Monitor Block Display for a PowerTRACBlock
If the active device is a PowerTRAC block, the HHM's Monitor Block function displays the following screens:
HOne screen showing the states of all of the block's Status Inputs.
HIndividual screens showing the block's current calculated data values. In the Monitor Block function, these values are NOT labelled. It is easier to display this information using the Monitor/Control Reference function (F2), be- cause those displays are labelled.
HOne screen showing the states of all of the block's Control Outputs.
On each of these screens, you can press F1 ( > ) to display next screen, or press F2 (ref) and enter a reference location to display a specific screen. For a sequential list of the PowerTRAC block data, see page
Bit 15 = 1 means the overcurrent event indicated by bit 4 occurred on the auxiliary current line.
Bit 16 = 1 indicates an internal calculation has re- sulted in an
Calculated Data
After the Status Inputs, the HHM displays the block's calculated data. If the PowerTRAC Block is version 2.3 or later, this includes the additional

Status Inputs
The Monitor Block function first displays the PowerTRAC block's Status Inputs:

O O O 1 1 O O O O O O 1 O O O O
>r e f
Line 2 indicates each of the 16 possible bit locations for status data. Lin e3 shows the current states of all inputs.
Bits 1 ± 3 indicate the status of table data transfer, for datagram communications.
Bit 4 = 1 indicates the block has captured an over- current event.
Bit 5 should always be 1, indicating that the block's
Bit 12 = 1 means the overcurrent event indicated by bit 4 occurred on phase A.
Bit 13 = 1 means the overcurrent event indicated by bit 4 occurred on phase B.
Bit 14 = 1 means the overcurrent event indicated by bit 4 occurred on phase C.
Control Outputs
After the calculated data screens, the HHM's Monitor Block function displays the PowerTRAC block's Control Outputs. You can also display this data by using the F2 (ref) key to select output 1. You may need to toggle (F2) the memory type.

Line 2 indicates each of the 16 possible bit locations for Control Outputs. Line 3 shows the current state of each Control Outputs. These outputs are communications handshaking bits, sent from the CPU to the block for certain datagram communications. Information about these outputs is in the PowerTRAC Block User's Manual.
