With DNP332 and Zenon 7.0 SP0 build4, I have problem with trend. If i lose the connection between Zenon and PLC. Zenon keep drawing line and if i change value offline ,When i reconnect Zenon and PLC , i can not get trace of the change that was offline. How i can fixe this problem?
because for bool variables, if i do same change offline, when i connect back i can see this events in CEL with the right time stamp.
So i wonder how we can do the same thing for analog values in trend
Thanks for your help
