<p>PURPOSE:To make simulation possible by sequence instructions which are written in a sequence program. CONSTITUTION:When an execution flag memory 0 (25) indicates '0', none of the instructions is placed in simulation operation and normal operation is performed. When the execution memory 0 (25) indicates '1', on the other hand, the simulation operation is performed and the processing is carried out according to the contents of an execution flag memory 1 (26). Namely, when the execution flat memory 1 (25) shows '1', a contact instruction performs operation by setting a contact to '1' (ON) and an output instruction performs operation by forcibly setting an output to '1' (ON). Further, when the execution flag memory 1 (26) indicates '0', the contact instruction performs operation by setting the contact to '0' (OFF) and the output instruction performs operation by forcibly setting the output to '0' (OFF).</p> |
