hello all, I've an s7-1500 module {AI/AQ 4xU/I/RTD/TC / 2xU/I ST (6ES7 534-7QE00-0AB0) }. I want to have it configured for 2 wire resistor. The connections for resistors are in attachment. pin 3 with 7 and 4 with 8 are shorted. The two wires for sensor are taken from pin 7, 8. However, I get an input of 32764 (maximum Analog input value) for the tag, and the values does not change with change is resistance. The multi-meter shows the change in resistance as temperature varies, which is a confirmation that the sensor works fine.. ------------------------------------------------------------------------------------------ |

hi, do you have a PTC resistor, as you projected? have a look in the manual, how to handle it with PTC-resistors, or in the attachment. hope this helps, regards, AttachmentSpecial features for the use of PTC resistors.pdf (213 Downloads) |
