Hi,
I am currently working on a thesis on programming a basic process tank, I need to control the servo valve and solenoid valve so that the water can reach the desired setpoint. However, I encounter some problems along the way. The solenoid valve requires a 24volt voltage to be switched on and the servo valve requires a 20mA current to be open. I wired the solenoid valve to one of the embedded output on the PLC and wired the servo valve on the analog output on the PLC.
My questions are
1) Would the embedded output of the PLC be strong enough to turn on the solenoid valve?
2) Where should I wire the solenoid valve onto? Com or O1, O2, O3 ?
3) How do you program the plc to output an analog value to the servo valve from the analog output?
4) Can someone please tell me what is the characteristic of the embedded i/o? EG, if I assign a Boolean “1” on the output what would happen to the com / output?
Thanks in advance =)
