frequency noise influence.
Wiring
• Do not install cables together with the main circuit lines or power cables.
• Place cables in a duct.
Switching hub
Use switching hubs that support the transmission speed of communication when using switching hubs in PROFINET.
When the industrial managed switch (NZ2MHG-T8F2) is used, use the industrial managed switch (NZ2MHG-T8F2) with the
production information (first six digits) of 7104AV or later.
