Excellent topic. I too am fond of Mitusbishi PLCs but wish for a few changes in GX Developer: - Drag & Drop label variables to ladder instructions - Tool tip showing instruction requirements as I'm typing instruction (similar to ST) - Cross Reference that finds ALL instances of address/label including in ST routines - Individual Comments for each element of an array - Ability to pass (move) Structures - Ability to create nested structures - Function Block Diagram - Ability to export Labels in CSV format I think that GX IEC Developer has all or some of these functions. I sure wish that I could get my hands on it to find out.
