7. Precautions for Use of The Equipment
CAUTION
Forbidden
1. Do not switch the network power off while
the network is in communication.
Switching it off will interrupt the
communication of the network as a whole
and set one of the nodes in a busoff state.
Mandatory
1. Do not change node addresses while the S
controller power is on. Otherwise, a node
address setting error will occur. Particularly,
do not change the communication rate
while transmission is under way to a slave
device. To reset, set the DIP switches
correctly, then either issue a reset request
or switch power on again.
Mandatory
1. Prepare programs after fully understanding
the manual.
The sample programs are basic examples
and must be adequately studied for
applicability to an actual system.
viii
Mandatory
1. The DIP switch OSEN must be kept in the
OFF position. When it is set to the ON
position, it may cause trouble or
malfunction.
2. Set the same communication rate for all the
nodes connected to the network. Different
communication rates among the nodes will
result in a slave device error or DN311 error,
disabling communication to restart. To set a
slave device communication rate, read the
pertinent manuals.
3. Do not change the communication rate
while the S controller power is on.
Otherwise, a communication rate setting
error will occur. Particularly, do not change
the communication rate while transmission
is under way to a slave device. To reset, set
the DIP switches correctly, then either issue
a reset request or switch power on again.
