Industrial Control Systems, Inc. (ICS) provides expert PLC programming and upgrade services for manufacturers across the United States. Since 1998, our engineers have programmed and commissioned over 2,500 PLC-based control systems for food processing, packaging, material handling, and heavy industrial applications.
A Programmable Logic Controller (PLC) is the brain of any automated manufacturing system. PLC programming involves writing the logic that controls machines, production lines, and entire facilities. At ICS, our engineers develop custom PLC programs that manage everything from simple motor control to complex multi-line batch processing systems. We write structured, well-documented code that your maintenance team can understand and troubleshoot.
ICS is proficient with all major PLC platforms used in North American manufacturing. Our engineers are certified and experienced with Allen-Bradley (Rockwell Automation) ControlLogix, CompactLogix, MicroLogix, and SLC 500 systems. We also program Siemens S7-1200 and S7-1500 controllers, ABB AC500 and AC800M platforms, Omron NJ/NX and CP series, Mitsubishi MELSEC iQ-R and FX5U, and Opto 22 groov EPIC and SNAP PAC systems. As a Rockwell Automation Silver System Integrator, we have direct factory support and early access to firmware updates and training.
Running obsolete PLCs puts your production at risk. Spare parts become scarce, support ends, and a single controller failure can halt your entire line. ICS specializes in upgrading legacy PLC systems to current platforms with minimal production downtime. We handle the full upgrade process including hardware specification, program conversion, I/O migration, wiring verification, and commissioning. Our engineers convert legacy PLC-5 and SLC 500 programs to modern ControlLogix platforms, preserving your proven logic while gaining modern diagnostics and networking capabilities.
Every PLC project at ICS follows a structured process. We begin with a detailed scope review and I/O listing, then develop the control narrative with your operations team. Our engineers write and simulate the PLC code in-house before arriving on-site, reducing commissioning time by 30-50%. On-site, we install, wire, and commission the system, then train your operators and maintenance staff. After go-live, we provide 24/7 remote and on-site support.
Our PLC programming expertise spans food and beverage processing, pet food manufacturing, building materials, packaging and palletizing, cement and aggregate, chemical processing, water and wastewater treatment, and oil and gas operations. Major clients include Ajinomoto, Mars Petcare, Pillsbury, Church & Dwight, Ash Grove Cement, International Paper, and Schreiber Foods.
ICS is a CSIA-certified systems integrator with 28+ years of experience and 2,500+ completed projects. We are based in Joplin, Missouri and provide rapid on-site response across the United States. Our 24/7 field service support means you are never waiting for help when production is down. We deliver fully documented, maintainable code that your team can support long-term.
