4.9 Setting the RUN Mode
4.9.1 When to Set the RUN Mode
Setting the BM85 to its RUN mode applies the parameters you have
assigned, making the unit ready for operation on the Modbus Plus
network and at its Modbus ports.
When the BM85 is in its RUN mode, it will become active in your
application as soon as power is applied to the unit.
Caution:ąYou must complete the internal configuration of the
BM85 before making the unit active in your application, both
on the Modbus Plus network and at its serial ports.
If you are installing a BM85 that was previously configured for
another application, another network, or a different node, the
unit will still be retaining its previous configuration setup.
You must not connect the unit into the current application and
apply operating power to the unit until you have reconfigured
it for the current application.
4.9.2 How to Set the RUN Mode
Before you set the unit to RUN mode, verify that you have setup its
Modbus port parameters and Modbus Plus node address as described in
this chapter.
Turn off power to the Bridge Multiplexer and set its configuration
switch 8 to the RUN position. Refer to Figure 15 for the configuration
switch location and setting.
If you have set the BM85 configuration correctly for a specific
installation site, you can transport the unit to the site and install it.
The RUN mode will be set when power is reapplied to the BM85.
