4. Summary Th section will help to give a basic overview and quick summary of the procedures needed to install the P1 Gateway Panel Detailed instructions are also provided later in this guide The Centaurus Prime P1 Gateway allows any front end system Modbus Master or BACnet IP that communicates using the either industry standard Modbus or BACnet protocols to communicate to Siemens also known as Staefa Landis amp Staefa Landis amp Gyr Powers or even MCC Mark Controls for real old timers P1 trunk field equipment The P1 trunk field devices supported MPU DPU and TEC devices will appear to the front end system as a series of Modbus SLAVE devices or BACnet Devices Real time point data from the Siemens P1 trunk controllers is then mapped to equivalent registers coils and bits on the Modbus system or as AL BI AO and BO objects on the BACnet system All operations are transparent to the user and host computet ICON REN Connections to the P1 Gateway are simple and clearly marked They consist of 7 Valuable information poser Supply 120 Volts AC optionally 220 or 240 Volts AC e Siemens P1 trunks up to four these are RS 485 multi drop trunks e Modbus RTU Network RS 485 or IP or BACnet IP Network Local Mode Port for commissioning via Laptop Computer All Hardware necessary to connect the Gateway to the P1 devices is included in the 16 X 14 X 8 plastic cabinet that is easily mounted in a convenient
