Hello soussia; Your CPU 313C has5 analog inputs,four of which can be wired for 0-20 mA signals, and are accessible at addreses PIW 752 (channel 0), PIW 754 (Channel 1), PIW 756 (Channel 2)and PIW 758 (Channel 3); PIW 760 (Channel 4)is reserved for temperature measurement. The attachment contains an extract from the following manual, showing how to connect the 4 analog input channels. Use the I and C connections for current reading; connect all analog commons to Mana (pin 20) and short all unused channels to their common; this will help reduce noise on the analog channels. SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Hope this helps, Daniel Chartier |
