Communication & Integration

Communication & Integration: One Language Across Your Factory

Most factories do not lack data. They lack a reliable way to move it between the systems and people who need it. Sensors report to one platform, PLCs to another, and the ERP knows about none of it until someone enters the numbers manually. INGSOL’s Communication & Integration work closes that gap, connecting operational technology (OT) on the shopfloor with information technology (IT) at the business level, so that machines, systems and people are working from the same information, in real time. This page sets out what that involves and how INGSOL delivers it for factories and manufacturing plants across industries.

Why OT-IT Integration Is Difficult in Practice

Most plants accumulate systems in layers, over years, rather than by design. A PLC installed a decade ago, a SCADA system added later, and an ERP implemented separately at the corporate level rarely share a common protocol or data model. Left alone, this produces a familiar set of problems:

Disconnected systems: data sits in isolated systems that were never designed to exchange information with each other.
Vendor lock-in: proprietary interfaces tie a plant to a single supplier, making it costly to add new equipment or switch vendors later.
Legacy equipment left behind: legacy PLCs and instruments, still mechanically sound, are excluded from digital initiatives because they cannot communicate on modern networks.
Manual data entry: ERP systems plan production based on assumptions, because shopfloor execution data does not flow back automatically.

INGSOL’s approach is to design communication and integration deliberately, using open standards, so that these problems are addressed at the architecture level rather than patched over with one-off interfaces.

Open Protocols: A Common Language for Industrial Data

The starting point for reliable integration is agreeing on how systems talk to each other. INGSOL builds on established, vendor-neutral industrial protocols so that equipment from different manufacturers and different eras can exchange data without custom, fragile connections.

OPC UA and MQTT

OPC UA and MQTT are the two protocols INGSOL relies on most for open, real-time data exchange. OPC UA provides a secure, structured way for industrial systems to share process data and metadata, while MQTT offers a lightweight publish-subscribe model well suited to high volumes of sensor data moving between edge devices and cloud platforms. Together, they allow devices, SCADA systems and analytics platforms to communicate without being locked to a single vendor’s proprietary format.

Modbus, EtherNet/IP and PROFINET

Alongside OPC UA and MQTT, INGSOL supports Modbus TCP/IP, EtherNet/IP and PROFINET, the protocols most commonly found on existing PLCs, drives and field instruments. Supporting this wider set of protocols means legacy equipment can be integrated into a modern architecture without replacement, rather than being left disconnected.

Industrial Networking Built for the Shopfloor

Office-grade networking equipment is not designed for the vibration, temperature swings, electrical noise and dust found on a typical production floor. INGSOL designs wired and wireless industrial networks specifically for these conditions, prioritising interference resistance, physical durability and consistent throughput. Where distance or cabling is impractical, we deploy wireless connectivity, including LoRaWAN for remote or distributed sensors, alongside conventional industrial Wi-Fi and Ethernet, so that network design matches the physical realities of your site rather than a generic template.

From SCADA to IIoT: Extending What You Already Have

Many factories already operate a functioning SCADA system for supervisory control. Rather than replacing it, INGSOL typically extends existing SCADA with IIoT capability: secure cloud connectivity for enterprise-level visibility, remote and mobile access for supervisors and managers away from the control room, and analytics that support predictive maintenance rather than only historical reporting. This gives plants broader visibility and flexibility while preserving the investment already made in existing control systems.

How INGSOL Delivers Communication & Integration

Unified IT-OT Architecture

Machines, control systems, IT infrastructure, and cloud platforms are brought together into one coherent architecture, giving end-to-end visibility of data rather than a collection of separate silos.

Protocol coverage across your equipment

Machines, control systems, IT infrastructure, and cloud platforms are brought together into one coherent architecture, giving end-to-end visibility of data rather than a collection of separate silos.

Reliable network design

Industrial-grade wired and wireless networks are engineered for uptime, efficient bandwidth use, and secure communication, matched to your site’s physical conditions.

Edge and cloud working together

Local edge processing handles time-critical decisions, while cloud platforms support enterprise dashboards and cross-site analytics, each doing the job it is best suited to.

Built to scale

Integration architecture is designed to accommodate new lines, sensors, sites, and technology upgrades without requiring a redesign.

Why Manufacturers Choose INGSOL for Communication & Integration

No vendor lock-in: every solution is built on open, vendor-neutral protocols, so your factory retains the freedom to choose equipment and suppliers on merit.
Works with what you already have: legacy PLCs, drives and instruments are integrated through protocol support and retrofitting, not replaced by default.
Security by design: network segmentation and access control are designed into the architecture from the outset, not added as an afterthought.
Tailored to your infrastructure: integration work is scoped around your specific equipment, protocols and site conditions, rather than a standard package applied uniformly.
Part of a complete digital transformation capability: Communication & Integration is delivered alongside INGSOL’s wider Digital Transformation, Industrial Solutions, Energy and INGSOL Labs verticals, giving you one accountable partner rather than multiple disconnected vendors.
