Table 8-35: Mapping error messages
Message Suggested corrective action
Assignment of a short address to a device
failed. This could lead to duplicate short
addresses and mapping failures.
1. View the Chain and Device Response Lists
to see
a list of the devices that are present in the
chain
being processed and identify the failed
device.
2. Replace the device.
3. Persistent problem is indicative of a wiring
fault.
Mapping has been disabled. 1. Enable mapping.
While mapping a chain from a device back to
the Signature controller module, the chain
appears to have 2 devices at the same location
in the chain.
1. Indicative of faulty wiring on the circuit, or a
faulty device.
2. Review the Chain and Device Response
lists to identify the conflict.
More than 125 End of Line devices have been
found on the SDC.
1. Correct the wiring.
2. Re-map the circuit.
While mapping a chain from a device back to
the Signature controller module, the chain was
found to have a device present past the end of
the chain. This indicates that at least one
device is responding improperly to the mapping
commands.
1. Click the Device Chains tab to see a list
of the devices that are present in the chain
being processed.
2. Compare the serial numbers or short
addresses
with the actual wiring to identify the
problem.
Mapping has detected a difference between the
device at the end of line and the devices in its
chain.
This indicates that devices not communicating
properly.
1. Click the Communication List tab to see a
list of the devices that are communicating.
2. Compare the serial numbers or short
addresses with the actual wiring, in order to
identify the conflict.
Displaying device chain errors
A chain is a list of devices connected between the Signature
controller module and a device being interrogated during circuit
mapping. The chains and sub-chains created during the mapping
process evolve into the circuit map.
Should a circuit fail to map properly, further insight into the
problem may be gained by investigating the devices making up
individual chains and sub-chains.
