PLC stands for programmable logic controller and is a specialized computer system that controls aspects of industrial manufacturing operations, such as automated processes. As a remote PLC programmer, you work from home to write code and create software for these purposes, as well as provide technical support for customers and companies that use this software. In addition to your programming responsibilities, you work on existing PLC systems to create more efficient processes and troubleshoot when the system has an issue. Other duties include documenting your work and training other employees on how to use the software in a manufacturing environment.
