Hi I am looking at mid range plcs to try and get something cheaper than S7-300 type.
It must support profibus (maybe as an add on would be fine)
It must be ethernet capable
It must support SFC/Structure text/Ladder
It must be able to support a minimum of 10 PID loops, ideally self tuning
Apart from that it must be cheap.......
I am looking at Omron site and seem OK so far.
S7-1200 seems to be inadequate for all of the above especially programming languages
Interested to hear opinions
