Abstract
A communication control apparatus for enabling an A/D converter to be shared among a plurality of input units to eliminate the work for newly installing an A/D converter for a new sensor when the sensor is added. A communication control apparatus is provided which includes input/output lines for connecting an input/output unit and a central control unit to each other and used for transmitting data, the central control unit is provided with an analog to digital converter and is used for carrying out processing of load control based on input data coming from the input/output lines, and the input/output unit. An input side of the input/output unit is connected to sensors and an external switch whereas an output side of the input/output unit is connected to a load such as a motor. The communication control apparatus wherein the input/output lines include transmission lines B1 and B2 for transmission of digital data and a transmission line A1 for transmission of analog data, and the input/output unit transmits specific data indicating a channel of analog data through the transmission line B1 when transmitting the analog data.
