What to do
N/A
1. Reset the controller to restart
the UDP/IP protocol stack and
reset buffer allocations.
2. Contact Honeywell Technical
Assistance if the problem
exists.
Contact Honeywell Technical
Assistance if the status occurs.
1. Check the controller name and
network name of the peer
device to assure that they
match that specific PDE block.
2. Check that the IP addresses of
the peer devices are all within
the range of the IP mask.
3. Check that the peer devices
have the same IP subnet mask.
See Network parameters for IP
mask setting.
1. Reset the controller to restart
the Ethernet IO hardware and
reassign processor IO
mapping.
2. Contact Honeywell Technical
Assistance if the problem
exists.
1. If this status persists during run
time, check that the peer
device is properly connected
and that the control name and
network name is correct.
2. Check that the IP masks of all
peer devices to assure that all
IP addresses are within the
same subnet.
3. Check that all external network
components such as switches
and routers allow passing of
UDP packets on port 502.
4. Check that the peer device is
powered on and is in RUN
mode.
