(3) Notes
When adding a communication station, follow the items below.
Item Reason
Another branch line from a branch line may not give
appropriate communication by reflection wave.
The use of the same station number twice may cause
communication errors.
When the newly added station becomes a termination of
the circuit, change the setting of the LT switch.
Have enough cable length in order to provide easy wiring.
Longer wiring may cause communication error by signal
attenuation.
Maintain the added work data for future maintenance use.
When the communication area or the flag area of the
added station overlaps with other addresses in use,
communication errors may occur.
Without setting the parameter memory of the master
station and that of the slave station, the added station
cannot communicate.
Branch from the trunk cable.
Don’t use the same station number
twice.
Check the termination resistance
switch.
Provide extra length for the
expansion cable.
Do not exceed the 1 km limit for total
length of the cable.
Change the layout drawing for
installation.
Do not overlap with any PC’s
communication area.
Set the parameter memory of the
master station and that of the newly
added station.
No.
