The element <contactOrderValue> is used to order the wire ends, connected to equipment with internal logic, in addition to the termination module, block and shunt grouping information.All wires, which are not connected to base contacts of switches and relays, must get values higher than the values of base contacts. In this case, the base contact (supply) will be shown before the different positions of the switch/relay in the graphical presentation of the wires connected to this equipment.When more than one wire is connected to an electrical potential, all these wires must have the same content in the element <contactOrderValue>.
