Figure 3.2 shows the basic measurement setup for simple cable testing of
PROFINET copper cabling. Basically it’s a case of testing an electrical connection,
i.e. testing for connection and/or short-circuit and impermissible split pairs. The
testers do not check cable parameters or whether data packets can be transferred
via the cable. These testers can be used during installation to check cables for
connection/short-circuit and to check for correct contact assignment on the plug-
in connector.
The cable tester shown here is a standard tester for the Ethernet.
Special testers are not used for PROFINET.
When using a cable tester on PROFINET networks which have
been set up with PROFINET copper cables (100BaseTX with 2 x 2
wires), the cable tester only shows a connection for the individual
cables 1, 2, 3, 6 and shielding (G). With PROFINET, note that the
pairs of wires don't have to be crossed because the active network
components perform auto crossing.
