The sensors are not powered via the module, but via a reverse-po- larity protected auxiliary energy which is fed separately via the terminals to the channels 1 … 4 (group 1) and 5 … 8 (group 2). The in- put groups are galvanically isolated from each other. The input behavior is parameterized via the Fieldbus master. Possible parameters are switching behavior (PNP or NPN), polarity, substitute value strategy, wire-break monitor- ing, short-circuit monitoring and flutter moni- toring. Flutter monitoring detects and reports proce- dually unusual signal patterns, for example too frequent fluctuation of the input signal be- tween "0" and "1". The occurrence of such signal patterns is an indication of faulty sen- sors or process-related instabilities. For each input channel there is a parametriz- able monitoring window. With the first signal change of the input signal, the monitoring win- dow is started. If the input signal changes more often within the monitoring window than the configured number of signal changes, this is recognized as a flutter error. If no flutter er- ror is detected within the monitoring window, then the monitoring window is started again with the next signal change. If a flutter error occurs, the current signal sta- tus is entered in the process image and the value status of the signal is set to "invalid". In addition, the diagnostic information "flutter error" is entered and an incoming diagnostic alarm is triggered. The value status and diag- nostic information can be evaluated and pro- cessed in the user program. If no more flutter- ing of the input signal has been recognized within the triple monitoring window, the diag- nostic entry is removed and an outgoing di- agnostic alarm is triggered. The status of the current signal in the process image is set to "valid". ■ Input module for 3-wire sensors (NPN and PNP) ■ Supply of sensors reverse polarity protect- ed via auxiliary power
