The maintenance technician uses a laptop computer to see what conditions have to be met in order for the PLC to cause an action to occur (like turn a motor on). Important Note: Just as a doctor asks the patient questions to figure out what is wrong, a maintenance technician asks the PLC questions to troubleshoot the machine.
(His mouth drops open, “… you train brain surgeons?”) That is how I explain it to my doctor any way. The maintenance technicians we train, are the brain surgeons. The PLC is used to control AND to troubleshoot the machine. A PLC (Programmable Logic Controller) is the type of computer that controls most machines today. As this article is not just for the maintenance technician, but for maintenance managers, plant managers and corporate managers. But most importantly, damage to machine and personnel could result from improper maintenance management of your company’s PLCs.įirst I’d like to explain in the most non-technical terms possible, What a PLC is. Thousands to millions could be lost by one little PLC in an electrical panel that you never even knew existed. When the PLC is not functioning properly, lines shut down, plants shutdown, even city bridges and water stations could cease to operate. Why? Because the PLCs (Programmable Logic Controllers) are the brains of your operation. If you could not answer with confidence or you answered ‘No’ to any of the above questions, you need to read this article on maintenance management of PLCs.
Do you have an up to date list of all PLC model types, part availability, program copies, and details for your company?.
How many PLCs is your bottom line depending on?.
