<p>PURPOSE:To attain the optional output of a digital output signal just with selection of the No of a table parameter by providing a storage which turns the relationship between the output items and their corresponding output contact Nos into a table and stores this table. CONSTITUTION:A CPU 12 operates a manipulated variable serving as an output signal based on the target value and the controlled variable of a control subject fetched from an analog input part 13 or a digital input part 14. The manipulated variable that is finally outputted as an analog signal is transmitted to an analog output part 15. At the same time, the output of various commands, and alarms, etc., are sent to a digital output part 16 as the digital signals. The part 16 outputted the signal of the output item (table parameter) which is previously selected out of a table contained in a RAM 18. As a result, the digital output is directly outputted to the outside from the table parameter with set-up of a No and with no programming.</p> |
