Description
3350-MBP PROSOFT new and original
System Overview
The 3350-MBP Modbus-to-BACnet protocol converter was deployed to bridge communication between legacy field devices and modern SCADA infrastructure at 23 pump stations. Key challenges addressed:
- Legacy Integration: Connected 1980s-era Modbus RTU flowmeters (Daniel 2500 series) to new BACnet/IP BMS (Johnson Controls Metasys)
- Protocol Translation: Achieved 98.7% data fidelity in converting:
Modbus Registers → BACnet Analog Objects (AI/AO) Modbus Coils → BACnet Binary Objects (BI/BO) - Topology: Daisy-chained configuration supported 1.2km RS-485 segments with termination resistors (120Ω ±5%)
Technical Implementation
Hardware Configuration:
| Parameter | Setting |
|---|---|
| Model | 3350-MBP-DFNT (DIN-rail) |
| Baud Rate | 19.2kbps (Modbus), 76.8kbps (BACnet) |
| Power Supply | 24V DC (Class 2) |
| Environmental | -40°C to +70°C (UL Class 1 Div 2) |
Software Setup:
- Used ProSoft Configuration Builder (v6.11) to:
- Map 420 Modbus registers to BACnet objects
- Configure 200ms polling interval
- Enable deadband filtering (0.5% FS)
Operational Results
Performance Metrics (30-day evaluation):
- Latency: 230ms avg. end-to-end signal transmission
- Uptime: 99.998% (MTBF >250,000 hours)
- Diagnostics: Detected and logged 12 ground faults via:
BACnet Event_Notification objects SNMP traps to HMI (Ignition SCADA)
Cost Savings:
- Eliminated $420,000 in PLC upgrades
- Reduced integration engineering hours by 65%
