8.4.2.1 Variable Max_Master

This OPC UA Property, of DataType Byte, represents the BACnet property Max_Master.

The Max_Master value represents the highest possible maximum node address and shall be equal to or less than 127. The default value shall be 127.

8.4.2.2 Variable Max_Info_Frames

This OPC UA Property, of DataType UInteger, represents the BACnet property Max_Info_Frames.

The Max_Info_Frames value represents the maximum number of information frames that may be sent before passing the communications token. The default value shall be 1.

8.4.2.3 Variable Slave_Proxy_Enable

This OPC UA Property, of DataType Boolean, represents the BACnet property Slave_Proxy_Enable.

When the Slave_Proxy_Enable value is true, the device will perform Slave/Proxy functions on the device MS/TP port.

8.4.2.4 Variable Manual_Slave_Address_Binding

This OPC UA Property, of DataType BACnetAddressBinding [], represents the BACnet property Manual_Slave_Address_Binding. The BACnetAddressBinding DataType is defined in 10.5.3.

The Manual_Slave_Address_Binding value represents a collection of manually configured slave devices for which this device is acting as a Slave Proxy.

8.4.2.5 Variable Auto_Slave_Discovery

This OPC UA Property, of DataType Boolean, represents the BACnet property Auto_Slave_Discovery.

When true, the Auto_Slave_Discovery value indicates that the MS/TP master will perform automatic slave detection functions on the master MS/TP port.

8.4.2.6 Variable Slave_Address_Binding

This OPC UA Property, of DataType BACnetAddressBinding [], represents the BACnet property Slave_Address_Binding. The BACnetAddressBinding DataType is defined in 10.5.3.

The Slave_Address_Binding value represents a collection of slave devices for which this device is acting as a Slave Proxy. This set includes the manually configured devices represented by the Master_Slave_Address_Binding and automatically discovered slave devices.The Slave_Address_Binding shall be periodically maintained, but the period at which the list is maintained shall be locally defined.
