PROFINET

• PROFINET IO proxy;
  connection of PROFIBUS DP slaves to PROFINET IO controller with real-time property, according to PROFINET standard

Example configuration: Seamless integration of PROFIBUS nodes into PROFINET via the IE/PB Link PN IO as proxy

Additional functionality for vertical integration

• S7 routing
  • Permits cross-network PG communication, i.e. all S7 stations on Industrial Ethernet or PROFIBUS can be programmed remotely using the programming device.
  • Access can be made to visualization data of S7 stations on the PROFIBUS from HMI stations on the Industrial Ethernet.
• Data record routing (PROFIBUS DP)
  • Using this option, the IE/PB Link PN IO can be used as a router for data records that are forwarded to field devices (DP slaves). SIMATIC PDM (Process Device Manager) is a tool that creates data sets of this type for parameterizing and diagnosing field devices. The configuration of the IE/PB Link PN IO is possible not only via the STEP 7 / TIA Portal but also via the PST (Primary Setup Tool).

The additional functions for vertical integration can also be used in an existing PROFIBUS application without PROFINET for connection to a higher-level Industrial Ethernet.

In this case, the IE/PB Link PN IO is used as an additional DP-Master Class 2 on a PROFIBUS segment for linking to Industrial Ethernet and offers the above functions.

Example configuration: Use of the IE/PB Link PN IO as a default gateway without TIA Portal / STEP 7

Media redundancy (MRP)

Within a PROFINET network with a ring topology, the IE/PB Link PN IO supports the media redundancy protocol MRP as an MRP client

Diagnostics

Extensive diagnostic options are available via STEP 7 or SNMP, including:

• Diagnosis of the assigned PROFIBUS field devices;
  using the IE/PB Link PN IO as a proxy, the connected DP slaves can be diagnosed in the same manner as PROFINET IO devices (even in the user program of the PROFINET IO controller)
• General diagnostics and statistics functions
• Connection diagnostics
• Diagnostic buffer
• Integration into network management systems through the support of SNMP V1 MIB-II

Configuration

STEP 7 V5.5 SP4 or higher or STEP 7 Professional (TIA Portal) V14 Update 1 with an HSP is required for configuring the full functional scope of the IE/PB Link PN IO.

For the IE/PB Link PN IO, STEP 7 automatically generates the necessary parameters, e.g. the addresses and all necessary routing information.

The configuration data for PROFINET IO created with STEP 7 is saved on the IO controller. Attention must however be paid to the memory capacity. The initialization data for the Industrial Ethernet interface is backed up on the C-PLUG (Configuration Plug) swap media. The IE/PB Link PN IO can be swapped in the event of failure without a programming device because the relevant configuration data is saved on the IO controller or on the C-PLUG.

• SINEMA E (license-free TIA Portal for network components)
  The IP and PROFIBUS parameters, as well as the network settings, can also be assigned with SINEMA E (V14 or higher), if the IE/PB LINK PN IO is only to be used as a network transition and not as a PROFINET IO device.
• Primary Setup Tool (PST)
  The IP and PROFIBUS parameters, as well as the network settings, can also be assigned without STEP 7 / TIA Portal, but with the aid of PST (Version 4.3 or higher).
