SLC 500 Controller Example Response Data for DEM Read Single Message
In this message example, we use the data table address in Figure 6.37 to
store the response value (0.13 amps) that was read from drive parameter 003
- [Output Current].
In this example, Output Current is a 32-bit parameter. For PowerFlex 700S
or PowerFlex 750-Series drives, Output Current is a floating point number.
To manipulate REAL data into a proper Float tag, see the
‘Communications’ section in Chapter 1 of the PowerFlex 700S AC Drives
Phase II Control Reference Manual, publication PFLEX-RM003.

SLC 500 Controller Example DEM Instruction Ladder Logic Program to Write a
Single Parameter
A Generic Set Attribute Single message is used to write to a single
parameter. This write message example writes a value to parameter 140 -
[Accel Time 1] in a PowerFlex 7-Class drive.
