    Firmware update for CM 1241


    DESCRIPTION:

    When updating the operating system, always update to the latest version available for the product and its respective article number. The previous versions of the operating system are only intended as backup to allow a downgrade to the original version. Until now this is not known to have been necessary in any case.

    The respective latest version of a CM operating system is valid for all versions of that article number.

     

    Required user action: 

    You can install the firmware update from the Web server, the online diagnostic functions of TIA portal, or by making a SIMATIC memory card using the Siemens customer support Web site that contains the firmware update. The S7-1200 System Manual documents these methods.


     Overview of article numbers and firmware versions of the CM1241:
     Note: The software is subject to export restrictions, a download is only available to registered users.

     Update V2.2.0

    The Firmware update V2.2.0 for S7-1200 CM 1241 supports  by using an S7-1200 CPU with firmware version 4.2 or later

    • the 3964R protocol and 
    • enables time synchronization within central rack for left side modules (Ethernet and tele control CP's).  


     Update V2.1.0

    The S7-1200 CM 1241 firmware update V2.1.0 is necessary for the CM 1241 communication modules to support the new Point-to-Point, Modbus RTU, and USS library instructions that the S7-1200 V4.1 Programmable Controller System Manual describes.

    Without the V2.1.0 firmware update, the CM 1241 communication modules support only the legacy versions of these communication instructions.  


     Update V2.0.3

    The S7-1200 CM 1241 firmware update V2.0.3 provides general robustness improvement in the operational behavior of the communication module CM 1241.
