Abstract

PURPOSE:To omit an exclusive input part for a RUN command or the like and to produce a sequencer economically by using a process input part as an input part for a RUN command signal and a STOP command signal and forming a detecting means for said inputs. CONSTITUTION:The sequencer is formed by a control means (CPU)1, an input device 2, an external apparatus 3, etc. and the process input part 4 in the input device 2 is used as the input part for a RUN command signal and a STOP command signal to input these signals, The RUN and STOP commands are detected by a program stored in the CPU1 and the sequence of the external apparatus 3 is controlled by the CPU1. When the STOP command signal is inputted, the operation of the external apparatus 3 is stopped. Consequently, the exclusive input part for inputting the RUN and STOP command signals can be made unnecessary and the sequencer can correspond to various types of input apparatuses.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sequencer, and particularly to a sequencer in which a run command signal and a stop command signal are inputted from a process input section.

[Prior art]

FIG. 1 shows a sequencer according to the prior art.

In the figure, I is a CPU as a control means, 2 is an input device located between the CPUI and an external device 3, and the input device 2
has a plurality of process input units 4, 5°, . . . to which the external device 3 is connected. Also, 6 is the above C
Indicate a switch section that outputs a run command signal and a stop command signal to the PUI.'' Then, when the switch section 6 is operated and a run command signal is output to the CPU 1, the CPU 1 sends a control signal to the external device 3. Output and execute sequence control.

On the other hand, when the switch section 6 is operated and a stop command signal is output to the CPU 1, the CPU 1 stops the operation of the external device 3.

By the way, in the conventional sequencer configured in this way, a dedicated switch section 6 was provided for inputting the run command signal and the stop command signal to the CPU, and therefore had the drawback of being expensive.

[Summary of the invention]

The present invention has been made in view of the above-mentioned drawbacks of the prior art.
By using one or more of the process input parts as an input part into which a run command signal and a stop command signal are input, and by providing a detection means for detecting the input of the run command signal or stop command signal and outputting it to the control means, it is possible to reduce the cost. The purpose is to provide a sequencer that can be supplied to

[Embodiments of the invention]

Embodiments of the present invention will be described below based on the drawings. Note that the same components as those in the prior art are given the same reference numerals, and the description thereof will be omitted.

However, in the present invention, the process input section 4 serves as an input section for the run command signal and the stop command signal, and the run command signal or the stop command signal is input from the process input section 4.

Further, 11 is a detection means for detecting the input of a run command signal or a stop command signal to the process input section 4, and when the detection means 11 detects the input of the run command signal or stop command signal, it sends a respective message to the CPUI. A detection signal indicating this is output. Actually, the detection means 11 is constituted by a program stored in the CPUI.

The sequencer according to the present invention is constructed as described above, and its operation will be explained next.

First, when a run command signal is input to the process input section 4,
The detection means 11 outputs a detection signal to that effect to the CPUI, and as a result, the CPUI sequentially controls the external equipment.

Next, when a stop command signal is input to the process input unit 4, the detection means 11 outputs a detection signal to that effect to the CPUI, and as a result, the cp'u1 stops the operation of the external device 3.

Thus, according to the present invention, not only is it unnecessary to use a dedicated input section as in the prior art for inputting run command signals and stop command signals, but also the user can input any process input section for inputting run command signals and stop command signals. Since it can be specified as the input part for the stop command signal, the type of input crab knit for that part can be selected (AC.

DC), it is possible to support various types of input devices. Note that a plurality of process input units 4.5. ---
1 may be used as an input section for a run command signal or a stop command signal.

(Effects of the Invention) As explained above, according to the present invention, one or more of the process input sections is used as an input section into which a run command signal and a stop command signal are input, and the run command signal or the stop command signal is inputted. Since the detection means for detecting and outputting to the control means is provided, a dedicated input section as an input section for the run command signal and the stop command signal can be omitted. 1. Therefore, it is possible to contribute to low cost.
