The gateway data base consists of 250 Modbus registers, each configured with a target BACnet
object’s data:
1. BACnet device address where the object resides (MS/TP Node address / MAC)
2. Object type (BI, BV, BO, AI, AV, AO, MI, MV, MO)
3. Object Instance (object number)
Separately the BACnet network baud rate and Maximum Master value must be set. The gtaeway is
generally set as being Device Instance 0.
