Abstract

PURPOSE:To decrease a load to a microprocessor of a programmable controller by providing a reservation dedicated temporary storage memory and a pointer setting memory, so that a positioning work can be executed by a control of only a positioning device. CONSTITUTION:When a positioning work start command data is sent from a microprocessor 2 of a programmable controller 1, a microprocessor 8 of a positioning device 3 receives it, and starts a processing. The processor 8 decides whether the received command data is a positioning start command or not, and in case of the positioning command, a head data No. and a pointer of a positioning work reservation data which has been set by the processor 2 in advance are brought to an access from a temporary storage memory 52 and a pointer setting memory 5b, and a positioning work is executed. When the work has been ended, the pointer is substracted by '1', the positioning work is executed by reading out the next data No. from the memory 5a, and thereafter, the operation is repeated until the pointer shows '0'.

Next, the operation will be explained. A positioning work start command is transmitted from the microprocessor 2 of the programmable controller 1 to the microprocessor 8 of the positioning device 3,
When the data is read into the work start data NO register 4, the microprocessor of the positioning device 3 is knitted from the work data in the secondary storage memory 9 to start data N.

Read out and start positioning work. When the work is completed, end data is set in the register 6, and the microprocessor 2 of the programmable controller 1 reads the information. When the microprocessor 2 continues to perform positioning work, it transmits a positioning work start command and 1 positioning start data NO to the positioning device 3 as in the previous time. Thereafter, the above-described operations are repeated to execute one positioning operation.

[Problem that the invention seeks to solve]

Conventional positioning devices have one temporary storage memory within the device.
Therefore, the programmable controller and the positioning device had to access the work start data and work end data for each work based on the positioning work start data numbers (multiple numbers) that were known in advance.
There is a problem in that extra processing time not directly related to the positioning work is required between operations, and smooth slow movement cannot be performed.

This invention was made in order to eliminate the above-mentioned interpolation point, and the data number for starting positioning work, which is known in advance, is registered in the temporary storage meso for work procedure reservation data in the positioning device before the start of work. By registering a pointer representing the number of reserved data in the pointer setting memory, the reserved work can be smoothly controlled by only the positioning device, without the control of the microprocessor in the programmable controller. The purpose of this invention is to obtain a positioning device that can

[Means for solving problems]

A positioning device equipped with a work procedure reservation function according to the present invention adds a temporary storage memory for work procedure reservation data and a pointer setting memory to a conventional positioning device, and also controls continuous positioning work only by the positioning device based on the data. It has been made possible.

[For production]

The positioning device according to the present invention has additional temporary storage memory dedicated to reservation data and pointer setting memory as its work procedure reservation function, and allows positioning work to be performed by control of the positioning device alone, thereby allowing positioning control that is known in advance to be performed. Since it can be operated continuously by a single command, the load on the microprocessor of the programmable controller can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 indicates programmable controls o-, y,
2ta Florama pull controller 910 microprocessor, 3 is a positioning device h5'' is a temporary storage memory for positioning work reservation data, 5b is a pointer setting memory, 6
This is a register for line work completion data.

The configuration of the programmable controller and positioning device is the same as the conventional one, as shown in FIG.

Next, the operation will be explained. As shown in FIG. 4, when positioning work start command data is sent from the microprocessor 2 of the programmable controller 21, the positioning device 30 microprocessor 8 receives the data and starts processing. Positioning device 30 Microprocessor 8
determines whether the received command data is a positioning start command or not, and if the result is other than a positioning start command, the process ends. As a result of the above judgment, in the case of a positioning start command, the first data number and pointer of the positioning work reservation data set in advance by the programmable controller 10 and the microprocessor 2 are transferred to the work reservation data temporary storage memory 5a.
is accessed from the pointer setting memory 5b to execute positioning work.

When the work is finished, reduce the pointer by 1 and the pointer becomes O.
If it is not indicated, that is, if there is only reservation data, the next data N is stored from the work reservation data temporary storage memory 5a.
o is read and 1 positioning operation is executed. Thereafter, this operation is repeated until the pointer indicates 0 and until there is no more reserved data. When the reserved data runs out, work end data is set in the register 6. The microprocessor 2 of the programmable controller 1 accesses the completion data and issues the next command after recognizing the completion of the work. In return, the data sent from the microprocessor 2 of the programmable controller 1 is judged, and if it is not a positioning work start command, the process is terminated, and if it is a positioning work start command, the above-mentioned operation is repeated.

〔Effect of the invention〕

As described above, according to the present invention, positioning work procedures can be reserved in the temporary memory in the positioning device by registering them all at once.
Since the configuration is configured so that positioning control can be performed only by the positioning device based on the pointer setting, the number of inputs of one work start command is reduced, and the load on the machine programmable controller is reduced due to the reduction in the number of inputs. , the positioning work of a plurality of patterns can be performed without wasting time, resulting in high efficiency.
