Unit Components and Specifications
SECTION 2
2. Input indicators (yellow)
The input indicators are lit when the corresponding input terminal is ON. The
status of an input indicator will reflect the status of the input even when that
input is being used for a high-speed counter.
Note a) When interrupt inputs are used in interrupt input mode, the indicator
may not light even when the interrupt condition is met if the input is
not ON long enough.
b) Input indicators will reflect the status of the corresponding inputs
even when the PLC is stopped, but the corresponding input bits will
not be refreshed.
3. Output indicators (yellow)
The output indicators are lit when the corresponding output terminal is ON.
The indicators are lit during I/O refreshing. The status of an output indicator
will also reflect the status of the corresponding output when the output is be-
ing used as a pulse output.
4. PLC status indicators
The following indicators show the operating status of the PLC.
Indicator Status Meaning
ON Power is being supplied to the unit PWR
(green)
OFF Power isn’t being supplied to the unit
ON The PLC is operating in RUN or MONITOR
mode RUN
(green)
OFF The PLC is in PROGRAM mode or a fatal
error has occurred.
ON A fatal error has occurred. (PLC operation
stops.)
Flashing A non-fatal error has occurred. (PLC
operation continues.)
ERR/ALM
(red)
OFF Indicates normal operation.
Flashing Data is being transferred via the peripheral or
RS-422/485 port. COMM1
(yellow)
OFF Data isn’t being transferred via communica-
tions port.
Flashing Data is being transferred via the RS-232C port COMM2
(yellow)
OFF Data isn’t being transferred via communica-
tions port.
5. Communications port
Connects the PLC to a Programming Device (including Programming Con-
soles), host computer, or standard external device. Use a proper Connecting
Cable (CPM2C-CN111, CS1W-CN114, CS1W-CN118, or CS1W-CN226).
Note a) A CQM1H-PRO01-E Programming Console can be connected di-
rectly to the PLC.
b) A C200H-PRO27-E Programming Console can be connected di-
rectly to the PLC with a CS1W-CN224/CN624 Connecting Cable.
c) Use a CPM2C-CN111 or CS1W-CN114 Connecting Cable to con-
nect to the communications port as a peripheral port. The communi-
cations port can be used simultaneously as both a peripheral port
and RS-232C port by using the CPM2C-CN111 Connecting Cable.
d) Use a CPM2C-CN111, CS1W-CN118 or CS1W-CN226 Connecting
Cable to connect to the communications port as a RS-232C port.
