I’m an industry service engineer for food packaging machines and never an automation specialist, but i can give you few hints.
For all automation systems to work, you should first use a clear and detailed mechanical plan wonderful details finalized. When you accomplish that, you need to specify the sort of motions involved, e.g.: linear or rotary. This enables you to be aware of number and kinds of motors and actuators you need(servo, ac single phase, ac 3 phase, pneumatic actuator).
For each and every motors you will need relay contactors (for single speed discrete/on-off type motors like blower fans and liquid pumps), VFD for speed controllable ac 3-phase motors(a lot more like conveyors, liquid tank level control pumps or rollers).Servo motors need Servo drivers to manage their precise movement.
These are generally your output devices, then you need your input devices to become lay out. This is level sensors, flow sensors, proximity switches and also other devices when needed. The reason i’m stating out this routine would be to enable you to define the specifications essential for your control system hardware requirements. All PLC manufacturers layout their product line-up based on system complexity.
Most PLC hardware is sold as reconfigurable rack chassis. Basically there is an CPU the actual master brain that is supplemented with I/O device that could be slotted in like cards. Additional complex systems which needs servo motor will have servo card to get in touch with servo driver, communication bus cards like CAN-BUS, PROFIBUS and DEVICENET and sensor cards for special sensors like RTD temperature sensors and level sensors.
So work out you IO devices list, then receive the necessary software and hardware needed. You will need additional hardware needed for for fancy touchscreen display HMI, line automation an internet-based diagnostic and asset monitoring functions. That’s that the guy with mechanical background can approach complex automation problems.
The solutions may vary determined by different manufacturer offering especially if you use beckhoff based systems. A great way to start is to develop existing machines so that you can study the basics. Go have a few catalogs from reputable manufacturers to understand the market industry is offering. I suggest website visitors to go through Omron catalogues. Next to your skin a totally free automation web based course that can show you the newborn steps needed.
You need to be capable of design complete PLC systems: architecture design, hardware specfications and selection, logic narratives, logic programming, connection drawings. Everything. Perhaps you simply need some additional training for the details of each bit of it technology, concerning how to program or properly connect them, yet it’s not nuclear physics, a good mechanical engineer should probably excel for this because other engineer. The main element of control system design is to see the process you’re going to control as well as the goals you would like to achieve.
