Monitor/Control Reference Displays for a PowerTRAC Block
For a PowerTRAC block, the Monitor/Control
Reference function displays:
16 screens, each showing the state of one Status
Input. This information is more easily dis-
played with the Monitor Block function,which
shows all 16 Status Inputs on one screen. See
page 5-7.
Individual labelled displays of the block’s current
calculated data values. For PowerTRAC block
version 2.3 or later, this includes the “low-priority
I/O”screens described on the next page.
16 screens, each showing the state of one of the
block’s Control Outputs. Control outputs are
also more easily displayed using Monitor Block.

Selecting a Memory Type or Address
To select a specific data item, you can enter its
memory type and/or address. Press F2 (ref). This
screen appears:
M N T R __
t g l c h n g e n t r
1. Enter the reference number and press F3 (entr).
If the HHM is set up for a PLC host, I/O refer-
ences increment by 16 and word(register) refer-
ences increment by 1. For a PLC host, both I/O
and word references start at the first reference
assigned to the block. If the HHM is set up for
a PCIM/QBIM/GENI host, references begin at 1
and increment by 1.
2. The memory type blinks on the screen. To
change the memory type, use the F2 (tgl) key.
3. Press F3 (entr) to display the information.
