Switching elements 3 are provided at output terminals 312 and 322 of the address register 31 and the data register 32, respectively.
6 and 37 are connected to the switching terminal t2, and the switching element 36
To 38 common terminals tc, an operation copy data storage unit 3f is connected. Further, the switching terminal t1 of the switching elements 36 to 38 is connected to the diagnostic MPU of the elevator diagnostic device 3.

Next, the operation of the embodiment having such a configuration will be described.

Operation MPU of elevator operation control device 2
When various data relating to the operation of the elevator apparatus 1 are output from the operation data storage unit 2e, these data signals D2 are stored in the operation data storage unit 2c, and the signal connection devices 2g, 3
g, is also stored in the data register 32 via the buffer amplifier 33 at the same time. At this time, the address signal A2 of various data relating to the operation of the elevator device 1 is also stored in the address register 31 via the signal connection devices 2g and 3g.

The address discriminating device 34 receives the address signal A1 input from the diagnostic MPU 3c of the elevator diagnosing device 3 and the address discriminating device 3 from the output terminal 312 of the address register 31 via the switching element 36.
Address signal A from the operating MPU 2e input to
2 is determined to be different. In this determination, when the address signal A1 and the address signal A2 are different signals, that is, when the data of the copy data storage unit 3f is not read by the elevator diagnostic device 3, the output of the address determination device 34 The logical value of the signal is “0”.

When the logical value of the output signal of the address discriminating device 34 becomes "0", the switching elements 36 to 38 are switched to the switching element t2 as shown in FIG. Since the logical value of the signal at the output terminal becomes "1", the address signal A2 stored in the address register 31 and the data signal stored in the data register 32 are copied via the switching elements 36 and 37. The data is input and stored in the data storage unit 3f. At this time, the read / write signal RW2 of the operation MPU 2e is also switched to the switching element 38.

On the other hand, when the address discriminating device 34 determines that the address signal A1 and the address signal A2 are the same signal and the elevator diagnostic device 3 is reading data from the copy data storage section 3f. , The logical value of the output signal of the address determination device 34 is “1”. Thus, the logical value of the output signal of the address determination device 34 is “1”.
, The switching elements 36 to 38 are switched to the switching terminal t1 side, and the address register 31 and the data register 32
The signal line of the read / write signal RW2 is disconnected from the operation copy data storage unit 3f, and the diagnostic MPU 3c can read desired data from the copy data storage unit 3f without any trouble.

As described above, while the diagnostic MPU 3c is reading data from the copy data storage unit 3f, the data written to the operation data storage unit 2c from the operation MPU 2e is stored in the address register 31 and the data register. 32. These data are written into the copy data storage unit 3f together with the switching of the switching elements 36 to 38.

As described above, according to the embodiment, the data written from the operation MPU 2e of the elevator operation control device 2 to the operation data storage unit 2c is stored almost simultaneously in the operation copy data storage unit 3f of the elevator diagnosis device 3.

In the present invention, the address of the operation data storage unit 2c and the address of the operation copy data storage unit 3f do not necessarily have to be the same, and if an address signal is created using a chip selector or the like, It is preferable that the values of the lower predetermined digits match. Further, an address discriminating device for taking in the address signal of the operation MPU is added. When the address signal is the address signal of the operation data storage unit and the logical value of the output signal of the inverter is "1", the address register and the data register are connected. By operating, it is also possible to store only the data in the operation data storage unit in the copy data storage unit and to prevent unnecessary data from being stored.

[0025]

As described above in detail, according to the present invention, the address signal output from the second device is determined by the address signal determining means as to whether or not the address signal is a specific address signal. When the output is determined, the switching element is switched by the switching means so that the data can be read from the copy data storage unit by the second device, and when the output of the specific address signal is not determined, the register is switched by the switching means. The address signal and the data signal stored in
Since the switching element is switched so as to write the data in the copy data storage unit, the data stored in the first device can be almost simultaneously written.
