Project team
A facility team comparing energy data collection options across panels.
Challenge
The factory needs readings from several panels with different wiring and current ranges. The meters must connect to the existing operations platform.
Equipment in the system
Example equipment arrangement. Check compatibility and agree who handles software, PLC/SCADA programming and site installation.
Data destination
Customer platform or an agreed third-party service
Site context
- Multiple electrical panels
- RS485 meters and CTs under review
- Energy data needed for operations reporting
Approach
- Confirm phase and CT range before meter selection
- Group meters by RS485 bus where practical
- Define gateway output for the customer platform
Hardware plan
- DIN rail or multifunction energy meters
- Split-core CTs
- RS485 gateway
- Optional temperature or cabinet status sensor
Hardware reference

Integration path
- Modbus RTU meter polling
- Modbus TCP or MQTT gateway output
- Data fields aligned with facility reporting
Checks before rollout
- Match each meter to the panel wiring and current range
- Confirm gateway registers and the receiving-system interface
- Test one panel group before repeating the metering configuration
Quote inputs
- Panel layout
- Meter count and phase type
- CT ratio
- Platform protocol and reporting interval

FAQ
How can I use this design example?
Compare the measurement points, equipment connections and site checks with your project. Send the existing devices, available power and receiving system so we can check a suitable configuration.
What should be checked before adding RS485 energy meters?
Check each panel’s wiring, phase count and current range, then select a suitable direct-connected or CT-operated meter. Confirm the supported register map, bus layout and the protocol accepted by the facility’s receiving system.
What should the energy-meter pilot compare?
Compare the local meter values with the gateway and receiving platform, including units, CT ratio where applicable, timestamps and reporting interval. Send the panel layout, meter count, wiring and platform requirements for a configuration quote.
