I have designed a few control systems, but always for some factory environment. Now I'm facing a new challenge. I need to build a control system for some mobile equipment. The task is in short to modify a small lorry truck and build some machinery on top of it. It's a farm machine that must be allowed for a lot of beating, dirt, water flushing and all kinds of abuse. It's going to be a rent out machine. Nothing wrong said about farmers, but I expect it will not always be treated nice.
Any of you with experience on building such auxiliary control systems for vehicles? I have questions regarding just about everything: Enclosures, power supply, buttons and handles, weather resistance, vibrations and not the least: which controller should I choose? I have most experience with Siemens S7-200 and S7-300/400. I also have some experience with several Allen Bradley types. But for me these PLC systems appear to be far too delicate, likely to fall apart by hitting the first pot hole in the road.
