No. Both PROFINET and EtherNet/IP have defined their own specific redundancy protocols. However PRP and HSR can nevertheless be applied to PROFINET and EtherNet/IP. It is most likely that PRP and HSR in the future may become common in these environments. Hirschmann devices support the simultaneous use of both PRP and HSR to create a zero packet loss network with the highest level of redundancy.

It depends on the different focus of network design: PRP is a better solution, if high bandwidth is required. When customers do not require maximum bandwidth, HSR is a good choice and is also cheaper to install than PRP.
However a major advantage of PRP is the ability to mitigate multiple network failures - in other words, when zero packet loss is required. In contrast, HSR covers only one failure. Nowadays, the communication network inside an automotive manufacturing mainly works over a ring network topology, therefore HSR may be recommended. If zero packet loss is not required, PRP with recovery times of 10ms or 30ms is  interesting for customers.

The communications infrastructure comprises switches, cables and connectors. Network components and media are the cause of over 70% of all network faults, – so it is clearly that the hardware is very important to the network.

Therefore the costs of high performance components are minimal compared to the expenses of a network failure, where downtime expenditures can be measured in thousands of €uros a second. If a commercial Ethernet switch or cabling system fails in an industrial environment, the real cost to the manufacturer is typically much more than just the replacement cost of the components.

high quality industrial cabling solutions from Belden help you to increase your profitability for the lifetime of the production line.

LioN-R modules for PROFINET enable cost effective solutions whenever you need to connect sensors and actuators to controllers. They owe their high functional reliability to the galvanic isolation between sensors / actuators and PROFINET, and to their simple diagnostics concept, both ensuring maximum machine operating times. Because the modules come with an integrated 2-port switch, you can even implement line topologies without needing additional switches, so also saving investment costs. The standardized M12 connection technology brings further benefits.

In comparison with parallel wiring, the efforts for all types of tasks are further reduced – from planning, installation and maintenance right through to warehousing. What’s more, M12 connection technology is a future-proof investment. In other words, you can extend your plant and equipment quickly and easily at any time.

Combined with the “easy diagnostics” concept, the galvanic isolation between sensors/actuators and PROFINET brings maximum availability of systems and machines

• Short circuit-proof outputs contribute to maximum functional reliability
• The “fail-safe” function ensures reliable operation as well as safe switch-off in case of faults
• Support for RT and IRT real-time standards
• PNO-certification and UL approval
• EtherNet/IP models available: secure EtherNet/IP connection of sensors and actuators to controllers
