(4) Input Terminals
These terminals connect input devices such as push buttons and limit switches. DC inputs are both sinks and sources.
(5) Battery Holder
This holder is for installing the backup battery.
(6) Expansion Connector
This connector is used to connect expansion modules.
(7) Input LEDs [IN]
These LEDs turn on when an input is on. The LED with the corresponding number turns on.
(8) Output LEDs [OUT]
These LEDs turn on when an output is on. The LED with the corresponding number turns on.
(9) Power LED [PWR]
This LED turns on when the power is supplied to the CPU module.
(10) Run LED [RUN]
This LED turns on while the CPU module is running the user program.
This LED flashes when using certain functions while the user program is running.
(11) Error LED [ERR]
This LED turns on when an error occurs in the CPU module.
(12) SD Memory Card Status LED [SD]
This LED turns on or flashes when the SD memory card is being read or written.
(13) Battery Status LED [BAT]
This LED turns on or flashes when the remaining voltage in the backup battery is low.
(14) Status LED [STAT]
This LED can be turned on or off in the user program.
(15) Output Terminals
These terminals connect output devices such as electromagnetic switches and solenoid valves. The CPU module is available
in the relay output type (240V AC: 2 A, 30V DC: 2 A), the transistor sink output type (0.5 A), and the transistor protection
source output type (0.5 A).
(16) CAN Port
This port allows J1939 communication.
(17) Ethernet Port 1
This port allows Ethernet communication with connected devices that are equipped with an Ethernet interface.
LED Status
ON • While the CPU module is running the user program
Slow flashing (1 s cycle) • When executing the forced I/O function while the user program is running
Quick flashing (100 ms cycle)
• While the CPU module is in USB boot.
• When executing the forced I/O function while the user program is stopped
LED Status
OFF
• When the SD memory card is not inserted
• When an unsupported or unformatted SD memory card was inserted
• Unmount SD memory card (M8072) is on, so the SD memory card has been unmounted
• When the FC6A Series MICROSmart power is off
ON • The standby state where the SD memory card can be written or read
Slow flashing (1 s cycle)
• When the FC6A Series MICROSmart is recognizing the SD memory card
• Unmount SD memory card (M8072) is turned on and the FC6A Series MICROSmart is unmounting
the SD memory card (slow flashing, then off)
Quick flashing (100 ms cycle) • Reading or writing the SD memory card
LED Condition Battery Status
Off Battery voltage (D8056) > 2,300 Normal Sufficient battery level.
Flashing (1 s cycle) 2,300 ≥ battery voltage (D8056) > 2,000 Warning Low battery level. Replace the battery.
On 2,000 ≥ battery voltage (D8056) Dead battery The battery is almost dead. Or no battery.
