Lukas Posted October 8, 2012 Report Share Posted October 8, 2012 I found that is a problem with on screen variable Real Time Clock that display only current date (day, mont and year). When I change for example a year thru program (in background) - value displayed in this variable isn't changed - I must manually refresh display. (Problem detected when debugging RTC synchronization by CAN). Also I have an idea to add in UniCAN communication a new function - synchronize RTC. This function would be veru usefull when using multiple PLCs. Quote Link to comment Share on other sites More sharing options...
AlexUT Posted November 8, 2012 Report Share Posted November 8, 2012 Hi, Time synchronization really means hours/minutes/seconds update. And O/S take care to update this field as it changed (each second). O/S take care to update date field if it is changed from clock. You update date/month/year manually, so you have to use SB 31 "Refresh current LCD screen display variables". This can not be defined as Bug. You dont need a new function for CAN. Use broadcast and send corresponding SI to update at all connected OPLCs. BR. Quote Link to comment Share on other sites More sharing options...
