DEVICE FOR VERIFYING PLC INSTRUCTIONS BY USING VIRTUAL PLC SIMULATOR

摘要

The present invention relates to a device for verifying PLC instructions and, more specifically, to a device for verifying PLC instructions by using a virtual PLC simulator. The device for verifying PLC instructions according to the present invention comprises: a virtual PLC simulator part for providing a virtual PLC system environment and outputting the operation result of PLC instructions executed in the virtual PLC system environment; a PLC instruction testing part for generating PLC instructions depending on a testcase to transmit the same to the virtual PLC simulator and comparing the operation result of the PLC instructions by the virtual PLC simulator with the testcase to verify the PLC instructions; and a PLC communication part for converting the communication protocol of the PLC instructions into the communication protocol of the virtual PLC system environment. According to the present invention, an environment for verifying the PLC instructions can be constructed more easily than ever, and time required to verify the PLC instructions can be reduced greatly.;COPYRIGHT KIPO 2016
