CONTROLLER FOR OPERATING PANEL

摘要

PURPOSE:To execute a control of an operating panel by a simple constitution by providing an exclusive controller for a display, and an input/output part which can handle each LED of a switch/LED output part of a panel, as a contact input/coil output. CONSTITUTION:An indicator controller 21 for controlling an indicator 31, and an input/output part 22 for controlling a switch panel 32 and an LED output part 33 are provided. A pattern corresponding to a character code outputted from a CPU 13 of a programmable controller is read out of a ROM 23 of the controller 21, and a controller 24 outputs it to the indicator 31 and displays it. Also, an inputting circuit/16-point LED outputting circuit 28 of 64 keys of the inputting part 22 scans each switch of a panel 32/an LED output part 33, by synchronizing with a signal generated by a scan clock generating circuit 26, and inputs and outputs a signal successively.
