Abstract
PURPOSE: To prevent the entire control from deteriorating and the time of arithmetic from increasing by sufficiently displaying the functions of a programmable controller by providing an analog signal input part with a constant which can be set and an arithmetic part for arithmetic processing.
CONSTITUTION: Every time an analog signal is input from an external process, provided signal adjustment part 10 processes it and the processed signal is input to multiplexer part 11. Under the command of arithmetic control part 30, multiplexer part 11 selects one of signals at point N and applies to A/D converting part 13 to read the digital conversion result by control part 30 and a conversion constant and the kinds of the conversion expression corresponding to the input point are read out from constant setting part 31 to execute arithmetic indicated by the next constant. According to an indication from address indicating part 15 corresponding to the input point, the arithmetic result is written in output signals storage part 14 and commands are supplied from control part 30 to multiplexer part 11 one after another to output data from output data buffer part 16 via storage part 14.
