PowerTRAC Calculated Data Screens
After the Status Inputs, the HHM displays the block's calculated data values. Lines 2 and 3 identify the data being displayed and show its present value. In the example below, voltage A to N is 117 volts.

PowerTRAC Extra Calculated Data (LPIO) Screens
If the PowerTRAC block is version 2.3 or later, the
The block may or may not automatically provide this data to the host, depending on the block's revision level and configuration. A CPU can use datagrams to read the data.

On these screens, the top line shows the serial bus address of the block and the relative data word being displayed. For example, the screen above shows the 20th input word (Fundamental VARs for phase A). This area of line 1 blinks as a reminder that the numbers shown are not reference addresses.
PowerTRAC Control Outputs Screens
Finally, the HHM displays 16 screens showing the states of individual Control Outputs (datagram handshaking bits). If you use the F1 ( > ) key to reach the Control Outputs, notice that there are several unused references following the Extra Calculated Data data. You can use F2 (ref) to go directly to output 1. You may need to toggle the memory type to %Q (or O, depending on the host CPU setup of the HHM).

Forcing PowerTRAC Data
(The HHM's circuit forcing capability must be enabled to perform this function). Display the data you want to force. Press F3 (force).
For bit data, the HHM displays:
m o n o n o f f r e l e s
Press F2 (on) or F3 (off). To release the force, press F3 (reles).
For word data, the HHM displays:

Press F2 (chng). Enter the force value, then press F3 (entr). To release the force, press F4 (release).
Diagnostics
The PowerTRAC block does not report circuit faults. If you use the F4 (diag) key from the Monitor/Control Reference screen, the message NO FAULTSwill appear.
