[Problem on 4-20 mA output]

Power supply is connected as per pag 7 scheme (0V connected to 0volt and V2 Coinnected to +24DC).

I dont know anymore what to do.

Thank you

Hi Sgull, thank you for your reply.

I connect power following the scheme on manual as per your indication and 0V is common for all channels. Moreover power used for channel is the same used to power up V700.

I already tried to scale the signal to 819 - 4095, but minimum current coming out it is always 15 mA. Could it be that snap-in module has problems?

 

[Problem on 4-20 mA output]

Hi everyone,

we are writing because we are jammed on a problem that we have with our Vision700 + V200-18-E6B snap-in I/O module.

The fact is the following:

we setted up hardware as following:

AN0 = 0-10V output with MI0 variable

AN1 = 4-20 mA output with MI1 variable

On ladder we provide linearizzation for 0-10 V from 0 to 4095 bit and for 4-20 mA from 814 to 4095bit.

when all wiring is setted up following the scheme reported on the manual we measure right voltage (that is generated by using a text box on HMI in which we put bit value), but for current output we measure alsways a minimum value of 15mA.

we double check connection and we also tryed to switch channel but the results are always the same.

Do you have any suggestions?

we attach vlp file for your comments.

Thank you for you kind attention
