10.2.1
In the case of system failure (IBV_L, IBV_H, AC_FAIL, RES_N), the data for 10 monitoring cycles immediately
preceding the system shutdown is copied into the non-volatile ring buffer memory. After the system shutdown, the
ring buffer can be accessed either via the GUI or directly via the I
data will be stored in the ring buffer until the next time the system is turned on therefore allowing for remote
diagnostics and troubleshooting. Once the data is written into the ring buffer it cannot be overwritten until the DPM
supply voltage is recycled or the ring buffer is cleared in GUI as shown in Figure 11 or directly via the I
using high and low level commands.
Contents of the ring buffer can be displayed in the GUI IBS Monitoring Window shown in Figure 12 or can be read
directly via the I
