It is located under the communication card module.This board provides non-volatile (NV) application configuration backup memory and clocktime management.Setting the Real Time Clock (RTC)There are three ways to set the Real Time Clock parameters:1. The Monitoring User Interface with the following pathPRG R Real Time Clock R Date & Time2. Using a Modbus or Modbus TCP master and writing to the RTC parameters. Referto the Modbus register map in Appendix D.The RTC parameters begin with Modbus register 4000. Each individual time/clockparameter can be written to set the RTC, or a single parameter (register 4010) canbe written with a value containing the “Real Time clock in Seconds from the UNIXEpoch”. This is a 32 bit value.3. Using the Power Xpert inControl Software Tool and selecting a single button to setall RTC parameters from the RTC parameters on the computer running thesoftware.This is the most straight forward way to set the RTC. Connect with the C445 viaone of the supported protocols and ports and perform the following steps:(1) Once online with the C445, select the Real Time Clock icon as shown below.The Real Time Clock window will open as below.4. Select the proper time zone.
