Product · Connectors

It speaks the protocols your network already speaks.

Connectors are the building blocks of a Meddle flow. Each one reads from a source, writes to a destination, or transforms data in transit. No gateway to buy, no proprietary format.

The three families

Read, write, transform.

Industrial

Twelve types towards automation and PLCs: OPC-UA, Siemens S7, Modbus TCP and RTU, Logix, CoAP. Any brand, including machines fifteen or twenty years old.

IoT and databases

Twelve types towards IoT protocols and storage: MQTT, HTTP, InfluxDB, MongoDB, SQL, Redis, Firebase. Machine data lands where you already read it.

Processing

Twenty types that work on data in transit: filters, merge, reshape, triggers, cron. The transformation lives in the flow, not in a script on the side.

Protocols

Industrial standards, no proprietary adapters.

Plus Redis and Firebase on the storage side, and the canvas processing connectors. If a connector is missing we build it as part of the suite, with no upsell.

How it connects

Configure once, then the flow runs itself.

Configure

Address, credentials and the tags to read. We run the first session together with your IT or OT contact.

Normalise

Every connector returns the same key-value JSON format, so sources become comparable.

Route

The same reading goes to several destinations at once: history, database, alerts, ERP or MES.

Frequently asked questions

The rest, in short.

Do I need extra hardware?

For most PLCs, no: connectivity is software. Where a measurement is missing entirely we add an instrument, only where it is genuinely needed.

Does it work with PLCs from different brands?

Yes. OPC-UA, Siemens S7, Modbus, Logix and MQTT cover mixed machine parks. Any brand, no lock-in.

What if the connector I need does not exist?

We build it as part of the suite, at no extra cost. Connectors are the piece we maintain for you.

Do I have to open ports into the OT network?

No. The field agent opens outbound connections, compatible with DMZ and segmentation.
