MultiSmart Installation & Operation Manual
22.2.2 MODBUS Configuration
The entire list of MODBUS points can be accessed and configured by going to:
Multiple Modbus Masters and Modbus Slaves can be configured in MultiSmart. However, consideration
should be given to the number of physical communication ports available and the size of the points list, which
in turn affects the available free memory in the MultiSmart.
22.2.2.1 Add Modbus Slave
A Modbus slave is created by default in the MultiSmart when the default configuration is used or the setup
wizard is being used to generate a standard configuration. Select this option if a new slave is to be added.
This requires a reboot of the MultiSmart.
Once a slave is added, go to the Modbus Slave option to configure the points list.
Then select the Protocol Settings to configure the communication channel.
22.2.2.2 Add Modbus Master
Select this option to create a Modbus Master. When a master is created, a slave profile for that particular
master is also created by default. To add another slave profile under the master, use the Add Modbus
Master Slave option. Multiple masters can be created by selecting this option again. A restart of the
MultiSmart is required for each addition of a master.
Once a master is added, go to the Modbus Master option to configure the points list.
Then select the Protocol Settings to configure the communication channel.
22.2.2.3 Add Modbus Master Slave
A slave profile for the master is created by default when a Modbus Master is created. When more than one
slave is to be configured under that master, select this option. This feature requires a reboot of the
MultiSmart. If multiple masters are configured, the wizard will ask for which master the new slave profile
needs to be created.
