The PROFINET communication interface modules plug into the PROFINET I/O terminal unit. When properly plugged-in, they are secured with two mechanical locks. All the electrical connections are established via the PROFINET I/O terminal unit, which allows removal and replacement of the communication interface modules without disturbing the wiring at the PROFINET I/O terminal unit.

The PROFINET I/O terminal unit TU520-ETH are specifically designed for use with AC500/S500 PROFINET communication interface modules (e. g. CI504-PNIO, CI506-PNIO).

The terminals 1.0, 2.0, 3.0, 1.1, 2.1 and 3.1 are electrically interconnected within the PROFINET I/O terminal unit and always always the same assignment, irrespective of the inserted PROFINET communication interface module:

  • Terminals 1.0, 2.0 and 3.0: process supply voltage UP = +24 VDC
  • Terminals 1.0, 2.1 and 3.1: process supply voltage ZP = 0 V

The assignment of the bus system terminals depends on the inserted PROFINET communication interface module (see ETHERNET communication interface modules overview).

Attention

:strong:Risk of corrosion!

Unused connectors and slots may corrode if XC devices are used in salt-mist environments.

Protect unused connectors and slots with TA535 protective caps for XC devices TA535: Protective Caps TA535 for XC Devices TA535 - Protective Caps for XC Devices.
