Content	220Functional Example No. AS-FE-I-005-V10-EN Ex. No. For calculating the max. reaction time of your F-system please use the Excel file (Cotia table), which is available for S7 Distrib- uted Safety V 5.3. This file is available on the internet: http://support.automation.siemens.com/WW/view/en/ 19138505 Muting In this example we show parallel muting. Muting is an in- tended suppression of the protective function. This is e.g. re- quired during transporting the material into the danger zone. Muting is triggered by muting sensors. In this example, FB189 (F_MUTING) is called in the F program (FB 1, DB 1). Among other things, FB189 as input parameter has the signals of the four muting sensors (MS_11.MS_22) as well as three param- eterizable times (DISCTIM1, DISCTIM2; TIME_MAX). If the muting sensors MS_11 and MS_12 are activated by the product within the time DISCTIM1, the muting mode is acti- vated. The muting mode remains active as long as MS_11 and MS_12 are activated by the product. The product may pass the light curtain without causing a stop of the machine. Before the muting sensors MS_11 and MS_12 switch inactive, the muting sensors MS_21 and MS_22 must have been acti- vated within the time DISCTIM2. This ensures that muting mode remains active. The muting mode is terminated, if one of the muting sensors MS_21 or MS_22 is switched inactive by the product. The maximum time for the muting mode to be active is TIME_MAX. Note Muting mode also becomes active if the muting sensors MS_21 and MS_22 respond first. Active muting operation is indicated by white indicator lights. In this example, one indicator light is used to display the mut- ing mode. The diagram below illustrates the relations during muting mode with regard to time. P 2 2 P 2 2 P 2 ! D 2? 5
