7-2 VSM500 DeviceNet Option Board
7.2 Understanding the COMM Status Indicator
The COMM status indicator provides status information on the DeviceNet option
board.
Important: When power is first applied to the DeviceNet option board, the COMM
status indicator flashes green for 1/4 second, red for 1/4 second, and then
turns off while the communication module finishes its initialization.
Color State What It Means: What To Do:
None The option board is not receiving
power from the network. Check DeviceNet power and cable
connections and the power
connection on the DeviceNet
terminal block.
Red Solid Diagnostics test failed on
power-up/reset. Internal fault exists. • Cycle power to the VSM500 unit
and network.
• If the fault still exists, return the
option board.
Duplicate DeviceNet node address.
Two nodes cannot have the same
address. • Reset DIP switches 1 through 6
on the DeviceNet option board
using a unique address and then
cycle power.
•
If DIP switches 7 and 8 on the
DeviceNet option board are both
set to ON, change the value of
P103 [
NV MAC ID ] to a unique
address and then cycle power.
Invalid data rate. •
Reset DIP switches 7 and 8 on
the DeviceNet option board to a
valid data rate and the cycle
power.
• If DIP switches 7 and 8 on the
DeviceNet option board are both
set to ON, change the value of
P104 [
NV BAUD RATE ] to a valid
data rate and then cycle power.
Red Flashing I/O connection timed out. Reset the DeviceNet master
device.
Green Solid Normal operating state and device
is allocated to a master. No action required.
Green Flashing Device is online but not allocated to
a master. Verify that the DeviceNet master
has the correct configuration
information for the DeviceNet
option board (node address, input
assembly, and output assembly).
