端子（図示せず）、例えば、コネクタを設けてある。In FIG. 3, a PC 10 has a one-to-one two-way communication connection function unit 11 capable of relatively long-distance communication.
For example, a communication connection function unit using an IC for the RS-232C standard is provided, and the two-way communication connection function unit 11 allows the PC 10 and a plurality of MPUs 21 (1) to 21 (n) to be connected.
The communication between the MPUs 21 (1) to 21 (n) and the communication between the MPUs 21 (1) to 21 (n) are performed via the communication path 31A, the communication conversion unit 30, and the communication path 31B, so that a predetermined control process, for example, The air conditioner and the like of the distributed arrangement type air conditioner (not shown) are controlled and processed. A connection terminal (not shown), for example, a connector, corresponding to the connection configuration of the two-way communication connection function unit 11 is provided at a location where the two-way communication connection function unit 11 is connected to the communication path 31A.

信信号が微弱なため、ごく近距離の通信しか行えない。In the MPUs 21 (1) to 21 (n), only the input ports 21 (1) a to 21 (n) a and the output ports 21 (1) b to 21 (n) b are used for communication. Since the signal is weak, only short-range communication can be performed.

いものである。That is, a communication signal transmitted from the PC 10 to the communication path 31A is an RS-2 that can perform relatively long-distance communication.
Since the communication signal is a communication signal conforming to the 32C standard, and the communication signal transmitted through the communication path 31B is a communication signal conforming to the standard of an IC for an interface driver that can perform only medium-range communication, FIG. Are drawn short, but in practice, the communication path 31A can be a long communication path, and the communication path 31B can only be a short communication path.

The communication between (n) is converted so as to match the difference in the protocol according to each communication standard, and each MPU 21
The communication converter 30 for intensifying the communication signals from (1) to 21 (n) and enabling mutual communication is indispensable. The communication configuration based on the communication address and the like is the same as the communication configuration according to the second conventional technique.

For example, by connecting to the communication path 31A via a connector for the RS-232C standard, the communication section 30 and the communication path 31B can be configured so that complicated communication components can be removed.

になる。In the configuration of the third prior art, it is indispensable to provide a complicated communication component including the communication conversion unit 30 and the communication path 31B, and the device configuration cannot be made simple and inexpensive. Therefore, such a disadvantage can be solved by the configuration of the fourth related art.

All of the MPUs 21 (1) to 21 (n) have a one-to-one two-way communication connection function unit 24 capable of relatively long-distance communication.
(1) to 24 (n), for example, since it is necessary to provide a communication connection function unit using an IC for the RS-232C standard,
There is an inconvenience that the cost is increased by the change to the two-way communication connection units 24 (1) to 24 (n).

In (24) to (n), in order to enable relatively long-distance communication, a voltage across both positive and negative is used.
Since power consumption increases, a power supply (not shown) for supplying the power must be changed to a power supply having a large power capacity, and the cost of the change increases. The inconvenience that it cannot be provided arises. For this reason, there is a problem that it is desired to provide a control processing group device that does not have such inconveniences and a device that uses the control processing group device.
