Control Programs
Program Cycles, Program Files, and Factory Settings
Program Cycles
According to the program philosophy, input signals are queried in brief, irregular intervals. Because of how the
program is designed, up to 300 μs may elapse between the activation of an input signal (IN1 to IN10) and the time
dispensing actually begins.
The analog signal for controlling variable pauses is queried as quickly as possible, though at least once every 10 ms.
The queried input values remain constant until the next query (i.e., for no more than 10 ms; see diagram).
Program Files
The control programs for the PICO controller are created as TXT files using a PC. They are saved on an SD card and
then loaded into the PICO controller’s memory from the card. The following sample programs are good examples of
the structure of the program:
• General data block for unit specification (unique for each program)
• Information specific to each channel (unique for each channel)
• Information specific to lines and blocks (for each line or block)
A program part for a channel can consist of 1 to 99 lines.
