Quick Setup Guide for the Ethernet IP Gateway

Hardware Setup:

The Ethernet IP Controllere should be connected to the network via the RJ45 connection. This is explained in detail in the Controllere Ethernet manual. For direct connection from the PC to the Controllere requires the use of a cross over

cable with crossed data wires. For connections via a Hub, Router, and Switch, a straight Ethernet cable should be

used.

Example Configuration

This procedure will configure the system with memory allocations for 1 Master with up to 31 A slaves and 31 B slaves. The communication card used inside the PLC configuration in our example is the 1756-ENBT/A 10/100 Mbps Ethernet Bridge, Twisted-pair media from Allen Bradley. The Controllere comes defaulted with an IP Address of 192.168.10.17. Instructions on how to add/change these and other parameters can be found in the User Manual.

Set Gateway Configuration

1. From the Controllere display, go to Menu / Fieldbus Setup. You will be at a screen to view/change the IP Address. Press the ESC button once to enter the Subnet Mask screen. Press the ESC again to enter the Mac ID screen. Press the NEXT button to begin entering the Module byte lengths.

2. Enter the following byte valuesModule 1 Digital Inputs Master 1A 16 byteModule 2 Digital Outputs Master 1A 16 byteModule 3 Digital Inputs Master 2A 16 byteModule 4 Digital Outputs Master 2A 16 byteModule 5 Digital Inputs Master 1B 16 byteModule 6 Digital Outputs Master 1B 16 byteModule 7 Digital Inputs Master 2B 16 byteModule 8 Digital Outputs Master 2B 16 byteModule 18 FieldBus Diag. Data 2 (Both masters 26 words)

3. Modules 9 – 17, 19 need to be set to 0.

4. These settings are permanently stored by exiting the menu function Fieldbus Setup. The changed settings will take effect a few seconds after leaving the menu function Fieldbus Setup.

Set Configuration in RS Logix5000

1. Open RS Logix5000, enter either a new or existing project and set the program to offline mode.

2. Add a new module for the AS-i Ethernet IP controllere to the configuration in the PLC. Do this by right clicking the Ethernet/IP device 1756-ENBT/A in the I/O configuration, and select from the appearing context menu “New Module...”.

3. In the new window select “Generic Ethernet module” and press “OK”.

4. In the next window enter the following values. Custom values for Name and Description will not disturb the configuration.

5. After all adjustments are done click on the button “Finish >>” to create the module.

6. Connect the PC to the Controllogix, turn the key switch to PROG and download the new configuration.

7. Turn the Controllogix key to RUN, and you will find the new module “ASI Gateway” inside the Controller Tags.

8. The following shows the default mapping of the slave bits into the above I/O table.Master 1 A-Slaves
