• Port communication firmware
is not running
• Invalid protocol selected
ARCNET/MSTP
firmware error
• Change rotary switch to
select valid protocol
• Cycle power
Invalid address selected for

ARCNET/MSTP
• Check that network
cable is connected
properly
• Check that baud rate is
correct
Excessive errors detected over 3
second period
Excessive
communication errors
on ARCNET/MSTP
• Check that network
cable is connected
properly
• Check that baud rate is
correct
ARCNET traffic overload possibly
due to circular router or excessive
COVs (change of values)
Event System Error -
FPGA RX FIFO full
• Check the network
configuration for a
circular route
• Increase the time
between COVs to
reduce excessive COV
traffic
All enabled networks are
