Abstract
A programmable logic controller performs execution of a program in each set period and repeats the execution of the program. The first device storage stores a device value that is an input value and an output value of the program. The second device storage stores the device value stored in the first device storage in a previous period. In a case in which a reading target preset for a device designated by a monitor request received from an engineering tool is the first device storage, the command processor reads the device value stored in the first device storage after execution of the program in a current period is completed, and in a case in which the reading target is the second device storage, the command processor immediately reads the device value stored in the second device storage. The command transmission/reception element transmits the device value to the engineering tool.
