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. (Detection cycle 2 ms)
External control input must be enabled to perform external control.
( Refer to “4.9.7 Setting of external control input enable/disable”.)
The status of the BP4620 can also be monitored by reading the output signal from the external control
I/O connector. (Switching cycle 0.1 ms)
The sequence step synchronized output signals are output from the external I/O connector.
( Refer to “2.4.4 Connection to external control I/O connector”.)
After the external signal input level was changed, several tens of ms might be required for the controller
to execute a function as a maximum response time. “Output ON/OFF” additionally requires approx.
10ms for a response of a relay device.
Table 4-20 lists the functions of each pin.
Table 4-20. Functions of External Control I/O Connector
Pin No. Input/Output Function
1 Output
Outputs the power on/off status.
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
Output off.
Upon detection of the falling of the input signal, switches off the output.
12 Input
Output on.
Upon detection of the falling of the input signal, switches off the output.
13 Input
Sequence start.
Upon detection of the falling of the input signal, starts the sequence.
14 Input
Sequence stop.
Upon detection of the falling of the input signal, stops the sequence.
15 Input
Sequence hold.
Upon detection of the falling of the input signal, pauses the sequence.
16 Input
Sequence branch trigger 0.
Upon detection of the falling of the input signal, jumps to the step specified with BRANCH0.
17 Input
Sequence branch trigger 1.
Upon detection of the falling of the input signal, jumps to the step specified with BRANCH1.
