PROBLEM TO BE SOLVED: To provide a programmable controller capable of translating a user program by aligning/compressing it into execution program code with high execution efficiency optimum for control. SOLUTION: Concerning the programmable controller capable of controlling a controlled system according to the user program written from a peripheral device 11, this device is provided with a translation program memory 10 for translating the user program to the execution program code together with a computing element 3 using a general-purpose microprocessor and a system program memory 4 for storing a system program and this translation program memory 10 translates the user program by aligning/compressing it into program code with high execution efficiency optimum for the control of PLC by retrieving and editing the program corresponding to a previously registered pattern so that scan time can be shortened. Further, by making the translation program memory 10 reloadable, the user program of another machine type can be run as well.
