ABSTRACT:
A programmable controller has a multi-purpose processor such as an MPU and an application specific control device such as an ASIC (application specific integrated circuit). When the MPU requests the ASIC to execute a user program and the ASIC is activated, the MPU executes an event process while the ASIC executes the requested user program. When the MPU requests the ASIC to execute a DMA transfer process in an input/output refresh process and the ASIC is activated, the MPU executes an event process while the ASIC executes the requested DMA transfer process.
