Hello, Make sure you have the right addressing, look in your hardware config. Standard i believe the digital I/O start at adress 124. Did you connect the 24 V supply to the I/O cards? For connection details: SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Regards, Marcjan |

Dear Marcjan Thankyou for your help but I am having no problem in the simatic manager. I have done all the hardware configuration in the Simatic manager. Address for input realy starts from 124 to 126, but problem is with the card somehow i cannot figure out what. Regards Freeze

Hello, For sure you need power supply for inbuilt I/O. Basically TonVeera suggestion is correct. Wiring of DI/DO - Wire the CPU Wiring of AI/AO - Wire the CPU Wiring of Counters - Wire the CPU Best regards, Hristo Mihalev |

There is no back plane connection for integrated I/O modules.

Dear Ste39, Gone through the manual, need to clarify two things: 1. I have given the feeding power to the terminal-1 (24V DC) & terminal-20 (0V) of X12 (second module), Is it neccessary to give feeding power to all power feeding terminal i.e. terminal 21 to 24V DC, terminal 30 to 0V DC of X12 etc. 2. Is it nessessary to have DI address 124..126 and DO address 124..125 since in my project I am having 1..3 for DI and 124..125 for DO Reg, Ashish

Hello,
Yes, if you leave the adress default the adres is outside the Proces Image and can't be monitored in a VAT. You can either change the adress to a lower one or increase the PI if possible. Where and when do you need peripheral addressing? Regards, Marcjan |
