We are currently executing a major control system modernization, upgrading legacy systems to the latest Siemens automation platform.

Scope of Upgrade:
• Siemens S7-300 PLC ➡️ Siemens S7-1500 PLC
• Siemens OP177B HMI ➡️ Siemens MTP700 HMI

What this upgrade delivers:
✅ Higher processing performance and reliability
✅ Future-ready architecture (TIA Portal integration)
✅ Improved diagnostics and troubleshooting
✅ Enhanced operator interface and usability
✅ Cleaner, more structured panel wiring and layout

From legacy wiring conditions to structured, engineered panels, this is how modernization should be done.

At PLC Systems Technik, Inc. we don’t just upgrade hardware , we re-engineer systems for long-term reliability, maintainability, and scalability.

If you have aging PLC systems (S5 / S7-200 / S7-300 / obsolete HMIs), now is the time to upgrade.

Let’s future-proof your plant.
