Human machine interface included protocol analyzer

摘要

PURPOSE: A human machine interface in which a protocol analyzer is mounted is provided to display information for a communication device with a defect to a touch screen panel, thereby enabling a user to easily recognize a communication state of each connected device. CONSTITUTION: A memory (12) stores receiving protocol frames. A data transmitting/receiving unit(40) transmits and receives data to industry devices through communication drivers. An extraction module(16) extract the receiving protocol frame from response data. A detection module(17) detects whether or not a receiving protocol frame which corresponds to the extracted receiving protocol frame is existed. A conversion module(18) converts a detected communication state result into character data. A display module(13) displays the character data and the response data in a display device.
