Abstract
A controller according to an embodiment includes a memory and a processor. The processor controls an external control target device. The processor includes a controller-function core and a computer-function core. The controller-function core executes a ladder application that reads out I/O data received from the control target device from an I/O memory out of a storage area of the memory, stores a part of the I/O data out of the read I/O data in a shared memory different from the I/O memory out of the storage area, and stores control data to be transmitted to the control target device in the I/O memory. The computer-function core is a core different from the controller-function core and executes a computer application that reads out the I/O data from the shared memory.
Claims4
A controller comprising:
- a memory;
- and
- a processor configured to control an external control target device, wherein
- the processor includes
- a controller-function core configured to execute a ladder application that reads out I/O data received from the control target device from an I/O memory out of a storage area of the memory, stores a part of the I/O data out of the read I/O data in a shared memory different from the I/O memory out of the storage area, and stores control data to be transmitted to the control target device in the I/O memory, and
- a computer-function core that is a core different from the controller-function core and is configured to execute a computer application that reads out the I/O data from the shared memory.
