Every PLC, HMI, sensor, and drive on a modern plant floor needs to talk to something else, and the network carrying that traffic is one of the least visible but most critical parts of a control system. When it's designed poorly, plants see intermittent faults that are almost impossible to diagnose from the software side alone. Our industrial network design Nairobi clients bring us in for covers everything from new installations to untangling networks that have grown organically, and messily, over years.
Choosing The Right Protocol
Profibus, Profinet, Modbus, and EtherNet/IP each suit different situations, and part of our job is recommending the right one rather than defaulting to whatever a particular vendor pushes. Profinet and EtherNet/IP suit high-speed, data-heavy modern installations; Modbus remains a dependable, simple choice for straightforward point-to-point communication; Profibus is still common on older but well-maintained European-built equipment still running reliably across Kenyan plants.
Physical Layer Design
A large share of the intermittent faults we're called out to diagnose come down to physical layer issues: incorrect cable types, missing termination resistors, poor grounding, or cable runs placed too close to high-voltage lines causing electrical interference. Our industrial network design work always includes a physical layer plan, not just a logical one, because a perfectly configured protocol still fails on badly installed cabling.
Network Segmentation And Security
We design plant networks with proper segmentation between the control network and the wider business IT network, reducing both the risk of a control system fault propagating outward and the risk of an external security issue reaching production equipment. This has become an increasingly common request as more Kenyan plants connect production data to head-office reporting systems.
Troubleshooting Existing Networks
Where a network has grown without a clear design over several years of ad-hoc additions, we map the existing topology, identify weak points, and recommend a phased cleanup rather than requiring a disruptive full rebuild.
Typical Costs (KES)
| Service | Typical Cost Range (KES) |
|---|---|
| Network design and topology planning | 25,000 – 70,000 |
| Physical layer installation review | 12,000 – 30,000 |
| Protocol conversion / gateway setup | 15,000 – 45,000 |
| Network segmentation and security review | 20,000 – 55,000 |
Where We Work
We design and troubleshoot industrial networks for facilities across Nairobi's industrial area, Ruaraka, Athi River, and Thika Road.
Frequently Asked Questions
Can you integrate devices using different protocols on the same network? Yes, we regularly install gateways and protocol converters to bring mixed-protocol equipment onto a single coherent network.
Do you diagnose intermittent network faults on existing installations? Yes, this is one of our most requested services, since these faults are notoriously hard to diagnose without dedicated network diagnostic tools.
Is network segmentation necessary for smaller plants too? Even smaller facilities benefit from basic segmentation between control and office networks, and it's generally inexpensive to implement early.
