    • In a temperature controller system, a plurality of temperature controllers that adjust a temperature of a control object are to be connected to a programmable logic controller. One of the temperature controllers includes a PLC communicating portion which exchanges data with the programmable logic controller through a dedicated cable, a serial communication portion which exchanges data with the temperature controllers that are connected in a downstream side, through serial communication cable, and a communication and conversion CPU which controls the data exchange performed between the PLC communicating portion and the programmable logic controller, and which controls a serial communication performed by the serial communication portion.
    • 在温度控制器系统中,将控制对象的温度调节的多个温度控制器连接到可编程逻辑控制器。 其中一个温度控制器包括通过专用电缆与可编程逻辑控制器交换数据的PLC通信部分,通过串行通信电缆与下游侧连接的温度控制器交换数据的串行通信部分,以及通信 以及转换CPU,其控制在PLC通信部和可编程逻辑控制器之​​间执行的数据交换,并且控制由串行通信部执行的串行通信。
