4.5 Control Using External Control I/O Connector
Digital signals that are input to the external control I/O connector can be used to control sequences and the
output on/off setting. (Detection cycle 2 ms)
The status of the APS-1102A can be monitored by reading the output signals from the external control
input/output connector. (Switching cycle 0.1 ms)
The sequence step synchronized output signals are output from the external control I/O connector.
See “3.3.4 External control I/O”.
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 the similar time
for a response of a relay device. These response times may vary.
Table4-13 lists the functions of the connector various pins.
