  • 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.
