Dear Experts, Can anyone give me an example wiring or connection of a PT100 temperature sensor to a SM331 8 AI 13 BIT (6ES7331-1KF01-0AB0) module? On our existing application we directly connect the sensor to the AI module. 6ES7331-1KF01-0AB0 AI module has only two types of configuration for Temperature Sensors. I selected the R configuration and chose 600 ohms. When we terminated the wire to the AI channel, we only get half of the actual temperature reading. What I did was to adjust the range of my C- measure block from 150 degC to 300 degC and got the actual reading. Is that acceptable? The temperature sensor range is 150 degC only. Is it correct to use the R configuration for PT100 sensor reading? Ive also tried using the RTD Thermal Resistor configuration and have chosen PT100 Standard but still dont get the actual temperature reading. Instead Ive only get 3 to 4 degC reading on my C- measure block. We also tried to measure the resistance of the wire from the sensor. What do we need to do to get the precise and actual temperature reading using the existing AI module (6ES7331-1KF01-0AB0)? Suggestions ,procedures for troubleshooting and testing would be highly acceptable. Hope someone can help me with this issue.. Thanks and best regards, LGM Siemens Inc.

New question published by ShoaibZaffar is split to a separate thread with the subject RTD (Pt100) on 6ES7331-1KF01-0AB0 connection. Best regards |
