Hello Peter; How are the sensors wired? Does your wiring match the following schematic (taken from the manual SIMATIC S7-300 S7-300 Module data)? That means 24 VDC power to pins 1 and 20 of the analog module, 24 VDCpower to each sensor, + and - signal inputs to unsused channels wired in series with the used ones... This lastinformation comes from the same chapter: 6.7.3 Additional information on SM 331; AI 8 x 12 Bit Unused channels … · Current measurement 4 mA to 20 mA, 4-wire transducer: wire the unused inputs of the same channel group in series. Hope this helps, Daniel chartier |

Hello, here are the wiring of the abb drive and the analog input. I don't think there is anything wrong with it. Greetings, Peter Attachmentwiring.zip (244 Downloads) |
