Fewer tools
A large share of field diagnostics in one application.

NODVIA Field
The Swiss Army knife for building automation engineers.
CONNECT·DIAGNOSE·COMMISSION
A mobile Android toolkit for system integrators, service technicians, commissioning engineers and maintenance teams. NODVIA Field combines protocols, network diagnostics, specialised Siemens tools, projects, trends, converters and reports in one practical environment.
PROTOCOL-SPECIFIC TOOLSSpecialised tools, not only generic scanners.
Climatix SCOPE MINI, EM1 Tool, KNX tools, M-Bus, Modbus utilities and other device-focused service tools.
FIELD-FIRST POSITIONING
NODVIA Field is step 1. The wider NODVIA platform is already built and under active testing.
Field is not an isolated app. It is the first public and most practical product in the wider NODVIA concept. When a project grows beyond field diagnostics, the path expands naturally into NODVIA Connect, Core, Logic, View and Edge.
FIELD REALITY
In the field, time to the first useful answer matters.
Is the device on the network? Which address does it use? Is the register correct? What is happening with the object? Did the KNX telegram arrive? What does the Climatix trend history show? NODVIA Field is built around these practical questions.
Instead of opening a different utility for every task, the user follows one mobile workflow: connect first, diagnose second, commission third. When full manufacturer engineering software is required, NODVIA Field does not pretend otherwise—its job is to get the engineer to the correct diagnosis and next step faster.
Less guesswork
Discovery, data and protocol context in one place.
More continuity
Projects, favourites, cache and service context remain organised.
Faster reporting
Export and send results directly from the mobile workflow.
WORKFLOW
Connect. Diagnose. Commission.
Three words describe how NODVIA Field is designed to be used on site.
CONNECT
First determine what is on the network and how to reach it.
- mDNS and LAN discovery
- Deep Scan for devices without mDNS
- BACnet Who-Is
- KNXnet/IP Search
- IP inspection, ping and Wi-Fi analysis
- USB Serial for local serial connections
DIAGNOSE
Once a device is reachable, inspect the data and communication state.
- BACnet objects, properties and trends
- Modbus registers and data formats
- KNX topology, group addresses and telegrams
- Climatix tree, values, schedules and history
- M-Bus data and serial diagnostics
- engineering converters and calculators
COMMISSION
Perform supported service actions and retain a trace of the work.
- supported BACnet/Modbus/KNX writes
- device-specific EM1 and Climatix workflows
- projects, favourites and project cache
- FTP project sharing with the team
- reports and e-mail export
- saved configuration for the next visit
PROTOCOLS & TOOLS
Broad protocol coverage. Device-specific tools where a generic browser is not enough.
NODVIA Field combines standard protocols with concrete service tools. The goal is not just to read a packet, but to present information in a form useful for the actual device.
BACnet Browser
Who-Is, direct device access, objects and properties, favourites, trends, schedules, reading and supported value writing.
View screen →Modbus TCP / RTU
Scanner, Unit ID, register browser, one-based/zero-based addressing, multiple data formats and byte/word order, trends and writing.
View screen →KNX / ETS
ETS project, topology, group addresses, routing/tunnelling, monitor, reading, writing, favourites and additional secure diagnostics.
View screen →Climatix SCOPE MINI
A mobile Climatix service view: object hierarchy, lazy-loaded values, schedules and trend history. The SCOPE tree/cache is isolated by project.
EM1 Tool
Dedicated discovery of EM1 Modbus I/O modules, I/O inspection and supported communication setup without manually guessing register maps.
M-Bus & USB Serial
M-Bus explorer/reader plus USB serial connectivity for meters and RS-485 field devices.
Network Discovery
mDNS, LAN/Deep Scan, BACnet Who-Is, KNXnet/IP Search, IP inspection, ping and Wi-Fi analysis in one discovery layer.
View screen →Local Web Browser
An integrated local web view for devices that expose their own service interface, useful for orientation and full-screen field work.
Engineering Utilities
P/PI/PID explanations and tuning assistance, register/time conversion, three-phase calculations and other small field utilities.
View screen →PROJECTS · TEAM · REPORTS
Field service does not end with the measurement.
NODVIA Field is more than a momentary browser. Projects retain context, can be shared with other team members through an FTP-based workflow, and can produce results for reporting.
Project workspace
The active project separates devices, history and supported cache data. Climatix SCOPE tree/cache is also isolated by project so data does not bleed between sites.
FTP Team Sharing · PRO
Projects can be stored on a configured FTP server and retrieved on another phone, enabling a simple team workflow without requiring a public cloud service.
Reports by e-mail
Supported views and exports can be prepared as reports and sent directly by e-mail/SMTP, shortening the path from field observation to colleague or documentation.
Project workflow, FTP sharing and e-mail reporting.
FREE vs PRO
FREE for inspection. PRO for commissioning and collaboration.
The split is intentionally simple. FREE is for evaluating the app and basic diagnostics; PRO is for users who need writing, specialised tools and an advanced field workflow.
Inspect & Diagnose
- basic device and network discovery
- basic reading of supported BACnet and Modbus data
- basic diagnostic and engineering utilities
- explore the NODVIA Field user and project concept
Commission & Collaborate
- supported value writing and advanced protocol functions
- advanced BACnet, Modbus and KNX tools
- Climatix SCOPE MINI, Siemens EM1 Tool and other specialised tools
- M-Bus, USB Serial and advanced trends/diagnostics
- FTP project sharing and advanced service workflow
- direct reporting and e-mail delivery of supported results
