ectrically erasable and programmable ROM) and DIP
It was set by writing to the switch. FIG. 3 shows a main configuration of a conventional communication device. The device control package (also referred to as a function block package) 10 is mounted on a back panel 14 using a connector 12 in a bookshelf format together with other packages (not shown). The device control package 10 includes a LAN interface (not shown), and is connected to an external LAN 16 via the LAN interface.

The device control package 10 has a storage device 18 in which device-specific data such as an IP address is set before starting operation. At this time, a DIP switch is used as the storage device 18 when the amount of data to be set is small, and an EEPROM is used as the storage device 18 when the amount of data to be set is large.
Since the amount of data differs depending on the device, an appropriate storage device suitable for the device is selected at the time of design.

The device control package 10 includes a CPU
(Central processing unit). EEP is used as the storage device 18 described above.
When the ROM is used, the control unit 20 in the package is used.
The device-specific data is fetched from the external work station 22 through the external device and written into the EEPROM.

[0005]

However, in the above-described conventional communication device, when the device control package is replaced due to a failure, repair, version upgrade, or other reasons, device-specific data such as an IP address is transmitted. You have to set it again. As a result, there have been problems such as an increase in the number of steps at the time of replacement work and an increase in malfunction of the apparatus due to an incorrect setting.

Therefore, there has been a demand for a communication device that does not need to reset device-specific data when a device control package is replaced.

[0007]

Therefore, according to the communication device of the present invention, a storage device in which device-specific data such as an IP address is recorded is stored in a sub-unit separate from a device control package having a communication interface. It is characterized by being mounted on a board.

Further, according to the communication device of the present invention, a communication device in which a device control package having a communication interface is mounted on a back panel using a predetermined connector, wherein device-specific data such as an IP address is stored. The recorded storage device is mounted on a sub-board separate from the device control package, and the sub-board is mounted on a back panel using a predetermined connector.

With this configuration, when replacing the device control package, the sub-board can be left mounted. Therefore, since it is not necessary to reset the device-specific data, setting man-hours and malfunctions can be reduced.

In the communication device according to the present invention, it is preferable to use a nonvolatile storage device.
