PLC Message Registers
The EZ-220, EZ-220V, EZ-220L, EZ-420, EZ-220P, and EZ-220PV panels have 2
or 4 lines of PLC Message display. Each message line references a user-defi ned
register in the PLC. The registers are assigned using the EZSeries Set Point
Display Text Panel Programming Software. The panel monitors each register
for a value (message number) and displays the message associated with the
value (i.e., a value of 3 displays message 3).
Embedded Data Registers
Each message can have up to three embedded data values, DATA 1, DATA 2,
and DATA 3. Embedded data registers are user-defi ned.
DATA 1 (16-Bit Register, READ/WRITE )
This is a PLC register that contains the fi rst of three possible embedded data
values on a line for the message displayed. DATA 1 can be set as a READ/
WRITE Register allowing the operator to change a data value. It can also be set
to READ ONLY. This is the only data value that has this option.
