I have an S7-1211 with an analog board on it. I have configured the filter to 400Hz 1 cycle and i take the reading when an interrupt is generated by an HSC. Before I have not seen the setting of filter frequency, so now with the correct setting the results are better. At half the required cycle frequency the result is fairly ok. Does exist some way to set the filter frequency to 1 KHz ? We are planning to use many PLCs configured in this way to measure the peak value from a load cell. The signals are as in the scope wiew attached. Pin O- is connected to M terminal of the PLC, ground terminal of the PLC il left open. The system is on a test bench.
