RSLogix 500 Configuration
Platforms supported by the RSLogix 500 software package require Message Instructions to communicate
with the SD17060E. This section uses a MicroLogix 1100 to describe how to configure these instructions.
Two instructions are required to transfer data between the PLC and the SD17060E. One instruction reads
data from the SD17060E and the other writes data to the drive. The following table gives the required
attributes for the instructions.
Table 6.1 Message Instruction Attributes
Using Message Instructions in a MicroLogix 1100 PLC
Only RSLogix 500 version 8.0 or above can be used to configure Message Instructions to
communicate with an Ethernet IP device.
1) Create four new data files.
h
An Integer file to contain the data from the SD17060E. This file must have enough elements to
contain all of the data read from the drive.
h
An Integer file to contain the data sent to the SD17060E. This file must be large enough to con-
tain all of the data written to the drive.
h
A Message (MG) data file. This file must have at least two elements, one to control the Read
Operation and one to control the Write Operation.
h
An Extended Routing Information (RIX) data file. This file is used to store information used by
the Message Instructions. This file must have at least two elements, one for the Read Operation
and one for the Write Operation.
2) Add the Message Instruction(s) to your Ladder Logic. The following rungs show how you can
alternately read data from and write data to your SD17060E.
