Abstract

PURPOSE:To suppress bad influence to be exerted upon the processing time of a working device even if a device whose power supply is disconnected exists by previously generating a poling command whose time-out monitoring time is remarkably shorter than that of a write command to an output request to a device in a no response state. CONSTITUTION:A control device 2 stores a device in a no response, i.e., a device detected at its time-out by a preceding command 61, in a device state storage part 23. At the time of recognizing an output request to the device, a poling command 70 is generated prior to the generation of a write command. When a response from the device to the added poling command goes to time out, the generation of the write command is suppressed and abnormal end is informed to a processor. At the time of returning a normal response to the poling command 70, the write command 62 is continuously generated.
