1. A controller unit in a programmable controller, the controller unit comprising:
a real-time operating system implementer including first processing circuitry to implement a real-time operating system; and
a general-purpose operating system implementer including second processing circuitry to implement a general-purpose operating system, wherein
the real-time operating system implementer further includes
a receiver to receive instruction data indicating an instruction for changing a power supply state of the general-purpose operating system including activation and deactivation of the general-purpose operating system, and
a power operation circuit to activate the general-purpose operating system,
the real-time operating system implementer activates the general-purpose operating system using the power operation circuit when the receiver receives the instruction data for activating the general-purpose operating system, and
the general-purpose operating system implementer deactivates the general-purpose operating system when the receiver receives the instruction data for deactivating the general-purpose operating system.
