Clopedandle Posted December 1, 2016 Share Posted December 1, 2016 Do PREAD and DREAD execute synchronously (i.e. their calculations complete before the calling PLC advances)? Or do they require some delay after being issued before reading the positions in D-Variables? Thank you. Link to comment Share on other sites More sharing options...
steve.milici Posted December 6, 2016 Share Posted December 6, 2016 They do require a finite time (probably very small) but note that when both are used in the same “thread” they will use the same D-variables. Link to comment Share on other sites More sharing options...
