4.6 Control via External Control I/O Connector
Output on/off and sequence execution can be controlled by inputting digital signals to the external
control I/O connector. The step sync output signal is output from the external I/O connector.
The status of the BP4610 can also be monitored by reading the output signal from the external control
I/O connector.
(
Refer to “2.4.4 Connection to external control I/O connector”.)
Table 4-20 lists the functions of each pin.
Table 4-20. Functions of External Control I/O Connector
Pin No. Input/Output Function

0 and 1 indicate off and on, respectively.
2 Output
Outputs the output on/off status.
0 and 1 indicate off and on, respectively.
3 Output
Outputs the overload status.
0 and 1 indicate regular operation and abnormal status, respectively.
4 Output
Outputs the software busy status.
0 and 1 indicate regular operation and busy status, respectively.
5 Output
Step sync output 0.
Outputs bit 0 of the step sync output.
6 Output
Step sync output 1.
Outputs bit 1 of the step sync output.
11 Input
Forced output off.
Upon detection of the falling edge of the input signal, forcibly switches off the output.
12 Input
Forced output on.
Upon detection of the falling edge of the input signal, forcibly switches off the output.
13 Input
Sequence start.
Upon detection of the falling edge of the input signal, starts the sequence.
14 Input
Sequence stop.
Upon detection of the falling edge of the input signal, stops the sequence.
15 Input
Sequence hold.
Upon detection of the falling edge of the input signal, pauses the sequence.
16 Input
Sequence branch trigger 0.
Upon detection of the falling edge of the input signal, jumps to the step specified with
BRANCH0.
17 Input
Sequence branch trigger 1.
Upon detection of the falling edge of the input signal, jumps to the step specified with
BRANCH0.
