Using Status LEDs
The EC-BOS-6
AX
controller includes several LEDs that can help determine the status of the unit. They are
located in two places: the top of the controller (visible through the cover), and for serial ports, on the bottom
board (only with cover removed). From left-to-right these LEDs include:
•
Ethernet Ports
•
Heartbeat
•
Status
•
Serial Ports
Refer to Figure 2 on page 7 for the exact locations of status LEDs on the EC-BOS-6
AX
controller.
Ethernet Ports
Each Ethernet port (“LAN2”, “LAN1”) has one green LED, visible on the top cover.
A “LAN x ” LED indicates activity on that port as follows:
•
Off —No Ethernet link is made
•
On —Ethernet link is present, but no activity on the LAN
•
Blinking —Ethernet link is present with data activity on the LAN.
Heartbeat
The “BEAT” LED is located to the right of the Ethernet status LEDs, and is yellow. Under normal operation,
this LED should blink about once per second. If the heartbeat LED stays
on constantly , does not light , or blinks
very fast (more than once per second), contact System Engineering for technical support.
Caution
During boot-up, the heartbeat LED blinks in a 90% on - 10% off pattern.
Do not remove power
during this time or data loss may result (I/O module’s firmware upgrade may be in progress.
Status
The “STATUS” LED is located to the right of the heartbeat (“BEAT”) LED, and is green. This LED provides a
CPU machine status check, and should remain lit whenever the EC-BOS-6
AX
is powered. If the STATUS LED
does not light
while power is applied, contact System Engineering for technical support.
Serial Ports
LEDs for the two serial ports are located on the EC-BOS-6
AX
’s
bottom
board, on the
opposite side
of the RS-232
and RS-485 ports (see Figure 2 on page 7). Labels “COM1” and “COM2” correspond to the software
configuration of the COM ports. LEDs show the transmit and receive activity for the serial ports and optional
modem.
Note
You must remove the cover to the serial port LEDs. See “Removing and Replacing the Cover,” page 7.
•
The yellow transmit LED indicates that the EC-BOS-6
AX
is sending data out the serial port over a
communications line to a connected device.
