JPH02214906A - Working state confirming system for action controller of control panel - Google Patents

Abstract

PURPOSE:To confirm whether or not an operating command is normally carried out by using a means to receive an action start report signal from an action controller (sequencer) and to display it and a means to receive and display an action end report signal. CONSTITUTION:When a sequencer receives an action command and starts a forward action of a belt, for example, the sequencer sends an action start report signal via a microcomputer system. This signal is received via a control panel POD and a fact that the sequencer actually started an action is displayed by performing the reverse display (reverse of color) of a numeric character '4,000' set adjacent to the left of a 'forward' part. In the same way, the action end report signal is received via the panel POD when the sequencer is through with its forward action. Then a numeric character '4,010' adjacent to the right of the 'forward' part is reversed and displayed. Thus it is possible to confirm via the panel POD whether or not an operating command is normally carried out or not.

A microcomputer system 1 controls these operations.

[Problem to be solved by the invention]

The programmable operation display proposed by the present inventors has been described above as a conventional operation panel, but as is already clear, such an operation panel constantly displays all operation items on the panel surface for operation. Rather, the operation items of a specific group corresponding to the sequence are displayed as one screen unit on the panel surface for operation.

Now, such conventional operation panels only unilaterally output key operation commands operated on the panel to the sequencer via the microcomputer system, and the sequencer actually starts operating in response to the output key operation commands. There is no way to check whether the sequencer is running or not, or whether it has completed its operation after it has started.

For this reason, if the sequencer is located far away from the operation panel and the operator cannot visually check whether the commands he or she operated have been executed normally on the sequencer, , there was a problem in that it was accompanied by anxiety about issuing the next operation command.

An object of the present invention is to solve the problems of the prior art, and to solve the problem of the sequencer being located far away from the operation panel, so that the operator can check whether the operation commands issued by him/her are correctly executed on the sequencer. An operation control device (sequencer) on the operation panel that enables confirmation on the operation panel even when the operation cannot be confirmed directly with the naked eye, so that the next operation command can be issued without anxiety.
The purpose of this invention is to provide a method for checking the operating status of the system.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an operation panel that is a programmable operation display, in which an operation control device near a key switch corresponding to an operation item reports that the operation control device has started an operation corresponding to the key switch. A means for receiving and displaying a report signal and a means for receiving and displaying an operation completion report signal that reports when the operation is completed are provided.

[Effect]

On the operation panel as a programmable operation display, the operation control device is activated in response to an operation command output to the operation control device (sequencer) via the CPU by operating a switch corresponding to an operation item, or spontaneously. When the operation starts the operation corresponding to the operation item, the operation start report signal display means receives and displays the operation start report signal, and when the operation is completed, the operation start report signal is notified to that effect. The operation completion report signal display means receives and displays the operation completion report signal reported by the operation control device.

〔Example〕

The present invention will now be described in detail with reference to the drawings.

FIG. 3 is a front view of the operation panel (POD) used in the present invention. In this figure, the same or corresponding parts as in FIG. 2 are given the same reference numerals. 6 is a transparent touch key, 8 is an operation switch, 8a is one of them, output key 212 is a display lamp, 21 is a name plate marked with "Sequence number", and 22 next to it is a number as a sequence number. The display section that actually displays the variable (in this case, the number 3 is displayed as the sequence level), 23 is the name plate of each step that constitutes one program sequence as a whole (in this case, one sequence is 5 ).

In the case of the sequence for column 3, step 1lhl is "belt", step l1h2 is "gate", and step column 3 is "belt".
"Gun", step number 4 indicates "Solenoid", etc.

Regarding the "belt", its operation items include "forward rotation" and "reverse rotation". The number 4000 written to the left of "normal rotation" indicates the operation command address, and the number 4010 written to the right indicates the operation completion address. These address data are sent from the sequencer to the operation panel when the sequencer mainly issues an operation command to the automated equipment or completes the operation. When received on the operation panel side, these characters (4000 and 4010) can be flickered or their colors can be reversed to display this fact.

When manually sending an operation command from the operation panel side, press the "forward rotation" part, which constitutes a transparent switch, and the forward rotation operation command address (another address different from 4000) will be sent. It is sent to the sequencer via the CPU.

Since these operation command addresses are data assignments assigned on the sequencer side, data can be exchanged between the sequencer and the operation panel using such address data.

When the normal rotation operation is completed on the sequencer side, an operation completion address 4010 is sent from the sequencer to the operation panel side via the CPU.

Actually, when operating manually from the operation panel side,
If it is a "forward rotation" section, the transparent switch that makes up the "forward rotation" section only performs the selection operation, and the actual sending of address data is
This is done by operating the output key 8a of the operation switch B. Further, at this time, the number of transparent switches to be selected is not limited to one, and a plurality of transparent switches may be selected at one time. If multiple items are selected, of course, by operating the quantity key 8a,
The selected pieces of data are sent out.

For example, in addition to the "normal rotation" part, the "gun" part of step N [L3]
If the user selects the operation item "pressurization" belonging to ``pressure'' and operates the output key 8a of the operation switch 8 after completing the selection, address data corresponding to both of the selected transparent switches will be sequentially sent out. In the selected "pressure" section, the "pressure" section may be displayed in a flickering manner as shown in the figure to indicate that it has been selected.

By the way, let me explain, what is the 8 mark on the operation switch 8? The switch marked is a switch for scrolling the display on the operation panel. In Figure 3, sequence 11h
Although 1 to 5 are displayed as step blocks belonging to sequence block 3, there are actually many more steps belonging to sequence block 3, and due to the size constraints of the panel surface, only 5 step blocks can be displayed. If not, mark the steps not shown with 8 marks. You can scroll the display by operating the switch marked.

In short, in FIG. 3, all steps belonging to one sequence and their action items are displayed on the panel surface, and it is possible to operate each action item and to display whether or not the action is active. To give a supplementary explanation, if it is a "normal rotation" section, it is possible to display that the operation command has been sent by inverting the display color of the "normal rotation" section.

When the sequencer that receives the operation command actually starts normal rotation of the belt, the sequencer sends an operation start report signal to that effect via the microcomputer system, which is received by the operation panel POD and The number r4.000J to the left of the "normal rotation" portion is displayed in reverse (reversed color) to indicate that the sequencer has actually started its operation.

Similarly, when the sequencer completes the forward rotation of the belt,
The sequencer sends an operation completion report signal to that effect via the microcomputer system, so this is sent to the operation panel PO.
When received at D, the number r4010J on the right side of the "normal rotation" section is displayed in reverse (reversed color) to indicate that the sequencer has actually completed its operation.

Needless to say, if the sequence floor changes from 3 shown in the figure to another number (by operating the "Sequence Floor" name plate 21), other step names and operation items will appear on the panel surface accordingly.

FIG. 1 is a flowchart showing the flow of operations performed by a CPU (microcomputer system) when implementing the present invention. The chart consists of steps 81 to 16 as shown.

This will be explained below. In steps Sl and S2, the CPU reads the key power and determines whether there is key power.

If there is a key input, it is necessary to know which of the various keys has been input, so first proceed to step S3, determine whether there is a key input (21 in Figure 3) in the sequence, and If so, proceed to step S4.

In step S4, the display on the operation panel is changed to a step display corresponding to the sequence floor. and step S5
Now, clear the operation switch information previously stored in the memory (RAM4 in Figure 2). By operating the output key 8a, the switch information is read out from the RAM 4 and sent to the sequencer).

If it is determined in step S3 that there is no key manual power on the sequence floor, the process proceeds to step S6, where it is determined whether there is any operation switch input, and if so, the process proceeds to step S7; if not, the process proceeds to step S9. In step S7, a display corresponding to the operation switch is displayed on the operation panel, and in the next step S8, the operation switch information is stored in the memory (RAM4 in FIG.
).

In step S9, it is determined whether or not the output key (82 in FIG. 3) is input. If so, proceed to step 310.

In step SIO, it is not possible to determine whether there is operation switch information stored in the memory in step S8, so it is possible that only output key 8a is operated by mistake even though no operation switch has been operated at all). Step 31
Go to 1. If not, the process advances to step S12. Step S
At step 11, the switch address (or address lI&L) corresponding to the operation switch is output for the sequence.

In step 312, it is determined whether or not the switch II&l (or address group) corresponding to the operation switch in step Sll has been output, and if so, the process advances to step S13 to wait for an operation command signal.

If the operation command signal is received in step S13, the process advances to step S14. In step 514, it is determined whether an operation completion signal has been received, and if the operation completion signal has not been received, the process proceeds to step 315 and an operation command signal is displayed.

If the operation completion signal is received, the process advances to step 316 and the operation completion signal is displayed.

〔Effect of the invention〕

According to the present invention, the sequencer is located far away from the operation panel, so that the operator cannot visually check whether the commands he/she operated are correctly executed on the sequencer. Even in cases where
This has the advantage of being able to confirm this on the operation panel and issuing the next operation command without any anxiety.
