Hello, The error "I/O access error writing" means the CPU can not write the address '0' So please check if I/O address '0' is available. (It could be used in a Profibus device, that is not available) The error of Analog input card, check the manual why the SF led is turned on. SIMATIC S7-300 S7-300 Module data Best regards, Wizard |
