The module properties dialog box will open (refer to Figure 43). Enter a Name which will allow
easy identification of the inverter on the network (the tags created in RSLogix 5000 will be derived
from this Name). Because all inverter data is stored as 16-bit parameters, change the “Comm
Format” selection to “Data-INT”. Enter the IP address of the targeted interface card.
Figure 43: Interface Card Module Properties
In the “Connection Parameters” portion of the dialog box, enter the following information:
Input:
The Input Assembly 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 9.2.4. The Input Assembly Instance must be set to 150 when connecting to
the generic I/O assembly instances (or 70/71 when using the ODVA AC/DC drive profile), and the
size must be set to the number of 16-bit parameters 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 two relevant parameters (01.04 and 01.01). We therefore set the Input Size to
2.
Output:
The Output Assembly 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 9.2.4. The Output Assembly Instance must be set to
100 when connecting to the generic I/O assembly instances (or 20/21 when using the ODVA
AC/DC drive profile), and the size must be set to the number of 16-bit parameters 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 two relevant parameters (00.02 and 00.04). We therefore
set the Output Size to 2.
