Hello all!
I have one problem and i need an advice. I search for fast plc, that could have minimum plc cycle.
I got 2 inductive sensors 0-10V (0.5 - 2mm). I connect this sensor with plc.
On plc is connected shaft encoder which is 360ppr. My task is protech a stamping tool betwen stamping and if inside tool is some bad stamping pease we muss stop stamping.
i control heigh of the stamping tool with inductive sensor. Right moment for measurement i get from incremental encoder.
For example:
I want to measure highof the tool at 90° - 180°, so when the tool if fully pressed.
Now i have Unitronic plc with plc cycle cca. 2.5 mS and only one interrupt at 1.25mS and HSC interrupt at 359° (for reset at 0).
But this plc is to slow for this application.
Machine run at 200 rotations per munute, so i need interrupt less then 1mS (for one degree accurity).
SO i need fast plc that can do dhose things fast.
1. interrupt for hsc for set counter on 0
2. set interupt for hsc at 90° (at rising edge) (for high measurment
3. interrupt for analog input? I need fast AD conversion so that i can check for high of the tool every one degree.
so which plc shuld i use?
