Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a digital controller capable of lessening operations at an input and output checking test and shortening a period of the input and output checking test. SOLUTION: A test connector 14 and switching circuit 13 are arranged on a control board 10 for performing input and output between a digital controller and a plant in order to control the plant. The switching circuit 13 switches a connecting destination of an input and output circuit 11 from a regular connector 12 to the test connector 14 when a test tool cable 31 of a test tool 30 is connected with the test connector 14, and makes the test tool 30 connect with the input and output circuit 11. Thus, an input and output checking test for the control board 10 can be carried out by the test tool 30. COPYRIGHT: (C)2009,JPO&INPIT
