Modernise with Confidence
Reducing Risk and Avoiding Downtime
Ageing control systems don’t just slow you down — they expose your operation to security vulnerabilities, unplanned downtime, and rising maintenance costs. Modernisation is the path forward.
Why Act Now?
Legacy OT systems were never designed with connectivity in mind. As IT/OT networks converge, unpatched equipment becomes an open door for attackers targeting critical infrastructure.
Higher OEE & Throughput
Modern drives, controllers, and sensors reduce cycle times, cut unplanned stoppages, and give you the data to push OEE beyond what legacy hardware allows.
Variable-speed drives and intelligent motor management can cut energy consumption significantly — turning modernisation into a measurable cost saving, not just a capital expense.
Real-time data from modern automation platforms feeds dashboards, predictive maintenance tools, and MES systems — giving you visibility that older equipment simply cannot provide.
The greatest risk isn't the cost of upgrading — it's the cost of not upgrading.
A well-executed modernisation programme, planned around your production schedule, delivers far less disruption than an unexpected failure of an obsolete component.
PG's Structured Approach to Modernisation
Every modernisation project is different. Whether you’re upgrading a single drive line or migrating an entire plant, our approach scales to fit your operation.
1. Lifecycle & Risk Assessmet
We begin by auditing your installed base — identifying end-of-life components, spare part availability, and the criticality of each asset. This gives you a clear picture of where risk is concentrated.
2. Strategy: Phased or Full Migration
Not every plant can shut down for a full cutover. We define a migration strategy that matches your operational reality — whether that’s a rolling phased upgrade or a planned full replacement during a scheduled outage.
3. Detailed Engineering & Simulation
Before anything is touched on the floor, we model the new configuration — validating performance, sequencing, and interlocks in simulation to reduce surprises during commissioning.
4. Controlled Implementation & Commissioning
Changeovers are executed to a tightly managed programme, with rollback plans in place. Each stage is signed off before the next begins — keeping your team in control at every step.
5. Training & Post-Implementation Support
New technology only delivers value when your team is confident using it. We provide hands-on training and structured post-implementation support to ensure a smooth transition.
DIY Approach: Supported by PG
You may be in a position to handle modernisation in house but could benefit from the extra support available. PG offers hands on workshops, pre and post-sale support, also access to free tools and guides to help your modernisation project meet its potential.
1. Free Tools & Guides
Access our full library of migration tools, compatibility checkers, and technical guides to support your planning and engineering work at every stage.
2. Workshops & Training
Our practical workshops are designed to build your team’s confidence with new platforms and tools.
3. Pre & Post-Sale Support
Whether you’re still scoping the project or already in implementation, our team is available throughout. Pre-sale, we help you specify correctly. Post-sale, we make sure everything lands as planned.

A Changing Regulatory Landscape
Cybersecurity regulation is no longer confined to IT. Both NIS2 and the Cyber Resilience Act directly affect OT environments — and legacy equipment is increasingly difficult to bring into compliance.
NIS2
CRA
NIS2 & CRA
The EU’s Network and Information Security Directive (NIS2) extends mandatory cybersecurity obligations to operators of essential services — including manufacturing, energy, and transport. Non-compliance carries significant financial penalties.
- Risk management obligations for OT systems
- Incident reporting within 24 hours
- Supply chain security requirements
- Board-level accountability
The Cyber Resilience Act introduces mandatory cybersecurity requirements for products with digital elements sold in the EU. Connected automation equipment must meet security-by-design standards throughout its lifecycle.
- Security requirements from design through EOL
- Vulnerability disclosure obligations
- Security update guarantees required
- Applies to hardware and embedded software
The Hidden Risks of Grey Market Purchases
When genuine spares are scarce, the temptation to source from unofficial channels is understandable. The risks, however, are rarely visible until it’s too late. Protect yourself from hidden risks by always purchasing from an authorised distributor.
RISK
No Warranty
Grey market parts carry no manufacturer warranty. Any failure leaves you with no recourse — and a production line that’s down.
RISK
Increased Failures
Counterfeit or improperly stored components fail faster, often at the worst possible moment. Without traceability, root cause analysis becomes guesswork.
RISK
Hidden Cyber Risks
Unofficial hardware may contain modified firmware. A compromised component on your OT network can give attackers a persistent foothold — completely invisible to your security tools.
