Monitor/Control Reference Displays for a PowerTRAC Block
For a PowerTRAC block, the Monitor/Control Reference function displays:
H16 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
HIndividual labelled displays of the block's current calculated data values. For PowerTRAC block version 2.3 or later, this includes the
H16 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:

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.
