BACnet Object Properties supported by Babel Buster BB2-7010

The mappings shown on this page are used when the BB2-7010 is treated as a Modbus RTU Slave. All objects are accessed as holding registers. These mappings are also used when the BB2-7010 is treated as a Modbus TCP Server (slave). The local register numbers may be accessed as holding registers. In addition, if the Modicon mapping option is turned on (TCP only), binary points can be accessed as coils.
