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.
