Troubleshooting
Note: 1 If you cycle the power supply to the E5@C-T Controllers after the error occurs, perform procedure “a”
given above.
2 If you cannot solve the problem with the above flowchart or if the situation becomes too confusing, cycle
the power supply to all of the E5@C-T Controllers and then perform procedure “a” given above to copy the
parameter settings to all of the slaves.
Check the slave where the error occurred.
YES
NO
NO
NO
copy displayed?
Execute the copy again from the master using all.
Is the wiring incorrect?
YES
NO
YES
YES
YES
Copying is not possible. Copy the parameter
settings to the remaining slaves by specifying
their communications unit numbers individually.
Is the model number of the slave different
from the master?
Turn OFF the power supply and correct the wiring.
a) If there are a lot of slaves to which the settings
were not copied, set the Protocol Setting
parameter to cwf and the Communications
Baud Rate parameter to 9.6, return to the
operation level. Set the communications baud
rate of the master to 9.6, return to the operation
level, and then execute the copy again using
all.
b) If there are only a few slaves to which the
settings were not copied, copy the parameter
settings to the remaining slaves (i.e., those for
which copy is not displayed) by specifying their
communications unit numbers individually.
Is the Protocol Setting parameter set to something
other than cwf?
Are the communications unit numbers incorrect?
Is the communications baud rate set to something other than 9.6?
The communications unit number of the
slave where the error occurred is also
being used by a downstream slave.
Correct the set values, return to the operation
level, and then execute the copy again from the
master using all.
