Chapter 5 Control I/O This chapter describes how a controller controls distributed I/O over an EtherNet/IP network. An EtherNet/IP communication module connects the controller to the network. Set Up the Hardware Topic Page Set Up the Hardware 47 Select a Remote Adapter 57 Set the Requested Packet Interval (RPI) 58 Access Distributed I/O 59 In this example, the Logix5000 controller uses an EtherNet/IP communication module to connect to the EtherNet/IP network.
Chapter 5 Control I/O A Logix5000 controller establishes direct or rack-optimized connections to communicate with I/O modules. Digital I/O modules support either connection type, but analog I/O modules support only direct connections. You must complete these tasks before your controller can communicate with distributed I/O modules over an EtherNet/IP network: • Set the IP addresses for each EtherNet/IP communication module. • Connect all wiring and cabling.
Control I/O Chapter 5 To build the I/O configuration for a typical distributed I/O network, follow these steps. 1. Add the local communication module, that is, the bridge. 2. Add the remote adapter for the distributed I/O chassis or DIN rail. 3. Add the I/O module. This graphic shows the consumer controller’s I/O configuration after distributed I/O modules are added. IMPORTANT I/O is controlled on the same subnet and cannot be processed via a router.
Chapter 5 Control I/O Add an I/O Module To add a module to the I/O Configuration folder, follow these steps. 1. In the Controller Organizer, right-click the remote communication module and choose New Module. The Select Module dialog box appears. 2. Choose the module you wish to add and click OK. Depending on the I/O module, the Select Major Revision dialog box may appear. If the dialog box appears, choose the module’s major revision and click OK.
Control I/O Chapter 5 The Module Properties dialog box appears. 3. In the Name field, type the name of your I/O module. 4. In the Slot field, type the slot number in which your I/O module will reside. 5. From the Comm Format pull-down menu, choose a communication format. For more information on the selection of communication formats, see Set the Requested Packet Interval (RPI) on page 58. 6. Click OK to see the rest of the Module Properties dialog box. 7. Configure the module as necessary.
Chapter 5 Control I/O Select a Communication Format When configuring an I/O module, you must select a communication format. The type of communication format determines the data structure for the module’s tags. Many I/O modules support different formats. Each format uses a different data structure.
Control I/O Chapter 5 Term Definition Rack-optimized connection For digital I/O modules, you can choose rack-optimized communication. A rack-optimized connection consolidates connection usage between the controller and all the digital I/O modules in the chassis (or DIN rail). Rather than having individual, direct connections for each I/O module, there is one connection for the entire chassis (or DIN rail).
Chapter 5 Control I/O Direct Connections For I/O Modules In this example, assume that each distributed I/O module is configured for a direct connection to the controller.
Control I/O Chapter 5 Rack-optimized Connections for I/O Modules In this example, assume that each digital I/O module is configured for a rackoptimized connection to the controller. Analog modules must be configured for direct connections.
Chapter 5 Control I/O Ownership In a Logix5000 system, modules multicast data. Therefore, multiple modules can receive the same data at the same time from a single module. When choosing a communication format, decide whether to establish an owner-controller or listen-only relationship with the module. Ownership Type Description Owner controller The controller that creates the primary configuration and communication connection to a module.
Control I/O Chapter 5 Table 6 - Input and Output Modules - Differences in Ownership Control This Ownership Description Input modules Owner An input module is configured by a controller that establishes a connection as an owner. This configuring controller is the first controller to establish an owner connection. Once an input module has been configured and owned by a controller, other controllers can establish owner connections to that module.
Chapter 5 Control I/O Set the Requested Packet Interval (RPI) When you configure an I/O module, you define the requested packet interval (RPI) for the module. Only data-producing modules require an RPI. For example, a local EtherNet/IP communication module requires no RPI because it produces no data for the system. Instead it functions only as a bridge. To set an RPI, follow these steps. 1.
Control I/O Chapter 5 4. From the Requested Packet Interval (RPI) menu, enter the rate at which you want data to be updated over a connection. Only set the RPI to the rate the application requires. IMPORTANT The RPI determines the number of packets per second that the module produces on a connection. Each module can produce only a limited number of packets per second. Exceeding this limit prevents the module from opening more connections. 5. Click OK.

Chapter 6 Interlocking and Data Transfer between Controllers This chapter describes how to share data by interlocking controllers (producing and consuming tags) and transferring messages between controllers via an EtherNet/IP network.
Chapter 6 Interlocking and Data Transfer between Controllers Set Up the Hardware In this example, the controller in the local chassis produces a tag that the Logix5000 controller in the remote chassis consumes. The local controller can also send a MSG instruction to the remote controller.
Interlocking and Data Transfer between Controllers Chapter 6 You must complete these tasks before Logix5000 controllers can share tags over an EtherNet/IP network: • Set the IP addresses and other network parameters for each EtherNet/IP communication module. • Connect all wiring and cabling. • Configure a communication driver (such as AB-ETHIP-1) for the programming workstation.
Chapter 6 Interlocking and Data Transfer between Controllers Terminology A Logix5000 controller can produce (broadcast) and consume (receive) systemshared tags. Table 11 - Tag Definitions Term Definition Produced tag A tag that a controller makes available for use by other controllers. Multiple controllers can simultaneously consume (receive) the data. A produced tag sends its data to one or more consumed tags (consumers) without using logic.
Interlocking and Data Transfer between Controllers Chapter 6 All EtherNet/IP communication modules support as many as 32 produced multicast connections. Because each tag that passes through an EtherNet/IP communication module uses a single connection, the number of available connections limits the total number of tags that can be produced or consumed. If the communication module uses all of its connections for I/O and other communication modules, no connections remain for produced and consumed tags.
Chapter 6 Interlocking and Data Transfer between Controllers Produce a Tag To produce a tag, configure the produced tag in the Studio 5000 Logix Designer project for the local (producer) controller. You do not have to configure the consumer controllers in the I/O Configuration folder of the producer controller. Configure the Produced Tag To configure the produced tag, follow these steps. 1. In the producer’s Controller Organizer, right-click the Controller Tags folder and choose Edit Tags.
Interlocking and Data Transfer between Controllers Chapter 6 The Tag Properties dialog box appears. 3. From the Type pull-down menu, choose Produced. 4. Click Connection. The Produced Tag Connection dialog box appears. 5. In the Max Consumers field, type the maximum number of controllers that will consume (receive) the tag. 6. Click OK.
Chapter 6 Interlocking and Data Transfer between Controllers To consume a produced tag, specify both the producer controller and the produced tag in the Studio 5000 Logix Designer project for the remote (consumer) Logix5000 controller. Consume Data Produced by Another Controller Add the Producer Controller to the Consumer’s I/O Configuration Add the producer controller to the remote controller’s I/O Configuration folder.
Interlocking and Data Transfer between Controllers Chapter 6 To add a producer controller to the I/O Configuration folder, follow these steps. 1. In the Controller Organizer, right-click the remote backplane and choose New Module. The Select Module Type dialog box appears. 2. Click the By Category tab and choose your producer controller. 3. Click OK. Depending on the controller type, the Select Major Revision dialog box may appear.

The Tag Properties dialog box appears. 3. From the Type pull-down menu, choose Consumed. 4. In the Data Type field, type a data type that matches the type assigned to the produced tag. 5. Click Connection. The Consumed Tag Connection dialog box appears. 6.
Chapter 6 Interlocking and Data Transfer between Controllers 7. In the Remote Data field, type the tag name or instance number of the produced data. 8. In the RPI field, type the requested packet interval (RPI) for the connection. Only set the RPI to the rate the application requires. IMPORTANT The RPI determines the number of packets per second that the module will produce on a connection. Each module can only produce a limited number of packets per second.
Interlocking and Data Transfer between Controllers Guidelines for Message (MSG) Instructions Chapter 6 Follow these guidelines. Table 14 - MSG Instruction Guidelines Guideline Description For each MSG instruction, create a control tag. Each MSG instruction requires its own control tag: • Data type = MESSAGE • Scope = controller • The tag cannot be part of an array or a user-defined data type. Keep the source and destination data at the controller scope.
Chapter 6 Interlocking and Data Transfer between Controllers Connections for Messages Messages transfer data to other modules, such as other controllers or operator interfaces. Each message uses one connection, regardless of how many modules are in the message path. To conserve connections, you can configure one message to read from or write to multiple modules. These connected messages can leave the connection open (cache) or close the connection when the message is done transmitting.
Interlocking and Data Transfer between Controllers Enter Message Logic Chapter 6 To send or receive data from an EtherNet/IP communication module via a message, you must program a MSG instruction in the local controller’s logic. If the target module is configured in the I/O Configuration folder of the controller, browse to select the module or manually type the message path in the MSG instruction.
Chapter 6 Interlocking and Data Transfer between Controllers Select a communication format for a communication module based on the modules in its remote chassis.
Interlocking and Data Transfer between Controllers Chapter 6 2. Click the By Category tab and choose your EtherNet/IP communication module. 3. Click OK. Depending on the EtherNet/IP communication module, the Select Major Revision dialog box may appear. If the dialog box appears, choose the module’s major revision and click OK.

Interlocking and Data Transfer between Controllers Chapter 6 For a message to a ControlLogix controller, this Studio 5000 environment Message Configuration dialog box appears. For a message to a SLC 500 or PLC-5 processor, this RSLogix Message Configuration dialog box appears.
Chapter 6 Interlocking and Data Transfer between Controllers 5. If the target module is configured in the I/O Configuration folder of the originating controller, click Browse to select the module or manually type the path to the target module. A manually typed path begins with the name of the local EtherNet/IP communication module, the port the message exits (2 for EtherNet/IP), and the IP address of the next module in the path, which could be the target module.
Interlocking and Data Transfer between Controllers Communicate with PLC-5 or SLC Controllers Chapter 6 If the message is to a PLC-5 or SLC 500 processor and it reads or writes integers (not REALs), use a buffer of INTs in the message. Remember these considerations: • Logix5000 controllers execute more efficiently and use less memory when working with 32-bit integers (DINTs). • PLC-5 and SLC 500 processors require 16-bit integers. • Messages require an INT buffer.
Chapter 6 Interlocking and Data Transfer between Controllers Mapping Tags A Logix5000 controller stores tag names on the controller so that other devices can read or write data without having to know physical memory locations. Many products only understand PLC/SLC data tables, so the Logix5000 controller offers a PLC/SLC mapping function that enables you to map Logix tag names to memory locations.
Interlocking and Data Transfer between Controllers EXAMPLE Chapter 6 Read integers from a PLC-5 controller. ATTENTION: When condition turns on, reads 16-bit integer values (INTs) and stores them in int_buffer. Then the FAL instruction moves the values to dint_array. This converts the values to 32-bit integers (DINTs), for use by other instructions in the ControlLogix controller. EXAMPLE Write integers to a PLC-5 controller.
Chapter 6 Interlocking and Data Transfer between Controllers Receive MSGs from PLC-5 or SLC 500 Controllers To receive MSGs from PLC-5 or SLC 500 processors, follow these steps. 1. If the originating controller is a PLC-5 or SLC 500 processor, in the MSG instruction, select PLC5.
Chapter 7 Send Email Introduction This chapter describes how to send an email through an EtherNet/IP communication module. IMPORTANT The 1756-EN2TSC module does not support this capability.
Chapter 7 Send Email The EtherNet/IP communication module sends only the content of a MSG instruction as an email to a mail relay server. Delivery of the email depends on the mail relay server. The EtherNet/IP communication module does not receive email.
Send Email Send Email via a Controllerinitiated Message Instruction Chapter 7 A Logix controller can send a generic CIP message instruction to the EtherNet/ IP communication module that instructs the module to send an email message to a SMTP mail relay server using the standard SMTP protocol. This automatically communicates controller data and application conditions to appropriate personnel.
Chapter 7 Send Email The String Browser dialog box appears. 2. Type the IP address or host name of the mail server. 3. Click OK. The tags for the email text and transmission status can contain up to 474 characters. For these tags, you must create a user-defined STRING data type. The default STRING data type in the Studio 5000 environment is not large enough for most email text. To create a user-defined STRING data type, follow these steps. 1.
Send Email Chapter 7 2. Create the EmailString data type. 3. Create one controller-scoped tag, such as EWEB_EMAIL, of this new data type to contain the email text. 4. Create a second controller-scoped tag, such as EmailDstStr, of this new data type to contain the transmission status. Both of these tags are of type EmailString. 5. Click ... in the Value column of the Controller Tags dialog box. Tag for Status Tag for Email Text The String Browser dialog box appears. 6. Type your email.
Chapter 7 Send Email For more information on using ladder logic to manipulate string data, see the Logix5000 Controllers Common Procedures Programming Manual, publication 1756-PM001. Enter the Ladder Logic Ladder logic requires two MSG instructions. One MSG instruction configures the mail server and needs to be executed only once. The second MSG instruction triggers the email. Execute this email MSG instruction as often as needed. SetServer The first rung configures the mail server.
Send Email Chapter 7 2. In the Path field, type the path for the MSG instruction. The path starts with the controller initiating the MSG instruction. Type the number of the port from which the message exits and the address of the next module in the path. For example, if the EtherNet/IP communication module is in the same chassis as the controller and is in slot 2, the path is: 1, 2.
Chapter 7 Send Email Configure the MSG Instruction That Contains the Email Text To configure the MSG instruction that contains the email text, perform this procedure. 1. Click the Configuration tab. The Source Length is the number of characters in the email tag plus 4 characters. In this example, the email text contains 65 characters. 2. Configure the MSG parameters for sending an email. • From the Service Type pull-down menu, choose Custom. • In the Service Code field, type 4b.
Send Email Chapter 7 3. Click the Communication tab. 4. In the Path field, type the path from the controller to the EtherNet/IP communication module. The path starts with the controller initiating the MSG instruction. The second number in the path represents the port from which the message exits and the address of the next module in the path. For example, if the EtherNet/IP communication module is in the same chassis as the controller and is in slot 2, the path is: 1, 2. 5.
Chapter 7 Send Email Enter Email Text Use the string browser to type the text of the email. To include To:, From:, and Subject: fields in the email, use symbols to separate each of these fields. The To: and From fields are required; the Subject: field is optional. For example: To: email address of recipient From: email address of sender Subject: subject of message body of email message An email message must not exceed 474 characters in length.
Send Email Chapter 7 Table 20 - Email Status Code Descriptions Error Code (Hex) Extendederror Code (Hex) Description 0xFF 0x0104 Unable to connect to SMTP mail server set in Attribute 5. If the mail server address is a host name, make sure that the device supports DNS, and that a Name Server is configured. If the host name is not fully qualified, for example, ‘mailhost’ and not ‘mailhost.xx.yy.com’ then the domain must be configured as ‘xx.yy.com’.
