Hello guys,
I need your help again. Haven't did anything with PLC for a long time, but now I have some little confusion.
Equipement: Siemens 6ES7144-4GF00-0AB0 and pressure transducer is connected to give 4...20mA, 0-300psi.
Pressure transducer is changed with brand new one. I didn't check wiring, but...
Channel 1 is used to read 4...20mA. Raw counts on HMI screen is showing all the time 32767, doesn't matter if pressure is being changed. Is it possible that PLC is showing max raw count if + and - terminals are being swapped??? Doesn't look like to me, but better to ask professionals.
