Abstract

PURPOSE:To simplify the constitution of a controller, by indicating one of two controlling means by indicators which indicate a measured value and a target set value and switching and setting displayed values by a manual and performing monitor and operation equivalent to those of plural indicating and operating parts by one indicating and operating part. CONSTITUTION:One controller incorporates two PID controlling operation arithmetic elements 13 and 14, and one display and operating part 12 is provided on the surface of the controller. A switching part 15 is provided between elements 13 and 14 and the display and operating part 12, and a push-button switch 7 of the display and operating part 12 is operated to set each switch of the switching part 15 to the A side, and the local set operation in the side of the element 13 is possible by a target set value manual operation dial 4 when the set mode is in the L side. Simultaneously, a measured value PV1 and a target set balue SV1 related to the side of the element 13 are indicated by a measured value needle 5 and a target set value needle 3 respectively. Thus, the button switch 7 is switched to perform monitor and operation equivalent to those of plural display and operating parts by one display and operating part 12, and the constitution of the controller is simplified.

に、誤操作防止もはかることができる。According to the embodiment of the present invention described above, the instruction/operation switching section 15 is provided, and the switching section 15 is switched by operating the push button switch 7, so that the local setting operation on the calculation element 13 side or 14 side can be changed to manual target setting operation. This can be done using the operation dial 4, and the measurement value and target setting value can be specified, so the instructions and operation section of the controller are required for one controller, and the adjustment operation calculation elements are required for two controllers. (or for two or more machines), the operator can easily operate and monitor the two machines by operating the push button switch 7. This has a great effect on safe operation of the control system. Further, since the contents displayed on the digital display 6 can be changed by operating the push button switch 7, the equipment configuration can be simplified and erroneous operation can be prevented.
