8. PROFINET IO switch
The TPS-1 contains a PROFINET switch with 2 external ports. Thus, PNIO devices can be connected directly to each other without the need for
external switching devices (line topology).
Figure 8-1: Network topologies with the TPS-1
All necessary PROFINET protocols are implemented (LLDP, PTCP, MRP, etc.). Additionally, the TPS-1 features 2 integrated PHY devices (IEEE
802.3, IEEE802.3u, ANSI X3.263-1995 and ISO/IEC9314).
Each port of the integrated PROFINET switch has its own MAC address. The MAC addresses are provided by the device manufacturer and stored in
the Boot-Flash of the TPS-1.
The implemented hardware processes support all PROFINET communication channels (NRT, RT and IRT). The Ethernet standards 100BASE-TX and
100BASE-FX are supported.
Additionally, the PHYs support the following features:
• Auto-Negotiation,
• Auto-Crossing
• Auto-Polarity
In order to indicate network status and traffic, the TPS-1 provides respective signaling outputs:
