Preassembled Industrial Twisted Pair (ITP) and
Twisted-Pair (TP) Cables
Use of Preassembled Cables
Preassembled SIMATIC NET cables are available to connect DTEs and network
components.
Industrial Twisted Pair (ITP) Cables
Preassembled Industrial Twisted Pair cables are intended for direct links (without
patch cables) of up to 100 m in length between two devices.
Due to the double, extra thick shielding, Industrial Twisted Pair cables are
particularly suitable for an industrial environment with high levels of EMI, for
example for a connection between wiring closets.
Twisted-Pair (TP) Cables (Cord)
The flexibility of the cord cables allows simple installation, for example in a wiring
closet or to connect devices in a control room with low EMI levels.
A maximum of 10 m of twisted-pair cord can be used between two devices. With
structured cabling using two twisted-pair patch cables, this length is maximum for
both patch cables together.
Adapter cables are used to connect devices with a sub-D port to devices with
RJ-45 port.
To convert the RJ-45 interface of a DTE to a 15-pin sub-D interface of the ITP
cabling system, you can use the TP converter cord 15/RJ-45.
Note
Other special cables and special lengths are available on request. You will find a
contact address in Appendix B.
