I know that topic description may sounds strange, but it's a strange application that i have in mind.
Well, i have about 20k analog signals to be measured, and i think to use a multiplexor commanded by four digital outputs for use just one analog input.
The information received by my plc must be put on a database later.
The question is, what is the proccesor speed of AB PLC's on market?, with that amount of info, is possible to use Sql database? or would i need another one like oracle?.
If you think that i'm wrong let me know please,
Thanks
