PROBLEM TO BE SOLVED: To provide a controller system for suppressing response delay of a positioning device. SOLUTION: A programmable controller 1 includes a change data table 12 in which operation data and a count value of a transmission period are registered, and a device name conversion table 14a in which a memory address and data ID are registered. Data ID and data, which are obtained from the device name conversion table 14a, are registered in a periodic transmission buffer 11 as periodic transmission data. When periodic transmission data is transmitted, next periodic data retrieved from the change data table 12 is registered in the periodic transmission buffer 11. The positioning device 2 is provided with a device name conversion table 14b in which the memory address and data ID are registered, and writes periodic transmission data into a positioning device memory 20 at a memory address corresponding to the periodic transmission data obtained from the device name conversion table 14b.
