FRAM/RTC + 256 KB Storage for Nano or FMD PLCs
A lithium battery-backed Real Time Clock (RTC) and non volatile FRAM memory block for the Nano-10, FMD88-10 or FMD1616-10 PLCs . Athough there is an internal RTC on the PLC's, this clock will loses its content when the PLC is powered OFF and you will need to set the RTC when the PLC is powered ON again. On the FRAMRTC the clock is maintained by the 3V lithium cell battery and will run continuously. The PLC CPU automatically detects the presence of FRAMRTC and will load its internal RTC with the data from FRAMRTC upon power ON. This unit comes with a 256 KB data storage to expand the capabilities of web server interface.
