I have performed migration of HMI project from .pdb to .hmi and changed panel from OP170B to OP177B, with the use of WinCC flexible 2008 SP3.
When I connect panel to the plant, everything is looks like OK, plant operate, no alarms etc., but it is not possible to change set points.
I change set point of parameters on Setting Screen, but when I return to work screen with this parameter, it remains the same.
The procedure of settings (which keys for increasing\decreasing of values, enter, esc etc.) on new panel is the same as on old one, I didn't find any new features...
It looks like HMI cannot overwrite new parameters in PLC memory.
What can be reason?
