Profinet s7-300 and phoenix contact

Dear Experts,

i try to make comunication between a s7-300 (ag14)+ cp343-1 and a phoenix contact PROFINET  (IL PN BK DI8 DO4 2TX-PAC) decentralized module

all work fine for digital in/output .

But i have some difficulty with analog input (IB IL AI 2/SF)

see on picture the function block is running but the value is allway on zero

somebody can help me ?

thanks in advance

Fred

Hello,

I expect click on that PN device and configure needed settings. Did you configure/set something to that AI? I see some addresses I/O of that module, so probably also AO can be set...

Hello,

The profinet network  still working fine with the digital input (device name/ip/input adress)

the analog (IB IL AI 2/SF-PAC) module have only 2  inputs 0-10v (no output)

i cant read analog value

there is my setting in attachment

thanks

hi fred_vigan

you have to read the Periphery on the CP with FC11/FC12.

I guess your block is trying to read from the CPU´s Periphery. See the following FAQ how to read the I/O from CP:

How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?

hope this helps,

regards,
