<p>PURPOSE:To easily simulate an arbitrary control program by rewriting an input/output instruction word described in a control program to the input/output instruction word of simulation information prior to the execution of the control program, and re-storing it in a RAM. CONSTITUTION:All or designated part of the input/output instruction words described in the control program (application program) are rewritten to the input/output instruction words of simulation information corresponding to a command from an operator prior to the execution of the control program, and they are re-stored in the RAM 106. Thereby, the simulation of a desired control program can be performed even when in a state where a process remains being connected to a read I/O terminal by switching switches 301-303 to a simulation terminal side by rewriting the instruction word.</p> |
