Eupry Smart Instruments · For pharma manufacturing

Calibration in seconds for the FMS you already have

A non-disruptive upgrade of your facility monitoring. Keep your cabling, PLC, SCADA, and historian. Instruments arrive pre-calibrated and traceable, and the point goes back in service in seconds instead of waiting out a calibration window.

Calibration becomes a property of the instrument

Every step that forms the measured value happens inside the instrument. The calibration travels with it, which means it can be done before the instrument reaches your site.

  • Calibrated

    ISO/IEC 17025 accredited calibration in our laboratory. Every instrument ships with its as-left certificate.

  • Exchanged

    Service mode, swap, check the reading, back in service. No loop isolation.

  • Traced

    The serial number travels with every measurement, and the certificate is tied to the same number.

  • Returned

    Send the removed instrument back for as-found calibration, as an optional service.

Choose the connection that matches each area

No rewiring needed. Each area can connect through the cable already in the wall, or over Ethernet where you have it.

Existing 4-wire cable

Modbus RTU over RS-485 on the cable already in the wall. Same terminals, same 24 V feed, one communication module per point.

Ethernet

For new builds and areas with OT networking to the field. OPC UA and MQTT Sparkplug B recover buffered data natively.

Existing 2-wire cable

Power and data on one pair for legacy loop-powered points. Talk to us if this is what your site has.

Which PLC platforms are supported

Siemens S7-1500 is the reference design, using the CM PtP RS422/485 module and the Modbus master function block from the TIA Portal library, which carries no licence cost. S7-1200 is validated on the bench.

Rockwell ControlLogix and CompactLogix, ABB AC500, and Emerson DeltaV follow the same pattern, and we confirm the interface module and library for your platform during scoping.

Calibrate the instrument, and the chain is calibrated

A Eupry Smart Instrument sends a finished value in engineering units, protected by a CRC-16 checksum. Your PLC, SCADA, and historian only carry and store it, so the calibration boundary sits at the instrument.

That holds as long as the PLC applies no re-scaling and the firmware stays under Eupry change control. Both are verified during OQ.

Validate once, not every instrument

Qualify the installation once, under your change control. After that, each like-for-like instrument exchange runs under a pre-approved SOP, with no further change control.

Start with one panel

  • Scoping

    Point list, cable types, PLC platforms, and the target protocol per area, agreed with your OT and QA teams. We build the business case from your point count, your calibration intervals, your hours per point, and the cost of a production window. We do not quote a saving without your numbers.

  • Bench validation

    End-to-end link on a lab PLC with the chosen module and function block.

  • Pilot point

    One production panel, running next to an existing 4–20 mA point.

  • Qualification

    IQ and OQ using the validation package.

  • Roll-out

    Area by area, with exchanges running under the routine SOP.

Frequently asked questions

FAQ

Does the PLC need to do any scaling?

No, and it must not. The instrument delivers values in engineering units. If the PLC or SCADA applies a conversion, that calculation becomes part of the measuring chain and has to be verified during OQ.

What happens to the data during an exchange?

The point goes into service mode first, exactly as it does for in-situ calibration today. Alarms are suppressed by design and the data is flagged. Communication loss during the exchange is expected and is not raised as a process alarm.

What if the PLC restarts or the link drops?

Each instrument buffers its own measurements locally. On polled protocols such as Modbus, the function block reads back buffered samples by timestamp and sequence number until the historian is up to date. On OPC UA and MQTT Sparkplug B, the historian or broker recovers the data natively.

How do we know which certificate belongs to which measurement?

The instrument sends its serial number with its measurements. Record that as a historian tag, logged on change, and a join on timestamp shows which instrument, and therefore which certificate, produced every value.

What happens if an as-found calibration comes back out of tolerance?

We provide the full as-found data, and the impact assessment follows your own deviation procedure. As-found calibration is an optional service, and whether you need it is a QA decision.

Does anything connect from our OT network to Eupry?

No. No Eupry server is installed on site and there is no OT-to-cloud connection. Certificates are retrieved on the enterprise IT side, over outbound HTTPS from your CMMS.

Can firmware be updated remotely?

Over-the-air updates can be disabled, or the OT variant can be supplied without update capability. Firmware is refreshed through the regular instrument exchange instead.

Who does the PLC and SCADA work?

Usually your automation team or your system integrator. We supply the function blocks, the register map, reference wiring, and the IQ/OQ test scripts.

Do we have to buy the instruments?

Instruments are delivered as a service and exchanged per agreement, typically yearly, so the hardware and firmware stay current over the life of the facility without a separate spare-parts programme.
