(1) Non-volatile SRAM does not require battery power for data backup. The internal battery in the HMI SCU is only requeried for Real Time Clock (RTC). |
Vijeo Designer alarm data and variable logging is automatically stored in non-volatile SRAM in a first-in-last-out format. The number of datum stored in the SRAM is user-defined. This data from SRAM can also be optionally backed up in removable media when a user-defined number of new data points is logged and/or can also be triggered by an action.
Variations in operating conditions (i.e. varying ambient temperature) can cause a clock shift. (Refer to the topic Real Time Clock for details.)
