(7) PERIPHERAL I/F
connector
For communication I/F with peripheral devices.
• Upper LED
Remains flashing: It communicates with the peripheral devices.
OFF: It does not communicate with the peripheral devices.
• Lower LED
ON: Data transmission speed 100Mbps
OFF: Data transmission speed 10Mbps
(8) Internal I/F connector Connector to connect the manual pulse generator/incremental synchronous
encoder, or to input/output the signals.
(Voltage-output/open-collector type, Differential-output type)
(9) 24VDC power supply
connector
The DC power of 24VDC is connected.
(10) Serial number display Displays the serial number described on the rating plate.
(11) MODE LED Indicates the mode of the PLC CPU area.
ON (green): Q mode
(12) RUN LED Indicates the operating status of the PLC CPU area.
ON: During operation with the RUN/STOP/RESET switch set to "RUN".
OFF: During stop with the RUN/STOP/RESET switch set to "STOP".
