Hi guys, I am new with PLC programming so I want your lights.. We suppose to install a flowmeter( with analog current output 4-20mA), after an on/off solenoid valve. Connecting the flowmeter to AI module I will get indication in SCADA for the flow. My question is that I want a Set Point for the flow, below which I will get 1) an indication of alarm in SCADA , 2) an output signal for the alarm to activate a signaling device and 3) 1 and 2 only when the valve is open.We use Siemens PLC. Any relevant information or basic steps for how to do the programming part will be helpful. Thank you in advance
