Chapter 1 Introduction About Assembly Connections This document describes Assembly connections, a new connection type for POINT I/O and ArmorPOINT I/O EtherNet/IP adapters. These adapters currently support Rack Optimized connections between ControlLogix or CompactLogix controllers and the discrete I/O modules in the chassis. They are also capable of bridging direct connections between any EtherNet/IP-capable connection originator and the I/O modules, via the backplane.
2 Introduction Data Headers In the Target to Originator (T → O) direction, the adapter can be configured to produce a status header for the connection. The header consists of an 8-byte bitmap, where bits 1 - 63 indicate the health of each of the 63 possible backplane connections. This is similar to existing Rack Optimized connections. A "1" indicates that a module is not connected or that slot is not populated. A "0" indicates that the module is actively participating in the connection.

Chapter 2 Configuration About This Chapter This chapter describes the various configuration options that you can use to set up assembly connections. Configure the Connection This connection is accepted with or without a configuration assembly present. If a configuration assembly is present, it must contain the following minimum information.
6 Configuration Data Alignment Some computing devices require data to be aligned on boundaries that are proper for their data type. There are several alignment options available to reduce or prevent shifting operations in the originator: Byte Boundaries Each node's I/O data is mapped at the next available byte. Byte data can appear at any address. Word Boundaries If a node's I/O data is one byte in length, it is mapped at the next available byte.
Configuration 7 When Fixed Boundaries are selected, the formula for mapping is: H+(N-1)(size per slot), where N = slot position and H is the size of the optional status header (8 if used, 0 if not used). The choice of alignment is highly dependent on the originator used and application-specific requirements. • If data size is at a premium, Byte alignment is the most efficient choice.
8 Configuration Module Configuration Sent with the Connection Request Individual module configuration must be manually constructed and appended to the minimal configuration assembly specified in the table Minimal Adapter Configuration Assembly on page 5. For each module that needs to be configured, the following information must be provided: Module Configuration Information Field Data Type Description Slot number USINT The slot number to identify modules that require configuration data.
Configuration Calculate the Connection Size 9 The I/O assembly size is limited to the maximum size that can be specified in the standard Forward_Open service (509 bytes). The size needs to be manually calculated based on the alignment choices, inclusion of the optional status header, and the I/O sizes for the modules present in the chassis. The adapter validates the connection size in the forward open against what it calculates from the backplane and the alignment choice.

Configuration 11 1. Open the adapter's web page and select the Diagnostics folder. 2. On the Diagnostic Messaging tab, enter the Slot, Class, Instance, and Attribute to get the adapter's calculated connection sizes.
12 Configuration Diagnostic Messaging Field Description Field Description Instance 100 (O → T data) 101 (T → O data with status) 103 (T → O data without status) Attribute 4 Response 8E 00 00 00 xx xx 8E 00 — Indicates message was processed successfully 00 00 — 0 = success. Non-zero indicates an error code xx xx — Indicates size (Little Endian format)(1) (1) in Little Endian format, the least significant byte is shown first.
Chapter 3 Using an Assembly Connection Use an Assembly Connection with RSNetWorx for EtherNet/IP This section provides an illustration of the steps needed to configure the Assembly connection using RSNetWorx for EtherNet/IP. 1. Browse the EtherNet/IP network. 2. Select the connection originator that will make the connection to the 1734-AENT. Right click that device and select Scanlist Configuration to launch the Scanlist Configuration tool.
14 Using an Assembly Connection 3. Right click the targeted adapter and select Insert Connection to display the Connection Properties dialog. 4. On the Connection tab of this dialog, select the connection from the Connection Name pull-down (for example, Exclusive Owner and Listen-Only connections). Listen-Only connections are only accepted if an Exclusive Owner connection already exists.
Using an Assembly Connection 15 You can also select the Requested Packet Interval and connection sizes. For a full discussion on connections sizes, refer to the Configuration Setting tab step that follows and Calculate the Connection Size. The defaults reflect an empty system (with the adapter only). TIP In RSNetWorx, the 4-byte Run/Idle header is not considered when calculating the Output Size. When you enter the connection size on this dialog, make sure to subtract 4 bytes from your calculated size.
16 Using an Assembly Connection 6. The Configuration Setting tab displays the configuration options for the connection. Here, you can specify the Chassis Size and Data Alignment. The terms T2O and O2T are abbreviations for Target to Originator and Originator to Target. TIP Remember when specifying the Chassis Size to include 1 for the adapter. See Data Alignment for alignment choices.
Using an Assembly Connection 17 Add the Hardware to the I/O Configuration Tree 1. Add a new module to the Ethernet network in the I/O Configuration section of the Controller Organizer pane. 2. Select a Generic Ethernet Module.
18 Using an Assembly Connection Enter the Connection Parameters In the New Module Properties dialog, enter Connection Parameters, the Comm Format, the module's IP Address, and a name. Enter a Name for the module that RSLogix 5000 uses in the tags that are created for this module. The Data - SINT Comm Format should be selected, indicating that all sizes are to be interpreted as a number of bytes.
Using an Assembly Connection 19 Controller Tags by right-clicking the Controller Tags option from the Controller Organizer pane. Select Monitor Tags. Monitor Tags You should see three Tags with the module's name. They will have an C, I, or O suffix denoting Configuration, Input, or Output respectively. Note that the I and O Tags are sized according to the sizes that were entered on the properties page. The C Tag always has 400 bytes allocated for it regardless of the size specified.
20 Using an Assembly Connection and consumed alignment choice is Double Word alignment which is enumerated as a 4. See the following table for valid alignment values. Alignment choices for configuration header Alignment Choice Value Byte 0 Word 2 Double Word 4 Fixed size per slot 0xFF Add I/O Module Configuration If individual module configuration is required, it can be appended to the configuration header. In the example shown below a 1734-OB4E module is being configured.
Using an Assembly Connection 21 For more information on configuration, see 1734/1738 I/O Module Assembly Information. After the configuration has been entered into the tag, remember to save the RSLogix 5000 project. The tags are only retained upon a save. Also remember that any configuration added here must be reflected in the Configuration Size of the Connection Parameters entered on the Module Properties dialog.
22 Using an Assembly Connection The error shown above was created by entering an invalid configuration assembly size on the Module Properties page. A size of 18 bytes was entered. The error here points to an offset of 0x000b (11 decimal). If we return to the configuration tag, byte 0x000b is the location that contains the size of the I/O module configuration. The header is 10 bytes and the module has 8 bytes of configuration.
Chapter 4 Assembly Structure Assembly Structure Examples Byte, Word, and Double Word Alignment The following chassis is used to demonstrate how the data is aligned for the Byte, Word, and Double Word alignment options. This chassis was intentionally assembled as shown to demonstrate as many use cases as possible. Discrete and analog modules are intermixed. An ARM module is used to reserve space for a future device.
