Hello Daniel; The analog input module 6ES7331-1KF01-0AB0 does not have range modules on the side, as other modules may have. What you must validate is whether the hardware configuration for that module has been correctly setup (in HWConfig) and whether the wiring of the input sensors corresponds to the type of these sensors: - do these sensors have their own external power supply?: use 4-wire transducer wiring - are these sensors powered by the AI module on the PLC?: use 2-wire transducer wiring See the attached screencapture, taken from an older version of the following downloadable S7-300 Module Data manual that still has information on the module you are using (it was discontinued in 2012). http://www.allmar.pl/upload/files/s7300/S7300_modulesdata_en.pdf Hope this helps, Daniel Chartier |
