From Wastewater Equipment to Connected Equipment: A Smarter Edge I/O Approach

From Wastewater Equipment to Connected Equipment: A Smarter Edge I/O Approach

For many small and mid-sized Maschinenbau and Anlagenbau companies in Germany, industrial wastewater treatment equipment is becoming more connected.

A typical treatment skid may include pumps, valves, flow meters, pressure sensors, level sensors, pH/temperature transmitters, VFDs and other field devices — while customers increasingly expect remote monitoring, data logging and cloud connectivity.

The challenge?

The more I/O and communication requirements a machine has, the more complex the traditional architecture becomes:

PLC + I/O modules + communication gateway + cloud gateway + remote access

For equipment manufacturers building standardized machines, this can mean more hardware, more wiring, more engineering and more maintenance.

What if the edge controller could handle all of this in one device?

This is where BLIIOT BL192Pro IIoT EdgeIO Controller can bring a different approach.

BL192Pro combines I/O acquisition, protocol conversion, local logic control, cloud connectivity and remote maintenance in one compact edge controller. It provides 1–3 flexible I/O expansion slots, allowing manufacturers to select the I/O combination according to the actual requirements of each wastewater treatment system.

Flexible I/O for real wastewater applications

A wastewater treatment machine rarely has the same I/O requirements from one project to another.

One system may need more digital signals for pumps and valves.

Another may require multiple analog channels for:

• Flow
• Pressure
• Level
• pH / process sensors
• Temperature

BL192Pro can be configured with different I/O modules, including:

DI / DO · Relay · 4–20 mA / 0–10 V AI/AO · PT100/PT1000 · Thermocouple · RS485/RS232 · Pulse I/O

The controller supports up to 3 I/O expansion boards, making the hardware architecture adaptable instead of forcing every machine into the same fixed I/O configuration.

From field data to the cloud — without an additional gateway

This is where BL192Pro becomes more than a conventional remote I/O module.

It provides two Ethernet ports, built-in RS485, and supports MQTT, Modbus TCP and OPC UA.

That means field data can be collected at the machine level, processed locally and then transferred directly to higher-level systems or IoT platforms.

For example:

Local Logic & Data Processing

MQTT → Cloud Platform
OPC UA → SCADA / MES
Modbus TCP → PLC / Automation System

No separate cloud gateway is required.

A practical example: Industrial Wastewater Treatment Skid

Imagine a compact wastewater treatment system manufactured by a German Anlagenbau company.

The BL192Pro can collect:

DI: Pump running/fault status, valve feedback, alarm signals
AI: Flow, pressure, level and process measurements
RTD/TC: Temperature monitoring
RS485: Modbus instruments, meters or other field devices

At the edge, simple control logic can be configured through the built-in web server.

For example:

High-level alarm → Pump protection logic

Abnormal pressure → Equipment alarm

Scheduled condition → Automatic control action

The same data can then be published to the customer's cloud platform through MQTT, while OPC UA can provide standardized data access for SCADA or MES integration.

BL192Pro also supports BLRAT remote access for remote firmware upgrades and parameter configuration, helping equipment manufacturers reduce unnecessary on-site service visits.

Why this matters for equipment manufacturers

For a large automation project, adding another gateway may not be a major issue.

For a small or mid-sized equipment manufacturer building dozens of similar machines, however, every additional component affects the BOM, wiring, engineering time and service workload.

BL192Pro offers a more integrated architecture:

Flexible I/O
→ Adapt the hardware to each machine

Local Edge Logic
→ Handle simple control and calculations locally

Multi-Protocol Connectivity
→ Modbus TCP + OPC UA + MQTT

Direct IoT Connectivity
→ Send machine data to cloud platforms

Remote Maintenance
→ Reduce unnecessary service visits

Compact DIN-Rail Design
→ Easy integration into control cabinets

The result is not simply “another I/O module”.

It is an Edge I/O platform for building connected industrial equipment.

The bigger opportunity

For German Maschinenbau and Anlagenbau companies, the next step in wastewater equipment may not be replacing the existing PLC architecture completely.

It may be about adding intelligence at the edge.

Instead of:

PLC → I/O → Gateway → Cloud

consider:

Field Devices → BL192Pro → PLC / SCADA / MES / Cloud

One flexible EdgeIO controller can bridge the gap between field-level signals and industrial IoT, while giving equipment manufacturers more freedom to standardize their machine architecture.

Build the machine once.
Connect it everywhere.
Maintain it remotely.
