<p><P>PROBLEM TO BE SOLVED: To reduce the number of testing members required for a test in conducting an instrumentation loop test of a digital controller or the like. <P>SOLUTION: Remote testing equipment for a plant has an interface function for reading an optional digital signal value of internal logic of the digital controller or the like and for transmitting the digital signal value to a LAN 4 for the test in the loop test assuring soundness and accuracy of a circuit inputted to the digital controllers or the like 8a, 8b from a detector 9 measuring the process value of the plant, or the soundness and the accuracy of a circuit outputted to on-site equipment from the digital controller or the like. In addition, the remote test equipment for the plant has a function reading the optional digital signal value of the internal logic of the digital controller or the like without affecting the logic to which a plant control response speed is requested by using an interface for maintenance provided in the digital controller or the like and enabled to transmit the digital signal value to the LAN for the test. <P>COPYRIGHT: (C)2004,JPO</p> |
