Programmable Logic Controllers

Programmable Logic Controllers are a valuable tool for the automation of electromechanical processes. Our industrial electricians work on Programmable Logic Control (PLC) centers to ensure effective process automation for a range of businesses.

Whether you need a new PLC system designed, an existing system upgraded, or ongoing maintenance and troubleshooting, Southern Electrical Services has the expertise to keep your automation running at peak performance.

PLC Services

Our industrial contractors design and build automation controls for new processes, machinery and system modifications. In addition, we also install, configure and program PLC equipment to enable integration and communication with other systems and equipment controllers.

Our contractors work on conveyor control systems, batching systems, generating stations and control panels. We also perform upgrades and retrofits for older PLC systems, modernizing your automation infrastructure without disrupting production.

PLC Functionality & Expertise

Our expert industrial contractors understand the complete functionality of Programmable Logic Controls. Our technicians are experts in process control, motion control, sequential relay control, distributed control systems, as well as networking.

Our electricians program controllers in a variety of ways, such as relay-derived ladder logic and various programming languages — ensuring your PLC system is optimized for your specific process requirements.

FAQ

Frequently Asked Questions

What PLC platforms does your team support?
Allen-Bradley (Rockwell ControlLogix, CompactLogix, MicroLogix, SLC, PLC-5), Siemens (S7-1200/1500, S7-300/400), Mitsubishi, Modicon, GE, and others. We also work with HMI/SCADA platforms including FactoryTalk View, WinCC, Wonderware, Ignition, and Citect.

Can you upgrade or migrate a legacy PLC system without taking the plant down?
Often, yes. Common patterns: stage the new PLC + I/O alongside the old one, parallel-test, then cut over during a planned outage or shift change. For SLC-to-CompactLogix migrations we can typically reuse rack space and most field wiring. The right approach depends on the platform, network topology, and your tolerance for downtime — we scope and plan it with your operations team.

Do you do PLC programming, or only installation?
Both. Our team writes ladder logic, function block, and structured text for new processes and modifications. We also troubleshoot existing code, recover programs from un-documented PLCs, and document logic for sites where the original integrator is gone.

Can you build custom control panels?
Yes — UL 508A-style industrial control panel design and fabrication, including PLC enclosures, MCC bucket modifications, VFD panels, instrumentation panels, and operator interface stations. All built to the NEC and your facility's electrical standards.

What about VFDs and motor control integration?
We integrate variable frequency drives (Allen-Bradley PowerFlex, Siemens Sinamics, Yaskawa, ABB, etc.) with the PLC over EtherNet/IP, ProfiNet, Modbus TCP, or hardwired. Includes drive parameter setup, motor data, regen/braking, network configuration, and HMI integration.

Do you offer 24/7 emergency PLC troubleshooting?
Yes — when a PLC fault stops production, call (713) 660-7344 any hour. Our industrial electricians can troubleshoot remotely (if VPN access is available) or on-site, and we keep common spare modules in stock to minimize downtime.
