Abstract

PURPOSE:To execute a test of all programs related to the process input/output, even in a state that a PI/O (process input/output device) is not connected to a host computer, by providing a testing device containing a process input/output simulator analyzing device. CONSTITUTION:The titled controller is provided with a testing device 5 containing a process input/output simulator analyzing device 51 for simulating an input/output procedure extending from a PI/O 4 to a plant and its method, and a switching device 6 for connecting alternatively the PI/O 4 and the testing device 5 to a host computer 1. In this state, when the PI/O 4 is not connected, the testing device 5 is connected instead of the PI/O, an input and an output are executed actually to and from the testing device 5, and an operation confirming test is executed. In such a way, the host computer 1 can execute an input and an output in entirely the same way as the case when the PI/O 4 is connected, therefore, prior to a hardware test of the PI/O 4, the operation confirming test of all programs and a related device related to an input and an output of the PI/O in the host computer can be executed.
