Control is processed in that Registers 41456 and 41457 are "ANDED" together. If the resultant logical operation
is completed with the result being a "1" in that bit location, the control function is executed.
TPU2000/TPU2000R offers immediate control. No buffering of commands is attempted.

Oscillographic Data Storage (Version 1.5 and Greater TPU2000R Only)

The TPU2000R has the capability of accepting an option of OSCILLOGRAPHICS (Part Number 588 XXXXX –
X1XXX [X = Don't Care]). The total storage buffer capacity for the TPU2000R is 64 cycles of waveform data,
which consists of four input currents (one per phase and neutral), and three input voltages. A user may configure
the TPU2000R to capture a single or multiple events of waveform capture.
