Hallo everyone, I am using WAGO PFC100 as hardware and Codesys as software. I am trying to read the CSV file and get the values from that.
The problem is, the function blocks (with out license) csvReaderInit and nextElement were functioning well in simulation mode and give correct results. But those are do not work in the online mode (login). It shows error in a function block.

Question: Does the csvUtility function block work in PFC100 or not? Or because of free usage of function block?

Hi,
sure should work, we need more details, scereenshot error numbers... and this should work even in the 2h unlicensed mode.
Which Runtime/CODESYS Version and which Wago Firmware is on the PFC100?

Regards
Edwin

Hallo Edwin,

My csv content are:
