Manually Add Signal Numbers

If required, you can manually assign a signal number on any terminal by double-clicking on the Signal Number field. This removes the 'read-only' property from the signal number. The users may then enter a different number.

Importing or updating a signal number from Excel (see Import Signals from Excel) has the same affect.

Note: Signal/wire numbers assigned to terminals remain on their terminal regardless of which wires are terminated. You should only assign signal/wire numbers to terminals that carry a permanent signal for example, a Field Device . However, there are valid situations where you may need to permanently assign a signal to terminal in a terminal strip, such as picking up a motor run contact from an interposing relay cabinet or from an MCC. In this case there is no 'Field Device'.

Remember that signal numbers are inherited by all wires/cable cores that are connected directly to a terminal containing a signal number, and wires connected to a wire that has an inherited Signal Number. Refer to Wire Numbering for further information.
