ABSTRACT:
A programmable controller device has a main body with a CPU unit and I/O units connected by a bus line and a power unit for supplying power to the main body. The CPU unit has a memory with a user access area which is accessible by instruction of user program. The power unit generates status data related to itself such as its temperature. A data transmission path is provided between the CPU unit and the power unit for transmitting such status data to the user access area.
