From time to time I have some customers who needs PLC HMI on Russian.
Some time ago Tonary descibed problem about Cyrilic on U90 Ladder and Jazz PLC.
So I have the same problem as Tonary, exept that I have Windows Vista. I downloaded the latest version of U90 Ladder and change all regional settings to Russin and in Ladder project language to Russian too. In Ladder project symbols on display still are "mysterious" , but on PLC OK.
What I have to do to see Russian symbols in project?
