PLC Programming

Keltour is the leader in providing PLC panel solutions, Our staff and technicians have vast knowledge and hands on experience with all the major PLC platforms such as Rockwell Automation, Siemens, Schneider, Modicon, Omron, Wago, Phoenix and more.

Since the inception of PLC’s, Keltour has been designing, building, and integrating numerous types of PLC’s panels from industries of all shapes and sizes. Keltour has built PLC and remote I/O Panels from sizes ranging from single door cabinets to 19 door Enclosures. Keltour has implemented and programmed PLC’s into all the major industrial/commercial applications with our specialty being in plant process automation. Keltour PLC panels are built to strict quality control procedures, testing in place to validate connections, shielding and communication are working properly before the panel leaves our facility.

Keltour uses the most commonly used PLC in process industries. The Top 5 PLC platforms we build and program to are:

  • Rockwell Automation PLC

Learn more about PLC programming services offered by the team at Keltour by reading through our most frequently asked questions for more guidance on our industrial and residential solutions. 


A programmable logic controller (PLC) is a type of specialized, high-powered computer designed for industrial use. In other words, PLC is an industrial computer that oversees inputs and outputs to make decisions according to the program that is stored in the computer’s memory. Using a PLC helps decrease human decision-making requirements, which ultimately increases efficiency. 

There are two different types of PLCs: 

  1. Compact PLC has a specific number of fixed inputs and outputs controlled by the manufacturer.
  2. A modular PLC has multiple inputs and outputs determined by the user’s needs. These can be constructed together on a rack. 

PLCs are also constructed with processors ranging in size depending on program size and the amount of data that needs storage.

The goal of a programmable logic controller (PLC) is to substitute relay-based circuits, enhance the dependability of the structure, and streamline the process of varying processes. 

There are numerous types of programming used in PLCs. Some of the most widely used programming languages include:

  • Ladder diagram (LD) Structured text (ST) 
  • Instruction list (IL) 
  • Sequential function charts (SFC) 
  • Function block diagram (FDB) 

At Keltour, we work with all of the above-noted PLC languages. Therefore, if you require PLC programming services for your business, the team at Keltour can help. Call and speak with one of our representatives or fill out an online form, and someone from our team will get back to you as soon as possible.
