Babel Buster 485 maps LonWorks network variables to Modbus registers Babel Buster 10/100 maps LonWorks network variables to Modbus registers Babel Buster Functional Profile Overview

The Node Object is used to issue requests to all of the sensor and actuator objects, and to check status of those objects.

A maximum send time may be configured for the node status nvoStatus. This results in a network heartbeat for the node.

The Open Loop Sensor Object is used to process the data obtained from a Modbus device. This object maps a single LonWorks network output variable to a single Modbus register.

Send times and send on delta are configurable for each sensor object.

The sensor can be placed in override, in which case the network variable assumes to override value rather than any value that is being produced by Modbus.

The network variable output defaults to SNVT_count_f, but may be changed to any scalar type, or even to SNVT_switch or SNVT_lev_disc.
The Open Loop Actuator Object is used to process data to be sent to a Modbus device. This object maps a single LonWorks network input variable to a single Modbus register.

The input network variable type may be changed to any scalar type.

The actuator may be placed in override by issuing the override request to the object. In addition, the Modbus register will assume a default value (when configured to do so) if LonWorks network updates stop coming.
