(1) Status LED
(2) Communication Enable Button
Enables the communication mode selected with the communication selector DIP switch. When the communication selec-
tor DIP switch setting is changed while the CPU is powered up, press this button to enable the new communication mode
for the RS485 and RS232C ports.
(3) Communication Selector DIP Switch
Selects the communication mode for the RS485 and RS232C ports, and also selects the device number for the CPU in the
computer link or data link communication network.
Data link mode:
Used for data link communication
User communication mode: Used for user communication or modem communication
Maintenance mode:
Used for computer link communication between the CPU and
WindLDR
on computer
After changing the settings of the communication selector DIP switch while the CPU is powered up, press the communica-
tion enable button for more than 4 seconds until the ERROR LED blinks once; then the new communication mode for the
RS485 or RS232C port takes effect. When the CPU is powered up, the CPU checks the settings of the communication
selector DIP switch and enables the selected communication mode and device number automatically. You have to press the
communication enable button only when you change the DIP switch settings while the CPU is powered up.
Do not power up the CPU while the communication enable button is depressed and do not press the button unless it is nec-
essary.
(4) Memory Card Connector
Plug a miniature memory card into the memory card connector. When a memory card is inserted, the CPU runs the user
program contained in the memory card instead of the user program stored in the CPU memory.
The memory card connector is provided on CPU modules FC3A-CP2KM and FC3A-CP2SM.
(5) Memory Card Eject Button
Press this button to eject the memory card from the CPU module.
(6) RS232C Port 1
Communication port used for the maintenance and user communication modes. User communication instructions TXD1
and RXD1 send and receive data through this port.
(7) RS232C Port 2
Communication port used for the maintenance and user communication modes. User communication instructions TXD2
and RXD2 send and receive data through this port.
POWER
Turns on when power is supplied to the CPU
RUN
Turns on when the CPU is running
ERROR
Turns on or flashes when an error occurs
HSC OUT
Turns on when the high-speed counter comparison output is on
DIP Switch No.
