3) Configure the Generic I/O
connection. Refer to Figure
35.
In the “Connection” portion of
the dialog box, enter the
following information:
Name: In this example, select
Generic I/O.
Size: Because all inverter
data is stored as 16-bit
function codes, change the
data type to “INT array”.
Input: The Input is the
collection of monitor data that
is produced by the interface
card and is received as an input to the PLC. Its structure is defined by the Produced Data
Configuration as described in section 10.2.4. The Input Size must be set to the number of 16-bit
function codes that we wish to receive from the interface card. For the purposes of this example,
we are assuming that the default produced data word configuration, with 2 relevant function codes
(M14 and M09). We therefore set the Input Size to 2 Words.
Output: The Output is the collection of command & configuration data that is sent as an output
from the PLC and consumed by the interface card. Its structure is defined by the Consumed Data
Configuration as described in section 10.2.4. The Output Size must be set to the number of 16-bit
function codes that we wish to send to the interface card. For the purposes of this example, we are
assuming that the default consumed data word configuration, with 2 relevant function codes (S06
and S05). We therefore set the Output Size to 2 Words.
When done, click “OK”.
4) Switch to online mode and download the project to the PLC. Verify that the newly-added inverter is
available and operating corre
ctly by observing any indications shown on the inverter’s icon. When
the inverter’s icon is selected, its status and any available error messages will be displayed in the
area below the project tree. Also confirm that the interface card’s “Network Status” LED should be
solid green, indicating an “online/connected” state.
5) By double-
clicking “Controller Tags” in the project tree, it is possible to view the newly-added tags.
The Interface_Card:I tag allows viewing of the input data, and the Interface_Card:O tag allows
modification of the output data. These tags will be synchronized with the inverter at whatever rate
was established for the module’s RPI. We can directly interact with these tags in order to control
and monitor the inverter.
10.2.11.2 ControlLogix Example: EDS Add-On Profile (AOP) AC/DC Drive Profile
This section will demonstrate how to configure the EtherNet/IP AC/DC drive profile I/O connection.
1)
Complete all steps in section 10.2.11.
2) Locate the interface card in the 1756-
ENBT/A branch under the “I/O
Configuration” in the controller
organizer view. Right click on the
interface
card, choose “Properties”,
and select the “General” tab.
3) Configure the AC/DC Drive Profile
connection. Refer to Figure 36.
In the “Connection” portion of the
dialog box, enter the following
information:
Name: In this example, select
AC/DC Drive Profile 21 71.
Size: Because all inverter data is
stored as 16-bit function codes,
