micro controllerer out put handling capacity is low,i hope you know about fan out
for example micro controller cant control a induction motor directly,but plc can control ,it has the ability to hand such kva capacity,but the funny thing is inside the plc there are combination of microcontrollers,dont get confuse,these controllers has been specially designed and supported by sufficient hardware,
so you can understand main difference is additional harware support to handle larage currents and voltage spikes,
an microcontroller output will be 0v or 5v and it can handle only few micro amperes,
so can you control a motor or robotic arm or any indicating bulbs,or solonoid relays?answer is no you cant,,you need more power.so the controller out put is being amplified to without distortion ,and doing the same job which was determined by the controller but it cant do it alone without power amp.

∙ 12y agoThe softwiring advantage provided by programmable controllers is
tremendous. In fact, it is one of the most important features of PLCs.
Softwiring makes changes in the control system easy and cheap. If
you want a device in a PLC system to behave differently or to control
a different process element, all you have to do is change the control
program. In a traditional system, making this type of change would
involve physically changing the wiring between the devices, a costly
and time-consuming endeavor.

Is using grey water a good or bad for the environment?
Because "black water" means "water that we can't use", and "grey water" means "water that we can use".The definition of grey water is that it is waste water that is safe to use (other than for drinking) without treatment. The definition of black water is that it is waste water that requires treatment before re-use. If you have water that you can use, then by definition it isn't black. If you have black water, then whatever reason that it is black is the reason that you can't use it.
