About the FDR Service
The Ethernet communications module includes a fast device replacement (FDR) server. That server provides operating parameter settings to replacement Ethernet devices that are equipped with FDR client functionality.
Any networked Ethernet device that is equipped with FDR client functionality can subscribe to the Ethernet communications module’s FDR service. The module can store up to 1 MB of FDR client operating parameter files. When this file storage capacity is reached, the module cannot store any additional client FDR files.
The Ethernet communications module can store FDR client files for up to 128 devices, depending on the size of each stored file. For example, if the size of each FDR client file is small (not more than 8 KB) the module could store up to the maximum of 128 parameter files.
In an M580 Hot Standby system, the PRM files managed by the FDR server in both modules are synchronized when the applications in both PACs are the same. Refer to the discussion of FDR in Hot Standby systems in the Modicon M580 Hot Standby System Planning Guide for Frequently Used Architectures.
Por lo tanto, como máximo se pueden configurar 128 dispositivos. La suma de todos sus ficheros de configuración no pueden superar 1MB.
