いる。A unique address is set for each terminal, various controlled devices, sensors, etc. are connected to each terminal, and control signals or monitoring signals are transmitted and received between the terminals. Figure 2 shows an example of a 7-bit transmission signal. For example, the source terminal address, the destination terminal address, the number of bytes of transmitted data, the transmitted data, and the check code are expressed in a predetermined number of bits. It is configured as a signal.

市販されている。In recent years, the demand for this type of system has increased, and terminal devices have become integrated into one chip. However, if the analog output of the sensor is converted to A/DI and then input to the terminal '#deaf, Since the cost of an A/D converter is high, terminal ICs with a built-in A/D converter of about 4 bits have recently been commercially available.

Since there are not many sensors that require D conversion, the A/D input terminal is often vacant.

Connect a DC power supply to one of the input terminals via a voltage dividing resistor,
The above address is set by the output of the A/D conversion, and by using this A/D converter in a terminal device with a built-in A/D converter, it is possible to avoid the expensive IP address as in the past. The terminal address can now be set using only a fixed resistor or variable resistor without using a type switch. It has a strong VF characteristic.

It has a built-in A/D converter for converting analog signals into digital signals. Connect the DC power supply VCC to one of the A/D input terminals of this terminal via two fixed resistors R1 and R2 for voltage division, and further internally connect the output of the A/D converter to the address input. This allows the terminal device address to be set. Furthermore, instead of the fixed resistors R, , R, a variable resistor VR may be used as shown in FIG.

すばよい。When actually setting addresses, use resistors R1 and R2 whose resistance values have been adjusted in advance to correspond to multiple addresses.
You can prepare a set of resistors and select and install the appropriate pair of resistors during construction, or you can install extra resistors in advance and cut the desired resistor to set it. Five too. When using the Mushita variable resistor VR, mark the address on the dial scale (1).

という利点がある。[Effect of the Invention 1 As described above, the present invention provides an A/D converter built into an r-terminal device for Δ/D conversion of a sensor output in a multiple time transmission system that controls a load and monitors a single sensor output. By using an A/D converter, connecting a DC power supply to one of its input terminals via a voltage dividing resistor, and setting the terminal 7F-less using the A/D conversion output, it is expensive. There is no need to use an IP type switch (but it has the advantage of being able to set the terminal device address with a fixed resistor or variable group bias).
