Hi,
We use the FMD 16 PLC for a control system and we also utilise the web server function, both work well.
We recently supplied some additional panels which have the same PLC in each but the PLC FW in one panel was r77 and r78a on the other.
The PLC program works the same on both but the web page on the PLC with the later FW shows an asterix (*) on the LCD at the end of the LCD line text see pic.
Any ideas?
