Power Fail Status Information (9 Registers Defined)
If the TPU2000 or TPU2000R loses power, the unit has the capability to sense power is being lost. During this
shutdown time, the unit stores the timestamp of power fail occurrence. The storage format is shown in Table 5-
16.

Fast Status (2 Registers Defined)
Fast Status is available for an operator interface to determine the device queried. The Division Code for the
TPU2000/2000R is 1A HEX. The product ID for the TPU2000/2000R is 0E HEX.
One should also notice that the reporting of a new operation record is reported here in word 40170 in bit position
9. The bit is reset whenever the word is accessed via a network read.
