why cant I write to D9?

4 posts in this topic

Working on this program here for GX developer. For some reason I can not write a value into D9 with an HMI nor with the entry data monitor with the HMI disconnected. Appears to be a compile time issue. prog.zip

You are using a MUL instruction with output D8. MUL instructions output the data in 32bit format (you specify the starting device and will automatically also write to the next variable....). Se picture. The MUL instruction will overwrite BOTH D8 and D9 when active.
