1. Product description

Update V2.4 of the CP 343-1 (order no. 6GK7343-1EX30-0XE0) provides product improvements and added functions. To be able to use the PNIO added functions you require Step7 V5.5 plus Hardware Support Package HSP 1079.

 

Added functions

·        With the new firmware the CP is now able to run Shared Devices and iDevices as PNIO controller.

·        Support of DHCP Option 12, see entry ID 49588330

For more information on iDevice and Shared Device please see entry ID 44383954

 

Product improvements

·        Faster passiver connection establishment with S/R connections. Depending on the loading of the CP, the latter will be ready again for a renewed connection establishment with the active connection partner within 50 to 500 ms after breaking the previous connection. This applies to the ISO, ISO on TCP and native TCP protocols.

·        Improved S7 routing in conjunction with S7-1200 systems

·        Improved compatibility of the CP in conjunction with RFC2873

·        Improved status indication of faulty modules of PNIO devices from non-Siemens manufacturers on the controller

·        Improved mode change when running the PNIO_SEND and PNIO_RCV blocks in conjunction with high-speed CPUs

·        Improved indication in the NCM diagnosis in conjunction with DHCP and Broadcast/Multicast counters

·        Stopping of the CP with established PBK connections

·        Improved validation of the block parameters in conjunction with IP Config

Remark:

To be able to use the new PNIO feature, the CP must be configured in HW CONFIG  with V2.4. The acceleration of the passive connection establishment does not depend on the configuration. 


Configuration:
To be able to configure all the features of the CP, you require STEP7 V5.5 or higher.
