3.7 Measurement on the copper cabling
This chapter shows how the PROFINET copper cabling can be tested.
Several measuring devices from the various performance classes are also
mentioned by way of example. A distinction is made between:
• simple cable tester (verication)
• function tester (qualication)
• acceptance tester (certication)
3.7.1 Cable testers
Cable testers were developed to provide an easy way of testing Ethernet
installations. The devices available on the market
offer different functions, scopes and in particular different forms of operation.
They cannot therefore be described here in detail.
