<p>A programmable controller constituted of a main processor (11) which executes the function instruction of sequence program and the control program (12a), and a bit operation controller (17) which executes the basic instruction of the sequence program. The bit operation controller (17) includes a register (17a) that stores signal conditions of predetermined signals, and a condition detector circuit (17b). The signal condition of the condition detector circuit (17b) that satisfies a condition set by a particular function instruction, is sent to the main processor (11), in order to send an interrupt signal for executing the particular function instruction. Then, the function instruction processes the signal condition without waiting time.</p> |
