<P>PROBLEM TO BE SOLVED: To form relation between an existing external line and inside of an input/output device by connecting a removed existing external line to a renewed external signal input/output device. <P>SOLUTION: The removed existing external line 1 is connected to the external signal input/output device loaded with a renewed input/output signal control computer 3. An external address setting terminal 10 is connected to the control computer 3, and I/O port address and external equipment address of floors following the predetermined floor order are input in order, and stored in an address data memory 6 through the computer 3. The control computer 3 has an I/O port 5 having ports corresponding to the number of existing external line, and when the control computer 3 receives an external equipment input signal from the external equipment in order of the predetermined floor order, the control computer 3 rewrites relation between the external equipment of each of the floors and port NO on the basis of the port NO of a floor recognized in order of the predetermined floor order from the address data memory 6 and the port NO of the external equipment input signal passed through the I/O port. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
