<p>PROBLEM TO BE SOLVED: To display required data among communication data on a field bus without adding a program and limiting the number of installed sets. SOLUTION: A required data part among communication data on a field bus 2, e.g. a temperature data part of a temperature sensor 12 of 2CH connecting to an analog terminal device of a node address '03' is preset in a display device 9. Thus, the display device 9 acquires the preset data part among response reply data of the analog terminal device 6 with respect to a data read request from a master unit l, that is, the temperature data of the temperature sensor 12 of 2CH and displays the data on a display section.</p> |
