CompactLogix Example

Creating Ladder Logic Using the Logix Designer Generic Profile (all
versions)

Adapter Parameter Settings for CompactLogix Controller Example

These adapter settings were used for example ladder logic program in this section.

Controller Tags

When you add the adapter and drive to the I/O configuration (

Chapter 4

), Logix

Designer automatically creates generic (non-descriptive) controller tags. In this
example program, the following controller tags are used.

CompactLogix Controller Tags for Drive Generic Profile Ladder Logic Program Example

You can expand the Output and Input tags to reveal the output and input
configuration (see

CompactLogix Controller Tags for Drive Generic Profile

Ladder Logic Program Example on page 51

). For this example, the Input tag

requires three 32-bit words of data and the Output tag requires three 32-bit
words of data. This corresponds to six 16-bit words of data for input and six 16-
bit words of data for output because the 1769-SDN is a 32-bit device.

TIP

The PowerFlex 525 drive supports up to three control functions and three
Reference functions. There are several parameters in the drive that will
override the start source and speed reference command if enabled. For details
on these parameters, see the PowerFlex 525 drive’s user manual, publication

520-UM001

.

The Host parameters [Opt Data Out 1...4] are inputs into the drive that come
from controller outputs (data to write a drive parameter). The Host parameters
[Opt Data In 1...4] are outputs from the drive that go to controller inputs (data
to read a drive parameter).
