Chapter 3 Operation This chapter describes ENI/ENIW operation. The following information is included: • • • • • Operation Overview Operation Overview Allocation of Ethernet Connections ENI and ENIW Functional Overview General Ethernet Information RSLinx/RSWho Connectivity Example Using ENI/ENIW Interface Ethernet is the protocol used to transport TCP/IP messages. On top of TCP, EtherNet/IP is the open protocol used by the ENI and ENIW.
PAGE 32
3-2 Operation ENI and ENIW Functional Overview The ENI and ENIW provide EtherNet/IP connectivity for RS-232 devices that use DF1 full-duplex protocol. DF1 full-duplex is an open, point-to-point protocol used in any Allen-Bradley controller with an RS-232 port, and in many other devices. DF1 full-duplex supports up to 255 node addresses. The ENI and ENIW use these node addresses for different functions. The ENI and ENIW use a memory (node) map to provide access to the different functions you can perform.
PAGE 33
Operation 3-3 Table 3.1 Example Network IP Addresses IP Address ENI or ENIW Series Device 131.200.50.96 computer’s Ethernet card 131.200.50.97 Series B/C/D 1761-NET-ENI/1761-NET-ENIW #3 (1769-L20 or 1769-L3x CompactLogix controller) 131.200.50.98 Series A or B/C/D 1761-NET-ENI/1761-NET-ENIW #4 (MicroLogix 1500) The subnet mask for each Ethernet device is then, 255.255.0.0.
PAGE 34
3-4 Operation The ENI/ENIW allows you to connect from your PC to controllers over Ethernet. The following procedure can be used when the computer has a connection directly onto Ethernet (PCI card, PCMCIA interface, built in TCP/IP port, etc.) and also when the ENI/ENIW is plugged into the computer’s RS-232 (COMM) port. PC Connected Directly to Ethernet (RSLinx on Ethernet) IMPORTANT You must use RSLinx version 2.31.
PAGE 35
Operation 3-5 2. Select “Ethernet devices” from the available drivers, and then click “OK” to load the driver into RSLinx. TIP The RSLinx Ethernet/IP driver may also be used with series B (FRN 2.31) ENIs and higher. The advantage of this driver is that it can ‘discover’ the ENIs on a network even when the IP addresses have not been manually entered. The disadvantage of this driver is that the RSWho browse displays only the ENI and not the MicroLogix controller that is attached to the ENI’s serial port.
PAGE 36
3-6 Operation At that point, the station mapping screen will appear as illustrated here. Double click on the row below “Host Name”, and enter the TCP/IP addresses that match the devices on your network. When you are done entering the stations, click OK to close the station mapping window.
PAGE 37
Operation 3-7 4. Open the AB_ETH-1 tree on your computer. Autobrowse should be running and any active device that you have configured should be shown on the screen as illustrated below. TIP IMPORTANT If the ENI or ENIW shows up as an “Unrecognized Device”, you may need to install the latest ENI or ENIW (series B or series C/D) EDS file. You can download this file from http://www.ab.com/networks/eds/.
PAGE 38
3-8 Operation PC Connected to Ethernet via the ENI or ENIW As shown below, the ENI/ENIW can also be used to connect a computer’s RS-232 port to EtherNet/IP and allow program upload and download and online sessions with a maximum of four EtherNet/IP devices. (Note: The ENI/ENIW limits the number of concurrent outgoing connections to four).
PAGE 39
Operation 3-9 RSLinx Configuration 1. Open RSLinx. 2. Open the configure drivers dialog box. 3. Select RS-232 DF1 devices. Click Add New. 4. Configure AB_DF1-1 driver to match the example below. 5. Click OK when the AB_DF1-1 driver is configured. TIP The 1770-KF3/1747-KE device type only allows you to address nodes 0 to 31 (decimal). In order to address nodes 32 to 49, you must select the 1770-KF2/1785-KE device type and convert the octal addresses to decimal (408 = 3210 . . . 618 = 4910).
PAGE 40
3-10 Operation 6. If you have set up the ENI/ENIW Message Routing table with IP addresses in entries between 1 and 31, those devices should respond when you browse the AB_DF1 driver. TIP IMPORTANT IMPORTANT Publication 1761-UM006E-EN-P - August 2005 If you use the AB_DF1 driver through an ENI/ENIW, you may go online with CompactLogix controllers using RSLogix 5000 whether they are connected to Ethernet through series A or series B/C/D ENI/ENIW modules.

PAGE 54
4-14 ENI/ENIW Configuration (Nodes 241 to 254) Node 253 - Baud Rate The first time the ENI/ENIW is powered-up (out-of-the-box), it is set to Autobaud so that it can synchronize to the attached controller. The baud rate can be changed by sending a message to address 253 with one of the configuration values shown in the table below. Changes to the baud rate take effect when the ENI/ENIW power is cycled or when a Save configuration to flash command (write to node 248) is received.
PAGE 55
ENI/ENIW Configuration (Nodes 241 to 254) 4-15 Node 252 - BOOTP Configuration The ENI/ENIW allows the BOOTP request to be disabled by clearing the BOOTP Enable parameter in the channel Configuration File. BOOTP Enable behaves as follows: Table 4.
PAGE 56
4-16 ENI/ENIW Configuration (Nodes 241 to 254) instruction to the ENI/ENIW (or by using the ENI/ENIW Configuration Utility). 1. Configure a 485CIF/PLC2 write message in the Allen-Bradley controller. IMPORTANT To configure TCP/IP parameters in this manner, BOOTP and DHCP must be disabled. Only PLC2 type or 485CIF write messages can be used to configure the ENI/ENIW, node 250. 2. Set the destination (target) node to 250. Using node address 250 directs this message to the TCP/IP configuration function. 3.
PAGE 57
ENI/ENIW Configuration (Nodes 241 to 254) 4-17 Subnet Mask A subnet mask is used to interpret IP addresses when the network is divided into subnets. If your network is not divided into subnets, then leave the subnet mask at the default or allow the ENI/ENIW Configuration Utility to assign a default. The subnet mask defaults to auto-detect mode ‘out-of-box’. As long as the subnet mask is not manually set, the auto-detect mode follows the rules as shown below: Table 4.
PAGE 58
4-18 ENI/ENIW Configuration (Nodes 241 to 254) The security masks default value is 0.0.0.0 out-of-box, which is defined as “accept all register session requests”. A Security Mask of 255.255.255.255 is also defined as “accept all register session requests”. TIP The security mask acts as a filter on the source IP address such that any mask octet set to the value of 255 becomes “don’t care” octets in the source IP address and all other fields must match exactly.
PAGE 59
ENI/ENIW Configuration (Nodes 241 to 254) 4-19 Node 249 - From String Node 249 holds the ASCII string that is sent with any email message initiated by the ENI/ENIW. Criteria for a valid email From String include: • The From String remains at the default value unless changed by the user. See page 4-12 for default information. • The From String must contain an “@” symbol. • The From String cannot contain any spaces or special ASCII characters. • The maximum length of the From String is 64 characters.
PAGE 60
4-20 ENI/ENIW Configuration (Nodes 241 to 254) Node 245 - Configuration Security Mask The Configuration Security Mask can limit which computers are allowed to configure the ENI or ENIW over Ethernet, based on their IP Address. A Configuration Security Mask of 000.000.000.000 or 255.255.255.255 allows any computer to configure the ENI or ENIW over Ethernet.
PAGE 61
ENI/ENIW Configuration (Nodes 241 to 254) 4-21 The ENI/ENIW performs the following Email Authentication configuration operations when receiving a 485CIF/PLC2 Unprotected Write message of one element (integer) to Node 244. • 0 = Disabled • 1 = Enabled Node 243 - SMTP Email Authentication Password (Series D Only) Many open mail servers now require user authentication for email. Node 243 allows a 45 character Password to be defined for email service (series D units only).
PAGE 62
4-22 ENI/ENIW Configuration (Nodes 241 to 254) Node 241 - Ethernet Speed and Duplex Setting (Series D Only) This node allows speed and duplex settings of 10 Mbps or 100 Mbps and half-duplex or full-duplex to be forced. Auto negotiation may also be selected with this node. The ENI/ENIW performs the following Ethernet speed/duplex configuration operations when receiving a 485CIF/PLC2 Unprotected Write message of one element (integer) to Node 241.

Chapter 5 Peer-to-Peer Messaging This chapter describes messaging between the ENI/ENIW and DF1 devices.
PAGE 68
5-2 Peer-to-Peer Messaging IMPORTANT When the ENI/ENIW receives a 485CIF/PLC2 write message to a configuration node address (100 through 149), it closes any open communications currently active on that connection and reconfigures the IP address to match the new configuration. If the received data matches the current configuration, the ENI/ENIW closes any open communications with the destination device.

Peer-to-Peer Messaging IMPORTANT 5-3 In the ENI/ENIW, node addresses 45 through 49 are dedicated for sending messages to any Logix controllers with integral Ethernet ports. In addition, when sending messages to a ControlLogix controller via a 1756-ENBT, the controller MUST be in slot 0 of the ControlLogix chassis for the message to be delivered to it.

Chapter 6 EMail Messages (Node 50 to 99) This chapter describes using the ENI/ENIW’s email feature. The following topics are included: • Overview • Configuring Email • Sending an Email Message Overview The ENI/ENIW is capable of transmitting email messages generated by the attached controller. This provides an extremely versatile mechanism to report alarms, status, and other data-related functions.
PAGE 72
6-2 EMail Messages (Node 50 to 99) Configuring Email SMTP Email Address To configure the email function, at least two parameters must be configured: • SMTP Mail Server IP address - configured by sending a write message to node 251 (email server). See page 4-15 for more information. IMPORTANT The ENI/ENIW only accepts the configuration in the form of 4 elements (words) from an Integer file. • A “From” String - configure by sending a write message to node 249 (from string).
PAGE 73
EMail Messages (Node 50 to 99) 6-3 Destination Addresses The ENI/ENIW stores email addresses; it does not store the email messages. To store a destination address, write a message to a specific node number (nodes 150 to 199). The message data must be a string element that contains a valid email ASCII text string address, as illustrated in ST15:2 through ST15:5 in the example below. IMPORTANT Remember the following when setting up destination addresses: • The ENI/ENIW can store up to 50 email addresses.
PAGE 74
6-4 EMail Messages (Node 50 to 99) Message Fields (to, from, subject) The ENI/ENIW includes the “to”, “from”, and “subject” fields in the body of the message. The default “from” text is ENI0.0.0.0@eni1761.org (ENI192.168.1.254@ENI1761.org for series D). This can be changed in the ENI/ENIW configuration, Node 249. See page 6-2 or Chapter 4. The standard format of the “subject” line is: Subject: 1761ENI.
PAGE 75
EMail Messages (Node 50 to 99) IMPORTANT TIP 6-5 The ENI/ENIW does not support non-printable ASCII characters and may exhibit unpredictable behavior when these characters are used in an email message. Avoid using non-printable ASCII characters such as Carriage Return, Line Feed, Tabs, etc. The procedure to send configuration strings (nodes 150 to 199), or message strings (nodes 50 to 99) is exactly the same as discussed, “Configuring ENI/ENIW String Parameters” on page 4-24. 1.

8-2 Connecting CompactLogix Controllers on Ethernet System Diagram Figure 8.
PAGE 95
Connecting CompactLogix Controllers on Ethernet Purpose Provide Ethernet connectivity for CompactLogix controllers via the RS-232 serial port and the ENI/ENIW module. Scope Connecting CompactLogix controllers on Ethernet requires one ENI/ENIW per CompactLogix controller. The ENI/ENIW converts RS-232 hardware connections and DF1 full-duplex protocol to Ethernet hardware connections and EtherNet/IP protocol. 8-3 The ENI/ENIW must be configured with IP addresses assigned to node numbers 0 to 49.
PAGE 96
8-4 Connecting CompactLogix Controllers on Ethernet For this example, we will assign the following IP addresses to the devices on Ethernet: Table 8.1 Example IP Addresses for Ethernet Devices Device Node Address (for L20 MSG) IP Address SLC-5/05 1 131.200.50.92 1756-ENBT 45 131.200.50.93 1761-NET-ENI #2 N/A 131.200.50.94 1761-NET-ENI #1 N/A 131.200.50.95 Computer Ethernet Card N/A 131.200.50.96 IMPORTANT General CompactLogix Messaging Guidelines The IP addresses in Table 8.

We will use the PLC-5 Typed Write commands for this example.
PAGE 101
Connecting CompactLogix Controllers on Ethernet 8-9 The “ENI IP Addr” tab and the “Message Routing” tab in the ENI/ENIW Configuration Utility must be modified for the purposes of this example. We need to add the addresses of the SLC 5/05 and the 1756-ENBT to the ENI #2 Message Routing table. These addresses are taken from Table 3.1 on page 3-2. Set up the two ENI #2 tabs as follows: Figure 8.8 ENI #2 Configuration - ENI IP Addr Screen Figure 8.

PAGE 104
8-12 Connecting CompactLogix Controllers on Ethernet The Message Instructions for the CompactLogix controller, Rungs 2 through 8, used to configure the ENI/ENIW module, must be “PLC2 Unprotected Write” Message Type. The “Destination Element” can be any valid PLC2 command value. “010” is used in this example because it is the first available value that the software will allow. This parameter is not used by the ENI/ENIW, but must be a valid value for RSLogix 5000 to accept it.
PAGE 105
Connecting CompactLogix Controllers on Ethernet 8-13 Figure 8.13 ENI #2 Configuration - Message Communication Tab The MSG length is 8 bytes or 4 integer words. These 4 words contain the IP address for ENI #2 and are stored in tag ENI_IP_VALUE, which is a tag address containing 4 integer words. This is shown in the CompactLogix controller’s tag database shown below.

Appendix B BOOTP Configuration Method (default) BOOTP (Bootstrap protocol) is a low-level protocol that provides configuration information to other nodes on a TCP/IP network with DOS, Microsoft Windows, Windows NT, Windows 9x, VMS, and HP-UNIX platforms. BOOTP configuration files let you automatically assign IP addresses to the ENI/ENIW. You can also set Subnet Masks and Gateway addresses using BOOTP. DHCP (Dynamic Host Configuration Protocol) is a newer protocol used for the same purpose as BOOTP.
PAGE 130
B-2 BOOTP Configuration Method (default) Table B.1 TCP/IP Parameters Function Format Notes IP Address Integer This is a unique IP Address for the ENI/ENIW. Format is aaa.bbb.ccc.ddd. Default is 000.000.000.000. Subnet Mask optional(1) If not sent, the default mask is derived from the class of the IP address. See page 4-17 for more information on the subnet mask. Gateway optional(1) Only needed if a Gateway is present on the Subnet. Default is 000.000.000.

Appendix C 1761-NET-ENI/ENIW Performance Considerations Ethernet/IP Connections The ENI/ENIW supports 6 concurrent TCP/IP connections: 2 incoming, 2 outgoing and 2 that can be allocated as incoming or outgoing. Connection use can be viewed on the Diagnostics tab of the ENI/ENIW web page (series D only). Each TCP/IP connection simultaneously supports up to: • 4 CIP connections • 5 Unconnected sends Packet Size Limitations Each TCP/IP connection has its own DF1 queue.

C-2 1761-NET-ENI/ENIW Performance Considerations Data Throughput In tests performed using the RSLinx OPC Test Client, the ENI/ENIW (series D) was connected to a MicroLogix 1500 with channel 0 set to 38.4 kbaud. The Ethernet port was connected to the computer through a 10/100 Mbps switch.
PAGE 135
Glossary Autobaud A feature that allows a communications port to automatically synchronize to the device or network that it is attached to. This feature typically minimizes the amount of configuration required, and also makes is easier to replace devices. Auto BCC/CRC Sends a test message during autobaud to detect which Error Detecting setting to use, BCC or CRC. This will not occur for fixed baud rate settings. The ENI/ENIW uses CRC for fixed baud rates.
PAGE 136
Glossary 2 IP (Internet Protocol) IP specifies the format of packets and the addressing scheme. Most networks combine IP with a higher-level protocol called Transport Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP by itself is something like the postal system. It allows you to address a package and drop it in the system, but there's no direct link between you and the recipient.
PAGE 137
Glossary 3 Security Mask The Security Mask, when configured, allows you to restrict incoming TCP/IP and/or UDP messages to have source IP addresses that are within some prescribed range. For example, if you wanted to restrict all message sources to be from within a company’s allocated IP address range, a Security Mask could be configured that would block any IP address outside that range.
