LIM_HYS_Set = 0 è LIM_HYS interpreted as a percentage value LIM_HYS_Set = 1è LIM_HYS interpreted as an absolute value LIM_HYS interpreted as a percentage value depends on the range of values defined by the HI_LIM and LO_LIM parameters and is converted accordingly. The value of the hysteresis is mirrored to the QLIM_HYS output and influences the deactivation of the triggered limit monitoring messages: Messages relating to an exceeded limit: these messages are deactivated only after the limit minus the hysteresis has been reached. Messages indicating that the value has fallen below a limit: these messages are deactivated only after the limit plus the hysteresis has been reached. Entry ID: , V1.1, 09/

15 3 Functional Mechanism of this Faceplate 3.3 Control and status signals Enabling/disabling the simulation The Simulation ON mode enables the simulation of the analog signal. This function is important, for example, if automatic functions shall be tested already during the configuration phase, although a process interface does not yet exist. Without simulating the feedbacks, many automatic functions (e.g., step sequences) cannot be successfully executed since the feedbacks are frequently requested in step enabling conditions or cause errors.
