Ports of ET 200eco PN

Introduction
The ET 200eco PN can diagnose two ports: X01 P1 R and X01 P2 R:
Requirement
• The ports must be configured in HW Config.
• The port diagnostics must be enabled.
Configuring the ports in HW Config
In HW Config, configure the two ports in the "Properties of the ET 200eco PN" dialog:
• "Addresses" tab: Diagnostic address of the respective port.
• "Topology" tab
• "Options" tab:
To enable the port diagnostics, select the following for "Connection" under "Transmission
medium / Duplex": "(Monitor) automatic settings".

4.5 Isochronous real-time communication
Isochronous real-time communication
Synchronized communication protocol for cyclic exchange of IRT data between PROFINET
devices. A reserved bandwidth is available within the send cycle for IRT IO data. The reserved
bandwidth ensures that the IRT data are transmitted at reserved, synchronized intervals while
remaining uninfluenced by another greater network load (for example, TCP/IP
communication or additional realtime communication).
• "High performance" IRT option (not for 6ES7148-6JA00-0AB0 IO-Link Master):
Topological configuration is required (STEP 7 V5.5 or higher).
NOTE
When using the IO controller as a Sync-Master for IRT communication with the "high
performance" IRT option, the following must be observed:
Operate the IO controller as a Sync-Master if you configure the IRT communication with
the "high performance" option.
Otherwise, IRT and RT configured IO devices may fail if the sync master fails.
