welcome everybody
I have a question about how to control the engine speed through PLC
By sending the frequency from the memory number (for example: VD100 = 50 , 60 , 70 or 100) on the HMI display connected to the PLC and then to the frequency inverter Responsible for determining engine speed using (RS485 or RS 232)
Recommended : RS 232
My tools:
1- Plc ( CPU 226 - 6ES7216-2AD23-0XB0 )
