Raco Manufacturing and Engineering continually makes improvements in the operation and functionality of its products. This addendum describes Catalyst Ethernet communication option that allows the Catalyst to connect directly on the PLC Ethernet networks. This addendum specifically addresses the ModbusTCP and EtherNet/IP protocols.
Are you familiar with the operation of the Catalyst Data Logger/Autodialer yet? Changes to a few, very specific features of the Catalyst are described in this addendum. It is assumed that the reader of this addendum is already familiar with the basic operation and programming method of the Catalyst product and also is familiar with Alarmware software.
01992 will go from 0 to 1 indicating that the communication with the network is impaired and if the Catalyst is programmed to look for this change. A bit flipping from 0 to 1 can report the loss of communication via an alarm to the users.

• Catalyst with Ethernet autodialers don’t work this way. All the different areas are mapped on top of one another. 30001 holds the same value as 40001. Coil 00001 holds the same value as the first bit of 30001 or 40001...
1. At first the PLC and network configuration is explained. 2. Secondly the configuration of the IP-settings and the I/O data of the Catalyst EtherNet/IP are described. The contents describe step by step how a configuration is done. This document assumes the reader is familiar with industrial communication, EtherNet/IP networks.
Before you begin: Ensure that the EDS file (Found on the “Ethernet IP Configuration Tools” CD that was shipped with the Catalyst) is copied to the RSLogix 5000 EDS directory (as indicated by Rockwell Automation Manual). The EDS file insures that the RSLogix controller can identify the RACO Ethernet autodialers in the Ethernet modules and tags.

Click on new module and select the desired Ethernet module, in this case the Ethernet Bridge. This module is the scanner module in the PLC. Figure 4 Selecting the type of module.

8.2. EtherNet/IP network configuration The second step is to configure the EtherNet/IP network and adding the RACO Catalyst EtherNet/IP module to the configuration in the PLC. Begin with setting the program in “Offline” mode. Then right click on the EtherNet/IP Bridge in the I/O configuration, and select “New Module”.

Ethernet”. This name will create a tag in RSLogix 5000, which can be used to access the memory location in the PLCs memory where the data for the Catalyst module will be stored. A description can also be added, but that is optional.

The size of the input connection and the output connection shall correspond to the size that we have configured the Catalyst module for. In our case we are using 32 8-bit values of input and output data, so that is the size that we enter. 32 in this case stands for 32 instances of 8 bits. If we had been using Data-INT or Data-DINT, we would have to recalculate the size to match the data type, so Data- INT would have been 16 16-bit values, and Data-DINT would have been 8 32-bit values.
50 ms to reduce the network load. Make sure that “Inhibit Module” isn’t checked. After this, press finish. Now the Catalyst has been added to the I/O configuration in RSLogix 5000. The main screen will look as follows.

“Download”. The configuration will now be downloaded to the PLC. Figure 14 Downloading the configuration to the PLC. If there are any errors, a warning triangle will be present on the Catalyst in the I/O configuration listing. Double click the module to view any error that is reported.

IP-settings as seen below. Note: The RACO IPConfig tool is able to locate all the RACO Ethernet Autodialers in the network. There is no need to have the Autodialers in the same subnet to be discovered.
When connected to ControlLogix controller, it is possible to access the data exchanged by the ControlLogix 5000 and the Catalyst module. By writing data to the tags the communication between the PLC and the Catalyst it is possible to ensure that the corresponding data bytes have changed on the Modbus RTU side of the network.
11. Quick Start 1) Set up Catalyst: (Note that although some Catalyst parameters can be configured with the front panel keys, Catalyst Ethernet will need to be configured with Alarmware) Install Alarmware Connect to the Alarmware port of the Catalyst Add a new RTU within Alarmware, using the corresponding model number Select that RTU and click the “Connect COM Port”...

When the front panel lights begin to step through the numbers sequentially, release the short and let the unit continue until it is finishes booting. Saved: 2014-06-18 RACO Manufacturing and Page 21 (21) Engineering Filename: Catalyst Ethernet Addendum 1 1 V1_5 released...
