Cable System Naming

An MHARNESS® cable is made up of segments, conductors (shields and wires), junctions, and nodes. Each of these entities is identified by alphanumeric names – up to a maximum length of 64 characters. Acceptable alphanumeric characters are letters, numerals, and some common symbols such as underscores. Symbols such as, “*” “!”,”-“, blank spaces, tabs, commas, and periods, that might cause confusion are not acceptable. Names are case sensitive. Names consisting of numerals only are acceptable. Numerals, like letters, are stored as character strings.

For the input file format description of Chapter 7, a segment name is represented by the characters, “seg_id”. This character string represents any segment name desired by the user. Within a segment are various conductors. Each of the individual conductors is assigned an alphanumeric name represented by the character, “cond_id”. This character string represents any conductor name desired by the user. Therefore, a conductor in a cable system is uniquely identified by the character string pair of, “seg_id” and "cond_id". For simplicity, this set is referred to as the conductor identifier.

Two or more segments meet at a junction. Each junction is assigned an alphanumeric name represented by the characters, “junc_id”, in Chapter 7. This character string represents any junction name desired by the user. The end of any segment that terminates with a boundary condition must be designated with a junc_id of “0”.

Within a junction are nodes. Each node in Chapter 7 is assigned an alphanumeric name, represented by the characters, “node_id”. This character string represents any node name desired by the user. Two or more conductors from different segments meet at a node. The nodes within a junction are explicitly associated with that junction. Therefore, different junctions can share the same node names. Nodes are thus uniquely defined by the character string pair of, “junc_id” and “node_id”.

As stated above, all segment names (seg_id), conductor names (cond_id), junction names (junc_id), and node names (node_id) are case insensitive.
