Abstract
To provide a programmable controller for enabling a device value to be set and changed, and also referenced, easily and accurately. A programmable controller has a main unit CPU, a storage section, a display CPU, a display section, and a key section. The state of the key section is stored in a key information buffer of the display CPU. A control section of the display CPU sets and changes the device value stored in the storage section through the main unit CPU and causes the display section to display the device value stored in the storage section based on key information in the key information buffer.
