Description
An excellent on-site engineer mainly relies on the accumulation of work experience, which has little to do with personal talent. As long as they are diligent and have done enough projects, the vast majority of people can become an excellent on-site engineer.
If someone engaged in PLC technical support wants to start system debugging on site, whether it is for OEM customers or for the integration of a process control system, they must make some preparations in advance.
Firstly, you need to arrange your own itinerary plan, clothing, food, housing, and transportation. After settling in, prepare your own tools. As an on-site debugging engineer for PLC, I don’t need many debugging tools. However, a screwdriver and a multimeter are still essential. In addition, when conducting system joint debugging with on-site instrument sensors, a signal generator is also required to simulate the signal of the on-site instrument to ensure that the on-site signal is intact when a problem occurs. Also, a sturdy laptop is a necessary tool for programming and debugging. Although you can require users to prepare these tools, as a professional PLC engineer, if you don’t even have these tools, users will doubt your professional level.
There are some small things that are often overlooked that will definitely be useful when you prepare them. For example, electrical tape, heat shrink tubing, lighters (if you smoke, you naturally have them), cable ties, and if the on-site wiring is already completed, prepare some cables that are the same as the signal wires, as well as some screws to fix the base.
If the system design is not done by yourself, then before departure, it is necessary to have sufficient communication with the system designers. For unclear and unclear areas, it is important to clarify them to ensure that you have a clear understanding of the work objectives to be completed and the designer’s intentions. Don’t easily deny the designer’s plan, nor easily say that others’ design is not good.
In the design of the solution, the most prone area to problems is communication, and the most troublesome part of on-site debugging is also communication. Therefore, for the communication part, you must have a clear understanding of the system’s framework structure, and debug everything that needs communication before departure, and confirm that all modules that need communication can communicate.
