Calgary PLC & HMI Programmers
Schneider PLC & HMI
Celtex Electric & Automation are your local Schnider PLC and HMI professionals. We program, install and troubleshoot all models of Schneider PLC from newer Modicon M580 controllers to legacy systems running on the 984 series.
HMI development on Schneider systems running legacy Vijeo software to modern EcoStruxure development projects and everything in between.

Schneider PLC and HMI in Calgary
A Platform With Deep Roots.
Schneider Electric’s Modicon line has a long history in Western Canada’s oil and gas, water treatment, and utilities industries.
Modicon Quantum systems commissioned in the early 2000s are still running production equipment today, sitting alongside newer M580 hardware on the same plant network. The reality of your plant environment is never simple, that is where our team thrives.
We program, install and commission current Modicon and EcoStruxure systems with a level of detail and support that makes maintenance an afterthought. Our team supports legacy Quantum, Premium, and Momentum hardware with the technical experience on hand to diagnose faults and reverse engineer programs when original documentation has been lost.
Your OEM may be costly or unavailable, but production cannot stop. We pride ourselves in rapid response and attention to detail.
SCADA & Data Integration
EcoStruxure SCADA Expert (formerly Citect) integration. OPC UA and Modbus TCP connectivity to third party historian and MES platforms. And multi-vendor plant network system design for Schneider based control systems.
Machine Control
Discrete machine sequencing and motion axis integration via EcoStruxure Machine Expert. Conveyor logic and safety function programming for OEM and custom machine applications on M241, M251, and M262 platforms.
Process Control
PID loop configuration & analog I/O scaling. Valve and pump sequencing, programs and alarm management for continuous process applications in the oil and gas, water treatment, and chemical processing industries on the Modicon M340 and M580.
Redundant Systems
M580 hot standby configuration for high priority process applications. Primary and standby controller setup, switchover testing, and network redundancy configuration for facilities where unplanned downtime is a major consequence of being unprepared.
Utilities & Infrastructure
Water and wastewater SCADA, substation automation and building management integrations. We handle applications where Schneider’s strong presence in the utilities sector means Modicon hardware is the platform of choice both now and in the future.
VFD Integration
Altivar VFD integration over Modbus TCP and EtherNet/IP. Drive parameter configuration, PLC function block development for drive control and monitoring. Plus fault handling programmed within the Modicon software environment.
Schneider PLC & HMI Services
Application Development
New application development and programming across the Modicon PLC platform. Ladder diagram, function block, structured text, and sequential function chart under IEC 61131-3. We are experienced in the Unity Pro, EcoStruxure Control Expert & Machine Expert programming environments.
Legacy Schneider Support
Ongoing support for Modicon Quantum, Premium and Momentum systems still in service. We handle all aspects of automation maintenance from program backup and recovery to fault diagnosis, I/O module cross referencing and Concept / ProWORX program modifications where smooth operation of your legacy equipment is key.
HMI development — Vijeo & EcoStruxure
Vijeo Designer and EcoStruxure application development. From screen layout to tag database configuration, programming alarm management, recipe handling, and trend displays for Schnieder Magelis and Harmony operator HMI stations.
Platform Migrations
Consulting and structured migration plans for those moving from legacy Quantum, Premium, and Momentum controllers to M340, M580, or EcoStruxure Machine Expert. I/O remapping, instruction translation, network architecture updates and HMI cutover managed in detail to minimise production disruptions for your team.

Quantum and Premium — PLC Hardware at End of Life
The Modicon Quantum and Premium product lines are long discontinued and no longer receive OEM support.
Replacement hardware is becoming increasingly difficult to source, Schneider Electric no longer provides software updates, and the Concept and ProWORX programming environments used to develop many of these systems are now significantly outdated.
For the Alberta facilities still running these platforms, that represents a growing operational risk.
Our team understands your environment. Keeping hardware in service that still has life left is often key, and planning migrations carefully on a controlled schedule to avoid shutdown is critical. We keep you ahead of the curve so if a processor fails, your production doesn’t.
Legacy Hardware Support
We pull program backups with all current tooling, diagnose faults, rebuilt prints from scratch and implement engineering workarounds to extend productive life on your Quantum and Premium platforms where replacement is not in the cards.
Migration Planning
When it’s time to replace your hardware, our team designs a structured migration scope assessment, audits I/O and performs a thorough of the software transition from Concept to Control Expert. All this translates to a clear budget for your capital projects.
Cutover Execution
We carefully manage the cutover to M340, M580, or EcoStruxure Machine Expert from your outdated hardware. Our team can implement parallel run strategies to guarantee production and post cutover runtime support.
Maximize Your Potential
Celtex is based in Calgary and serves clients across Alberta and Western Canada. All electrical work is performed under Canadian Electrical Code jurisdiction with direct experience implementing new Modicon M340, M580 and Schneider HMI projects in facilities like yours across Southern Alberta.
How we Approach a Schneider Electric Project
Program & System Audit
For existing systems we begin by understanding what’s there. Reviewing existing programs, I/O configurations, network topology, and any available documentation before recommending changes or additions. Modifying a live system without full understanding is a common cause of production upsets.
Structured Program Development
New Modicon programs are developed in Control Expert or Machine Expert against a defined I/O list and functional specification from you. All programming is completed with consistent naming conventions, derived function blocks for repeating logic, and comments that explain the process intent & function, not just the instructions. Code written with your maintenance team in mind for ease of future support.
Network & I/O Commissioning
Modbus TCP and EtherNet/IP device configuration, I/O module setup, and QA/QC loops verification is always completes before equipment is energised. Modicon network configuration, particularly on older Modbus Plus infrastructure has specific diagnostic requirements that differ from EtherNet/IP-based platforms. We keep every detail in mind to make your life easy.
Functional Testing & Acceptance
Systematic functional testing against the design specifications with operations staff present for your intial production run. When installing redundant M580 systems, switchover testing and recovery time verification are included in the acceptance package prior to handover.
Documentation & Handover
Program backups in current Control Expert or Machine Expert format are always provided. Redlined drawings and as-built I/O lists, a network topology diagram, and a maintenance handover package written for the team who will be responsible for the system after commissioning is complete.
