to the
controller. The number of each program stored in the controller's memory can be obtained
through the TDIR command — refer to the number reported in front of each program name.
When selecting programs with One-to-One Program Select inputs, the program number is
assigned to one specific input and is executed when the input is activated (see example
below).
Before you can execute programs using the One-to-One program select inputs, you must first
enable scanning with the INSELP2 command. Once enabled, the controller will continuously
scan the inputs and execute the program (by number) according to the program number
assigned to the input. After executing and completing the selected program, the controller will
scan the inputs again. NOTE: To disable scanning, enter !INSELPØ or place INSELPØ in a
program that can be selected.
The INSELP command also determines how long the program select input level must be
maintained before the controller executes the program. This delay is referred to as debounce
time (but is not affected by the INDEB setting).
Example RESET ; Return controller to power-up default conditions
DEF proga ; Begin definition of program proga
TFB
; Transfer position of feedback devices
END
; End program
DEF progb ; Begin definition of program progb
TREV ; Transfer software revision
END
; End program
DEF progc ; Begin definition of program progc
TSTAT ; Transfer statistics
END
; End program
TDIR ; Response should show: *1 - PROGA USES 36 BYTES
; *2 - PROGB USES 70 BYTES
; *3 - PROGC USES 133 BYTES
INFNC4-1P ; input 4 will select proga
INFNC5-2P ; input 5 will select progb
INFNC6-3P ; input 6 will select progc
INSELP2,50 ; Enable scanning of inputs with a strobe time of 50 ms
You can now execute programs by making a contact closure from an input to ground to
activate the input:
• Activate input #4 to execute program #1 (proga)
• Activate input #5 to execute program #2 (progb)
• Activate input #6 to execute program #3 (progc)
