Level Switch for 1 to 5 stages (Fb_SwitchLevelX)Function Description:The function block Level Switch is available in the library in a 2-5 level version.It compares an analog input value “iInput“ with the threshold values “iSetp1-iSetpX“. If a threshold value + hysteresis/2 is exceeded, the corresponding level 1-Xis set to “1“.The input value can fluctuate within the hysteresis without the level output changing.The hysteresis applies jointly for all threshold values.If the threshold value - hysteresis/2 is less than the threshold value of the lower level,the next level below switches on.It is not possible to have several levels set to “1“ at the same time.A delay time for switching between the individual levels can be entered as a defaultvalue via parameter “uiTd_10tel_s“.The threshold values must be entered in an ascending order. If this rule is notobserved, a message will be emitted via the “Error“ output object.Example:Hysteresis = 2iSetp1 = 2019 xLevel1 = OFF21 xLevel1 = ONiSetp2 = 2221 xLevel2 = OFF23 xLevel2 = ONiSetp3 = 2423 xLevel3 = OFF25 xLevel3 = ONiSetp4 = 2625 xLevel4 = OFF27 xLevel4 = ONiSetp5 = 2827 xLevel5 = OFF29 xLevel5 = ONIf possible, the spacing between the threshold values should have the same value asthe hysteresis.Subject to design changes WAGO Kontakttechnik GmbH & Co.
