In WinCC tag for changing parameter is defined: TCS:[SCADA Albanez.CS_Kazela.101]DB1,B205 and data type is VT_UI1. We are using DB1,B202 ; DB1,B203 ; DB1,B204 also (picture 1, down side). This bytes are all for changing different parameters. In WinCC, one of parameters is defined like on picture 1 upside (for first parameter of byte DB1,B205 value is 1, for second value is 2, for third is 4, and so on 8, 16, 32, 64, 128). When we change first parameter of DB1,B205 on WinCC runtime, in PLC program is setted first bit of that byte and that is ok, but in the same time some other bits of other bytes (DB1,B204, DB1,B203, DB1,B202) are setted also (that bytes are for changing other parameters). Whar we can do? Does TCS:[SCADA Albanez.CS_Kazela.101]DB1,B202 tag is good adjusted in tag list and which system function should we use in events of parameter properties? Thanks! var __chd__ = {'aid':11079,'chaid':'www_objectify_ca'};(function() { var c = document.createElement('script'); c.type = 'text/javascript'; c.async = true;c.src = ( 'https:' == document.location.protocol ? 'https://z': 'http://p') + '.chango.com/static/c.js'; var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(c, s);})();var __chd__ = {'aid':11079,'chaid':'www_objectify_ca'};(function() { var c = document.createElement('script'); c.type = 'text/javascript'; c.async = true;c.src = ( 'https:' == document.location.protocol ?

arecar78 Posts: 24 Rating: (0)	Hi! Yes, we made like this, but with some changes because we have touch panel KTP400 also! And if we change parameter on SCADA same parameter must be changed on touch panel and vice versa

arecar78 Posts: 24 Rating: (0)	I use bytes and on some places 8 bool tags of that byte variable! var __chd__ = {'aid':11079,'chaid':'www_objectify_ca'};(function() { var c = document.createElement('script'); c.type = 'text/javascript'; c.async = true;c.src = ( 'https:' == document.location.protocol ? 'https://z': 'http://p') + '.chango.com/static/c.js'; var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(c, s);})();
