1 Introduction
This document provides step by step instructions on how to establish data exchange
between a Siemens S7-300 PLC and an Allen-Bradley ControlLogix PLC, using a Softing
echochange protocol converter.
General description of the presented example:
Both PLCs and the echochange are in the same network
The S7-300 controls the flow of communications, using PUT and GET functions
The PUT function is used to write data from a S7-300 data block (Data_to_CLX, 1
byte) onto a ControlLogix tag (Data_from_S7)
The GET function is used to read data from a ControlLogix tag (Data_to_S7, integer
array of 50 elements) and store it onto an S7-300 data block (Data_from_CLX)
Software used:
Siemens SIMATIC Step 7 V5.4 SP5
Allen-Bradley RSLogix 5000 V20.01.00 (CPR 9 SR 5)
Allen-Bradley RSLinx Classic Lite V2.59.02 (CPR 9 SR 5)
Softing NetCon echo V4.33

2 RSLogix 5000- create tags to send and receive data
1. Create a tag to receive data from the S7-300 PLC. In this example we will create a
SINT tag (short integer, 1 byte).
a. In the Controller Organizer section, right-click on Controller Tags and then
click on New Tag….
b. Enter a tag name, select data type SINT and click Create.

2. Use the previous method to create a tag for the S7-300 to read. We will create an INT
(integer) array with 50 elements.
3. This is how the new tags should look in the Controller Tags table:
4. Download the project to the ControlLogix device.

3 NetCon echo – echochange network settings
1. Configure the network settings of the echochange port to be used. We will use port 1
(Eth 1).
a. Click on Station Own Station 1.
b. As a minimum, the IP address and subnet mask are required. DNS and Router
addresses may be necessary in some cases.
