Hello risingedge; You can use any screw-type Profibus connector, as long as you group all the stranded flexible wires in a ferrule: SIMATIC NET PROFIBUS Networks(from Siemens) PROFIBUS flexible cable 6XV1 830-0FH10 The flexible cable 6XV1 830-0FH10 complies with the specification EN 50170, Cable Type A, with stranded copper cores (approximately 24 gauge - 19/36) apart from the higher loop resistance.This difference means a reduced segment length; refer to the table in Chapter 3 “Notes on Configuration”. In contrast to the standard LAN cable, the cores of the flexible cable are of stranded copper. In conjunction with the special combination of braid shield, foil shield, fleece layer and the sheath material of polyurethane, the cable has a torsional strength of +/-180o while retaining highly constant electrical characteristics.The cable has been tested to a minimum of 5 million torsional movements on one meter cable length (+/-180o) .If screw terminals are used, the stranded cores must be fitted with wire-end ferrules (0.25 mm2 complying with DIN 46228).The bus connector 6ES7 972-0BA30-0XA0 cannot be connected.The cable is not suitable for use of the FastConnect (FC) stripping tool. See also this recurring note in section 4.4, "Attaching LAN cable to the Bus Connector": NoteStranded cores must only be used in screw terminals with wire-end ferrules fitted (0.25 mm2 complying with DIN 46228). Use only wire-end ferrules made of materials with permanently stable contact properties, for example copper with a tin-plated surface (not aluminum). PROFIBUS Installation Guideline for Cabling and Assembly (from profibus.com) 2.4 Flexible PROFIBUS cables The cores of flexible PROFIBUS cables consist of many fine strands. In general, stranded cores should be fitted with wire-end ferrules (boot-lace ferrules) to keep the strands together and prevent them shorting. In many cases, however, the screw terminals on PROFIBUS components are designed to directly accept stranded cable without wire-end ferrules. To determine whether the screw terminals can directly accept stranded cable without a ferrule, you should compare the terminals with the following two figures... Hope this helps, Daniel Chartier |
