Please also see the attached screenshots. We are using 4 sets Schmersal safety switches (similar to SIRIUS RFID Safety Switches) on a machine. They are working in two pairs (left and right bumper bar). Each of the switches are connected to a FDI input that is set up as a single input (so no discrepancy time). Schmersal has issued a new version of the detectors replacing the old model and claiming there is no difference. When we only replace one set of switches (so we have one old and one new) it is still working however when we replace both of the switches (so we have two new) it stops working and gives a short circuit error. I can see that in the Siemens manual it is mentioned that "Sensor supply: externally or using a module without short-circuit test (internally, block short-circuit test)". I hope that will solve the problem even though I think it is strange that I need to do it when only replacing the sensors with supposedly similar sensors. But - what will it mean for the functionality of the rest of the FDI channels that I disable the SC test for the second Supply group? AttachmentSC test.zip (245 Downloads) |
