<p> The present invention provides a control controller (10) for describing a sequential loop control comprising an input process, a control computation process, and an output process by using a ladder program, and executing the loop control. The control controller (10) is provided with a sequence processor (1), an arithmetic processor (2), and a memory (3). The memory (3) is provided with a ladder program (4) and a loop control program (6). The ladder program (4) comprises a combination of a command and an operand. The sequence processor (1) sequentially reads the ladder program (4). When the command in the ladder program (4) is a sequence command, the sequence processor (1) executes a sequence command. When the command in the ladder program (4) is a loop command, the arithmetic processor (2) executes the loop control program. The loop command is provided with a loop command operand capable of defining at least the input process, the control arithmetic process, and the output process.</p> |
