Energy use per line and per piece
Meters and power analysers read over Modbus TCP, joined with the pieces produced and the orders in the ERP: how much energy each line, each shift and each piece takes, with an alarm when consumption looks out of the ordinary.
Illustrative scenario: it describes a typical case, not a customer project.
The energy bill tells you how much you used, not where or for what.
The energy invoice arrives once a month, for the whole plant. Management accounting splits it by estimate, and the production manager cannot tell which line, which shift or which item weighs most.
The meters on the switchboard and the power analysers already measure everything, all the time. Put next to the pieces counted by the PLC and the orders in the ERP, they become consumption per line, per shift and per piece, updated every day.
- Who it's for
- Energy managers, production and plant managers, management accounting.

What you get
- Consumption has an address
- Every kWh is attributed to a line, a shift and an item, not to the plant as a whole.
- Waste shows up straight away
- Draw on a stopped line or an unusual shift triggers an alarm, without waiting for the bill.
- The same figures as management accounting
- Energy per piece starts from the same ERP orders the finance team works with.
- A report that sends itself
- The monthly PDF goes out on schedule with the same charts as the dashboard, with no spreadsheets to rebuild.
For the technical team
How it is built in Muvia
- 1
Read meters and analysers
On the edge node you configure the Modbus TCP driver with each analyser's active energy and power registers, and the S7 driver for the piece counters. The node reads them and sends them to the cloud, with a local buffer if the network drops.
- 2
Compute consumption over the period
The ready-made “Consumption over a period” analysis turns the cumulative counter into kWh per hour, per shift or per day, line by line.
- 3
Bring consumption down to the piece
A query joins each line's kWh with the pieces counted by the PLC and the orders copied from the ERP: energy per piece, per item and per order.
- 4
Compare shifts and periods
With the shift summary and period-over-period comparison you see how consumption changes across shifts, weeks and months, on the same dashboard that runs on the wall screen in the plant.
- 5
Raise alarms and send the report
A threshold with a deadband flags unusual draw, such as a line consuming while its machines are stopped. At month end a notebook becomes a PDF emailed to management.
SQL query
SELECT e.line,
o.item,
sum(e.energy_kwh * p.share) AS kwh,
sum(p.pieces) AS pieces,
round(kwh / pieces, 3) AS kwh_per_piece
FROM hourly_energy AS e
JOIN (SELECT line, hour, order_no, pieces,
pieces / nullIf(sum(pieces) OVER (PARTITION BY line, hour), 0) AS share
FROM hourly_pieces) AS p ON p.line = e.line AND p.hour = e.hour
JOIN erp_orders AS o ON o.order_no = p.order_no
WHERE e.hour >= toStartOfMonth(today())
GROUP BY e.line, o.item
ORDER BY kwh_per_piece DESC- The data it needs
- Energy meters and power analysers read over Modbus TCP
- Line piece counters from a Siemens S7 PLC
- Orders and items from the ERP, copied from SQL Server
- The shift calendar from an Excel file

All use cases- Anomalies and predictive maintenanceVibration, temperature and current read from the PLC become a deviation from normal, a health index and, if you want, a score from a model of your own, in the cloud or on the node next to the machine. When a signal drifts, an alarm goes off and maintenance hears about it.
- The pumping station in 3DPump hall, sump, headers and tanks in the 3D model, every machine carrying its asset's name and its signals alongside. You search for a pump by name, see it in the model and read its vibration against the manual's limits, next to that of its twin.
- From tag names to assetsFive hundred control-system tags, with names such as KP2_P201A_VT01, read by a Python function the way a technician would read them: machine code, instrument, unit. Every match to an asset variable comes with a confidence and a reason, and the doubtful ones go to a person.
