Hello everybody,

I'm testing a CP343-2P with a 313C CPU. I mount a test installation in my desk. I configured the system in TIA V14. I'm not using a AS-i power supply but a normal power supply regulated to 30V. The CP runs normally but don't detect any slave. In online diagnostics it shows 2 errors, cable error and configuration error detected. I connect power supply on terminals 19-20 and the only one slave in 17-18. Slave is already addressed with address 2.

I can't find any problem here and in CP manual don't refer nothing regarding TIA. The CP and the slave are new. The PLC has an empty program. For now I only want to detect slaves. Can the power supply be the problem?

Regards,

Nuno

Jupp, this is I also want to say to use. For As-I, you need special AS-I Power or a data coupler like
