PURPOSE:To facilitate changing input conditions and output conditions by providing a rewritable operation step table, where input conditions and/or output conditions are written for individual steps, in accordance with each sequence command. CONSTITUTION:Output conditions and sequence commands are preliminarily stored in a fundamental operation table area 17, and many rewritable operation step table areas 271-27n where input conditions and/or output conditions are written for individual steps are provided in accordance with individual sequence commands. When a sequence command is accessed from the fundamental operation table in response to the input signal from a controlled system 31, a CPU1 as the control means accesses the input condition and/or the output condition corresponding to each input signal from the operation step table corresponding to this sequence command and outputs them as an output signal. |
