2 pcs optocoublers are turned in one direction, 1 pcs optocoubler in the other direction. When the block is inserted on a schematic the direction is changed to one direction for all 3 optocoublers. I am looking forward to continue with the pro software:-) I have some projects to convert to pro and use the feature of reuse block, are there any best way to do this? For me it seems that the net labels can give some challenges.
