4.2.4.2 Displaying the Status of Binary Inputs and Outputs
To display the binary input and output status, do the following:
• Select 2 (= Status) on the top "MENU" screen to display the "Status" screen.
• Select 2 (= Binary I/O) to display the binary input and output status. (Binary inputs and outputs
depend oh the relay model.)

Lines 1 and 2 show the binary input status. BI1 to BI16 corresponds to each binary input signal.
For details of the binary input signals, see Appendix G. The status is expressed with logical level
"1" or "0" at the photo-coupler output circuit. IO#1 and IO#2 in the table indicates the name of the
module containing the binary input circuits.
Lines 3 to 5 show the binary output status. TP-1 to TP-5 of line 3 corresponding to the tripping
command outputs. Models 203 and 204 are not provided with TP-4 and TP-5. FAIL of line 4
corresponds to the relay failure output. Other outputs expressed with BO1 to BO13 are
configurable. The status of these outputs is expressed with logical level "1" or "0" at the input
circuit of the output relay driver. That is, the output relay is energized when the status is "1".
IO#1 to IO#3 in the table indicate the names of the module containing the binary output relays.
To display all the lines, press the
