Schematic and panel layout/wiring diagram terminal symbols can carry TERMDESC attribute values used to control which side of a terminal is to receive internal or external wire connections. Schematic terminals use attributes X1TERMDESC01 for the right wire connection, X2TERMDESC01 for the top, X4TERMDESC01 for the left, and X8TERMDESC01 for bottom wire connections.
i.e Term #1 is on the left, X4TERMDESC01 is used for wires coming in from the left.
Term #2 is on the right, X1TERMDESC02 is used for wires coming in from the right.
Notice I changed 01 in the definition above to 02. This will give you one wire number/wire on one side and a different one one the other.
If you want the same wire number through the block, keep the X?TERMDESC01 designations on the terminals.
For more indepth info, go to the contents tab of the help file, select creating library symbols, this will give you a good base for understanding symbol creation.
Good luck
