The problems we solve
If any of these sound familiar, you're in the right place
Most engineers that call Celtex about a Siemens system aren’t calling because everything is fine.
They’re calling because something has gone wrong, something has been wrong for a while, or something is about to go wrong and they’re trying to get ahead of it. Here’s what we deal with most.
Common Siemens issues we see in the field
These aren’t edge cases. They’re the calls we get regularly from facilities running Siemens hardware across Alberta.
Production stopped
Your S7 is in fault and nobody on site can clear it
The CPU is in STOP. The fault buffer shows an error code nobody recognises. Restarting clears the fault but it comes back within the hour. Your maintenance team has exhausted everything they know and production is waiting.
→ Celtex connects online via TIA Portal or STEP 7, reads the fault buffer, traces the logic, and finds the actual cause, not just the symptom. We fix the root problem so the fault doesn’t return.
PROFINET issues
A PROFINET device keeps dropping off the network
An ET 200SP station, a SINAMICS drive, or a third-party PROFINET device is going offline intermittently. It comes back when you cycle power but nobody knows why it’s dropping in the first place. It’s been happening for months.
→ Intermittent PROFINET faults have specific causes. Cable integrity, switch configuration, cycle time conflicts. Celtex diagnoses at the network level using TIA Portal topology view and network diagnostics.
Inherited program
The program runs but nobody understands it well enough to modify it
The integrator who built the system is gone. The program works, but every time someone tries to add an output, modify a sequence, or troubleshoot a fault, they’re working in the dark. There is no documentation, inconsistent naming, logic spread across dozens of FCs with no obvious structure.
→ Celtex audits the program, documents the logic and I/O behaviour, restructures where needed, and delivers a version your maintenance team can confidently work on. With naming conventions and comments that make maintenance easy.
Legacy risk
Your S7-300 is critical to production and you have no clear support path
The S7-300 line is discontinued. CPU and I/O modules are increasingly scarce. Your last program backup might be current (who knows) or it might be three years out of date. You’re not ready to migrate, but you’re aware that an unplanned failure would be a serious problem.
→ Celtex addresses the immediate risk. We pull a current program backup, assess components and build a realistic picture of your exposure without pressuring you into a migration project before you’re ready for one.
Migration complexity
You tried to migrate from STEP 7 to TIA Portal and it didn’t go well
The migration wizard ran, the project compiled, and the system was commissioned, but it doesn’t behave the way the original program did. Indirect addressing is broken, safety functions didn’t translate, or PROFINET device behaviour has changed in ways nobody anticipated.
→ Celtex recovers failed migrations and manages new ones properly. Architecture decisions are made before migration, instruction set differences resolved before commissioning and a phased cutover strategy is provided that protects production throughout.
New installation
You need a Siemens system built right the first time
New machine, new production line, or a control system expansion. You’ve specified Siemens hardware and you need a Calgary-based integrator who will deliver a complete, documented, fully commissioned system. Not one that works well enough at handover and starts generating problems six months later.
→ Celtex delivers complete Siemens PLC programming in Calgary and across Alberta. S7-1200 and S7-1500 systems commissioned to specification, WinCC HMI developed for the operators who will run it. And documentation that holds up long after we leave site.

What you get when you work with Celtex
Siemens PLC programming in Calgary that delivers.
Every Siemens project Celtex delivers includes the same non-negotiables. You get a system that performs to specification, programs your team can work on, and documentation that reflects what was actually installed.
The foundation of every engagement
Structured TIA Portal programs. Built so your team owns them, not us
The most expensive PLC program is the one nobody understands. Inconsistent naming, undocumented logic, and FCs with no clear purpose create a system your maintenance team is afraid to touch. Which means every modification, fault, and expansion requires an outside contractor. Celtex writes Siemens programs in TIA Portal that your team can navigate independently. Consistent tag naming using UDT structures, FC and FB organisation that maps to the physical process, SCL functions with inline comments explaining intent. Not just syntax. Code built for the people who inherit it, not just the person who wrote it.
02
WinCC HMI your operators will trust
An operator interface built around how your process actually runs. Not how TIA Portal’s default template happens to be laid out. Alarm management with cause and corrective action. Recipe handling that reduces changeover errors. Trend displays that make process drift visible before it becomes a quality problem.
03
SINAMICS drives that do what you tell them
SINAMICS drive commissioning via Startdrive, integrated into TIA Portal so the drive, the program, and the HMI work as a single system. STO safety function wiring, and fault handling that gives operators a useful alarm instead of a raw drive fault code to decode under pressure.
04
S7-300/400 support on your timeline, not ours
Your legacy Siemens system is running and you’re not ready to replace it. We'll support it as-is in STEP 7 Classic. Program modifications, fault diagnosis and a current program backup. We’ll tell you when migration makes business sense. We won’t manufacture urgency to sell you a project.
05
PROFINET that stays online
PROFINET network design, device configuration, and fault diagnosis. If your PROFINET devices are dropping intermittently, Celtex finds the cause using topology view and network-level diagnostics. Not by power cycling devices until something comes back online.
06
Safety F-CPU programming that protects your people
S7-1500F safety program development in F-LAD. E-stop, light curtain, and two-hand control functions programmed, tested, and documented to IEC 62061 and ISO 13849. A safety system that was installed to pass an audit and one engineered to protect your workforce are not always the same thing. Celtex builds the latter.
07
Remote access fault resolution without the drive time
TIA Portal supports full online access over a VPN connection. Celtex can provide program monitoring, I/O forcing, fault buffer analysis and program modification without anyone travelling to site. For Alberta facilities outside Calgary, that means a fault diagnosed and a fix deployed in hours rather than a full day lost to travel.
Not sure which of these fits your situation? Describe your system and the problem. We’ll tell you exactly what’s involved and whether we’re the right call.

What STEP 7 to TIA Portal migration actually involves and why it matters
TIA Portal includes a migration wizard. It generates a starting point but not a finished program. Facilities that have gone through “automatic” migrations and found themselves with a system that compiles but doesn’t behave correctly have learned this the hard way. Celtex manages the translation properly.
The migration wizard does some of the work. The rest is engineering.
Understanding what the tool handles versus what requires deliberate engineering decisions is the difference between a migration that succeeds and one that produces a system nobody fully trusts.
What the wizard handles
- Basic block structure import
- Symbol table to tag conversion
- Hardware configuration skeleton
- Network connection mapping
What still requires engineering
- DB structure: optimised vs. standard
- Instruction set differences S7-300 vs S7-1500
- PROFIBUS to PROFINET topology redesign
- Safety program: complete rewrite in F-LAD
- WinCC screen migration and tag reconnection
- Indirect addressing and pointer logic
What Celtex manages
- Pre-migration audit and translation scope
- DB architecture decision before migration
- PROFINET network design and configuration
- Safety F-program rewrite and validation
- Phased cutover to protect production
- Acceptance testing and full documentation
