Functional principle

With the external processing unit type FM-IM- …FX, all non-Ex flow sensors of the FP100 series (immersion sensors) can be operated. The flow module features four status LEDs as well as a 10-segment LED band for local monitoring. Software-based diagnostic options are also available to the user, such as wirebreak and short-circuit on the sensor side. Furthermore, monitoring of flow rates and media temperatures within a predefined operating and display range. The upper and lower limit are determined in relation to the analog output signal and taught in using the implemented teach mode. Working on the calorimetric principle, the connectible sensors not only detect the flow rate but also the media temperature. The flow module can be operated either in IO-Link (IOL) or in standard IO (SIO) mode via the integrated IO-Link interface. In SIO mode, the switching outputs are operated in the standard way. In IOL mode the current process signal is transmitted cyclically as a 10 bit-serial value. Parametrization is initiated either via pushbutton or software-supported via IOLink interface. The actual parametrization is then implemented via the tool-based DTM or IODD within the FDT frame PACTware™ or acyclically near the control via On-Request Data Objects (ORDO).
