1. INTRODUCTION

The information provided in this document helps the user setup and test the Catalyst

Ethernet Module. The main purpose of connecting to the Ethernet network is to

access the PLC data natively instead of connecting on other external network bridges.

This addendum is in effect a new section to the Industrial Networks section of the

manual (Section 1.9.1 in the main Catalyst Owner’s Manual). Therefore, the content

of this addendum covers all the requirements of connecting to the Ethernet network,

which also includes all testing and diagnostics.

A. Prerequisites

Prior to starting this process, please ensure:

•The user is familiar with the basic operation and programming method of the

Catalyst product and the Ethernet-specific software. Only the Ethernet-specific

features of the Catalyst are described in this addendum.

•The Catalyst is setup and functioning in accordance with the manual.

•The user has basic familiarity with Windows PCs and networking.

•The Catalyst and PC are connected to a LAN and have the capability to

communicate via TCP.

The user has the appropriate IP configuration information for these devices.

B. Overview

Adding a Catalyst to your PLC system is a simple 3-step process:

1. Connect and configure the Catalyst to your specific network (Section 2.A)

2. Assign a Catalyst alarm channel to the System Network Address (SNA)

(Section 2.D)

3. Testing that the Catalyst responds to Ethernet commands. This is an optional

procedure that requires ComTest Pro a free third-party software program

(Section 3)

2. Catalyst Configuration

This section will cover setting up the Catalyst Ethernet Module for your network and

assigning alarm channels to the desired SNAs (System Net Addresses).

A. Configuring the Catalyst Ethernet Module IP Settings

The Catalyst’s Ethernet Module’s IP settings must be configured in order to connect to

the network. The current Ethernet Module’s IP address must initially be determined

and then configured to correctly match your network setup.

Determine and configure the IP Address

1. Connect a standard RJ-45 Ethernet cable to the Ethernet Module. This should

be on a network that is accessible to the PC and the PLC to be monitored.

4. If more than one Catalyst is found, you may need to temporarily disconnect one

or more of them to determine which the correct one is. Alternatively, you can

compare the MAC address printed on the Ethernet Module to the displayed

MAC Address.

5. Double-Click on the line containing the IP address of the Catalyst that you

want to configure. The configuration window will appear.

6. It is highly recommended that the Catalyst and PLC be assigned static IP

addresses to avoid loss of connectivity if the DHCP server assigns a different IP

than the system was configured to use.

7. For a static IP, enter the IP address, Subnet mask, and Default gateway

provided by your IT Department. You can leave the DNS entries blank.

8. For a Dynamic IP (DHCP) select the DHCP On option button. You do not have

to enter the remaining fields.

9. Close the configuration window and Exit the IPConfig tool.

CAUTION: If DHCP is left on, the PLC can lose connection with the Catalyst if the

DHCP server changes the Catalyst’s IP settings.

B. Test the Catalyst Ethernet Module connectivity

1. Open a browser on the PC and enter in the Catalyst’s IP in the address bar.

The browser should display a page similar to this one. If it does not, or if the

Saved: 2015-08-03

displayed configuration is incorrect, then there is a problem that needs to be

rectified before the Catalyst will be able to connect.

2. The Catalyst Ethernet Module is now configured and ready to receive data from

other devices on the network.

C. Catalyst Data Register SNA Addressing

It is helpful to have a basic understanding of the Catalyst addressing system to

configure alarms successfully.

What is an SNA?

The PLC sends alarm data to the Catalyst via the Catalyst Ethernet Module’s IP

address in conjunction with a unique SNA (System Net Address) address. The SNA

consists of a Network number, a Node number, and an address on that node. SNA

1*2*00001 would identify Network 1, Node 2, Address 00001. For the Catalyst

Ethernet Module, the Network is always 1 and the Node is always 2: 1*2*xxxxx.

The Catalyst can read 1968 addresses in the range from 1*2*00001 to 1*2*01968.

Each of those addresses corresponds to one bit (coil). Any of these addresses can be

assigned to any Catalyst alarm channel. This also can be represented as a range of

123 16-bit analog addresses in the range of 1*2*40001 to 1*2*40123. The relationship

between discrete and analog addressing is described in the following sections.

SNA Data Types

The Catalyst determines if the SNA represents discrete or analog data by the first digit

of the SNA. If the first digit is a 0 (1*2*00001) then the data is a single discrete bit.

This can be considered as the equivalent of a PLC coil. If the first digit is a 4

(1*2*40001) then the data is a 16-bit integer register that represents an analog

reading like pressure or temperature.

SNA Discrete and Analog Register Addressing

This SNA numbering convention is just two different ways of looking at the same data

registers. The 16-bit register at 1*2*40001 is composed of the 16 single bit registers

1*2*00001 to 1*2*00016. In other words, SNA 1*2*00001 refers to a bit in the 16-bit

mapping is covered in Section 2.C.e.

For simplicity in avoiding conflicts, we suggest that you assign the Discrete channels

Saved: 2015-08-03

Filename:

Catalyst EtherNet Option Setup R5 V01.docx RACO Manufacturing and Engineering

to the lower registers plus some margin for additions and then assign the Analog

channels above that range.

To allocate space for 50 Discrete alarms:Each Analog register requires 16-bits. 50

divided by 16 = 3.125 so that would make the first 4 Analog registers unavailable. The

first Analog SNA free would be 1*2*40005 as well as all the registers above that.

To determine the exact bits used by an Analog channel: The first bit is found by

this equation {(Analog SNA -40001)* 16} +1. Analog SNA 1*2*40005 would be

{(40005-40001)* 16} +1 = 65. The Discrete bits used would be SNA 1*2*00065 and

the next 15, ending at 1*2*00080.

SNA Discrete to Analog Register Bit Position Mapping

Each Analog register consists of 16 individual bits, numbered from 0 15. There are

numerous ways that that the single bit Discrete register addresses can be mapped to

these bit positions and can vary with different PLCs. We will discuss the common

options here. If these do not match your scenario, please contact Technical Support

and we will gladly assist you.

Determining the mapping

Numerous standards and variables can make determining the end-to-end mapping

that your system uses. Rather than going through the process of determining the

exact mapping that your system uses, it can be faster to do a quick test to locate the

correct mapping to find a specific bit. This will also verify that the system is working

properly.

1. Verify the correct Analog Register address:Monitor the status of the bit in

question. Write FFFF-hex to the Analog register that you suspect contains that

bit. The bit in question should be set to 1 as FFFF-hex will set all the bits in that

addressing is incorrect, or there are other issues that must be resolved before

continuing. A common problem is that the addressing is off by one, so try the

Analog registers that are immediately before and after it.

2. Locate the correct byte: Sequentially write F000, 0F00, 00F0, and 000F to the

Analog register. Note which value turns the bit on. The bit will be set to 1 when

F (1111) is written the byte that contains it.

3. Locate the correct bit: Sequentially write 1, 2, 4, and 8 to the byte positon that

turned the bit on in step 2. If the bit came on when you wrote 0F00, write 0800,

0400, 0200, and 0100 to the register. The bit in question will turn on. Converting

the number to binary will show the correct bit. If 0400 turned on the bit, then the

bit location would be where the 1 occurs in the binary representation: 0000

0100 0000 0000

RACO Bit Addressing

RACO Catalyst bit addressing for Modbus TCP and EtherNet/IP both conform to the

Modbus standard order for consistency. The Discrete registers (bits) are addressed

sequentially starting at the most significant bit position (little endian order)

Ethernet_Fail Bit

The Catalyst Ethernet Module constantly monitors the status of the Ethernet

connection. If the connection is good (the Ethernet cable is connected and the

Catalyst is actively receiving data from the PLC) the adapter will set address

1*2*01992 to 0. If the Catalyst is not connected or is not receiving data, the adapter

will set address 1*2*01992 to 1 indicating a failure in the Ethernet connectivity.

We recommend that the first SNA that you configure is the Ethernet_Fail bit so that

you can easily verify that the connection is good for the remainder of the setup. It is

usually set to the last alarm channel in your Catalyst to leave the lower channels open

for standard alarms, e.g. Ch. 56 in a 56 channel Catalyst.

D. Assigning a SNA to a Channel

The user must assign an address to a channel for each register he wants to monitor.

They must also specify the alarm condition when configuring each channel.

The process will only be briefly reviewed here as it is covered in detail in the Catalyst

manual.

Assign and Configure a Discrete Channel

1. From the PC’s Start Menu, start Alarmware and connect to the attached

Catalyst.

Saved: 2015-08-03

Filename:

Catalyst EtherNet Option Setup R5 V01.docx RACO Manufacturing and Engineering

3. In Alarmware, Click on Configuration > Channels

Saved: 2015-08-03

Filename:

Catalyst EtherNet Option Setup R5 V01.docx RACO Manufacturing and Engineering

Enter the desired Channel number and SNA. For this example we will use the

Health bit SNA 1*2*01992 and Channel 56. The rest of the setting can be left in

their default states for most applications. Any SNA can be assigned to any channel.

5. Click Change Mode. A window will appear very briefly as the Alarmware

downloads the configuration data to the Catalyst.

The mode is the type of data that the SNA contains. Discrete Mode means that

the SNA represents a single bit (like a PLC coil). The other mode is Analog

Mode, where the address represents a 16-bit integer. The mode is selected

automatically based on the SNA.

You can also change the other settings for this channel. This process is the

Saved: 2015-08-03

Filename:

Catalyst EtherNet Option Setup R5 V01.docx RACO Manufacturing and Engineering

same as when setting a physical address. Refer to the Catalyst manual for that

process.

6. At this point the Catalyst is fully configured to send an alarm on channel 56 if

communication between the PLC and Catalyst is lost.

Let’s also set a general alarm, for this example on Channel 5, SNA 1*2*00003.

Simply change the Channel Number and the SNA to the new values and Click

Change Mode. The Catalyst will save and update the settings immediately.

NOTE: Since the Discrete SNA 1*2*00003 uses one of the bits in the 16bit

Analog register at SNA 1*2*40001, that register cannot be used to store analog

data. Refer to Section C: SNA Discrete and Analog Register Addressing for

more information.

7. Repeat these steps to add additional alarms. When you have finished adding

alarms, Click Close to exit the Channel Settings window.

Assign and Configure an Analog Channel

1. From the PC’s Start Menu, start Alarmware v2.0 and connect to the attached

Catalyst.

2. In Alarmware, Click on Configuration > Channels, Enter the desired Channel

number and a SNA in the 4xxxx range (Ch. 2 and 1*2*40005 in this example)
