Streamline Your Operations with Precision
Systems Integrators for Legacy & Modern Platforms
The Celtex Automation team designs, builds, and commissions complete control systems for Alberta’s industrial sector — from ground-up new installations to complex integrations for legacy equipment of all makes & models.
Seamless Integration
Enhanced Productivity
Legacy System Upgrades
Comprehensive Support
Real Facilities Are Not Clean Slates.
Systems integration in a live industrial environment means working around what’s already there. A new PLC may need to exchange data with a 1990s DCS. A modern servo system may share a machine frame with a relay-logic safety circuit that production can’t afford to take down for rewiring. New SCADA has to talk to field instruments wired for 4–20mA and a Modbus RTU protocol from fifteen years ago.
Celtex brings the breadth to handle that full picture — current platform expertise alongside genuine hands-on experience with legacy hardware, protocols, and wiring conventions. We design systems that work in the real environment, not the ideal one.
Our Core Integration Services
PLC Programming
IEC 61131-3 application development across multiple platforms — ladder, structured text, function block, and instruction list. Full commissioning support from I/O loop checks through production acceptance testing.
Legacy Equipment Support
Ongoing support for control systems that are no longer manufactured — program backup and recovery, spare parts sourcing, fault diagnosis, and engineering workarounds that extend useful life without a full replacement project.
Platform Migration & Retrofitting
Structured migration from obsolete control platforms to modern equivalents — preserving machine behaviour, I/O mappings, and operator familiarity while replacing hardware that can no longer be supported in the field.
We Work Across The Full Equipment Lifecycle.
Legacy Platforms
Keeping Aged Systems Productive.
Discontinued hardware rarely fails at a convenient time. When OEM support is gone and documentation is incomplete, you need an integrator with the technical depth to work from first principles — tracing circuits, recovering programs, and diagnosing faults without relying on a manufacturer’s hotline.

Modern Platforms
Current Systems, Optimized.
New hardware delivers its full value only when it’s specified and commissioned with care. We work across today’s leading control platforms from architecture design through site startup — not just parameter entry and basic I/O checkout.

And much more.
Bridging Yesterday with Tomorrow.
Making Old and New Work Together. Seamlessly.
The most common systems integration challenge isn’t choosing the best new platform — it’s getting that platform to communicate reliably with equipment that predates it by ten or twenty years. Protocol conversion, signal conditioning, data format translation, and network segmentation are practical engineering problems that require hands-on experience with both sides of the connection. Celtex has worked at that boundary enough to know where the friction points are and how to engineer around them without creating fragile dependencies.
Protocol conversion
Bridging legacy serial networks (Modbus RTU, DH+, DF1, DeviceNet) to modern Ethernet-based protocols — including gateway selection, address mapping, and latency management.
Signal & I/O conditioning
Interfacing legacy analog and discrete signals to modern I/O systems — including isolated signal conditioners, relay interface modules, and voltage level translation for mixed-vintage wiring.
Phased migration
Replacing control systems incrementally — running legacy and modern hardware in parallel during transition periods to maintain production continuity.
Systems Integration Projects
Integration Work We Handle
Greenfield Installations
New control systems designed from the ground up — architecture, hardware specification, panel build, programming, and full site commissioning for new equipment or facility expansions.
Brownfield Retrofits
Control system replacement within an operating facility — designed around production constraints, existing field wiring, and the need to minimise planned downtime during cutover.
Machine Re-Controls
Replacement of OEM control systems on specific machines — recovering machine behaviour from observation and I/O tracing where original documentation is incomplete or unavailable.
Network & Data Integration
Connecting isolated control systems to plant-wide networks — SCADA, MES, and historian integration via OPC UA, Modbus TCP, and industrial Ethernet protocols.
Safety System Upgrades
Replacing hardwired relay safety logic with modern safety PLC architectures — risk assessment support, safety function design to IEC 62061 / ISO 13849, and SIL/PL verification.
Remote Monitoring
Adding visibility to previously isolated equipment — instrument loop additions, PLC data capture, and remote HMI access for facilities where on-site presence is costly or infrequent.
Industries Served
Celtex is headquartered in Calgary and serves clients across Alberta and Western Canada. All electrical work is performed under Canadian Electrical Code jurisdiction with direct experience in Alberta’s industrial regulatory environment.
