ControlLogix EtherNet/IP Module Important User Information Solid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some important differences between solid-state equipment and hard-wired electromechanical devices.
ControlLogix EtherNet/IP Module 3 North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations. Informations sur l’utilisation de cet équipement en environnements dangereux. Products marked “CL I, DIV 2, GP A, B, C, D” are suitable for use in Class I Division 2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only.
ControlLogix EtherNet/IP Module Environment and Enclosure ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
ControlLogix EtherNet/IP Module 5 Prevent Electrostatic Discharge ATTENTION: This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • • • • • • Touch a grounded object to discharge potential static. Wear an approved grounding wriststrap. Do not touch connectors or pins on component boards. Do not touch circuit components inside the equipment. Use a static-safe workstation, if available.
ControlLogix EtherNet/IP Module About the Module Use this figure to identify the external features of the module.
ControlLogix EtherNet/IP Module 7 Before You Begin Before you install the module, you must install and connect a ControlLogix chassis and power supply. 2 1 20805-M Item Description Item Description 1 1756-A4 chassis 2 Power supply To install these products, refer to these publications.
ControlLogix EtherNet/IP Module Determine Module Slot Location Install the module in any slot in the ControlLogix chassis. You can install multiple 1756-EN2T modules in the same chassis. The following figure shows chassis slot numbering in a four-slot chassis. Slot 0 is the first slot and is always the leftmost slot in the rack.
ControlLogix EtherNet/IP Module 9 Set the Network Address The module ships with the rotary switches set to 999 and BOOTP enabled. You can set the network Internet Protocol (IP) address three ways. • Use the rotary switches on the top of the module. • Use a BOOTP server or Dynamic Host Configuration Protocol (DHCP) server, such as Rockwell Automation BOOTP/DHCP. • Use the Rockwell Automation RSLinx or RSLogix 5000 software.
ControlLogix EtherNet/IP Module To reset the module to its initial out-of-the-box settings, reset the switches to 888 and cycle power. IMPORTANT Do not use the 888 switch setting during normal module operation. After cycling power with the switches set to 888, remove the module and set the switches to their final value. When you set the rotary switches to a value other than 888, or to the valid IP address values 001…254, the software configuration determines the IP address.
ControlLogix EtherNet/IP Module 11 Install the Module Follow this procedure to install the module. 1. Align the circuit board with top and bottom guides in the chassis. 1 Item Description 1 Circuit board 2. Slide the module into the chassis.
ControlLogix EtherNet/IP Module Make sure that the module backplane connector properly connects to the chassis backplane. TIP The module is properly installed when it is flush with the power supply or other installed modules. Connect the Module to the EtherNet/IP Network WARNING: If you connect or disconnect the communication cable with power applied to this module or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. 1.
ControlLogix EtherNet/IP Module 13 1 2 Item Description Item Description 1 USB port 2 RJ45 connector (underneath module) IMPORTANT We recommend connecting the module to the network via a 100 MB Ethernet switch, which will reduce collisions and lost packets and increase network bandwidth.
ControlLogix EtherNet/IP Module Program the Module via the USB Port WARNING: The USB port is intended for temporary local programming purposes only and is not intended for permanent connection. If you connect or disconnect the USB cable with power applied to this module or any device on the USB network, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. A Samtec Inc.
ControlLogix EtherNet/IP Module 15 Configure the Module Follow these steps to configure the module. 1. In RSLogix 5000 software, from the Controller Organizer, select New Module. 2. Select the module you want to configure. For more configuration information, refer to the EtherNet/IP Modules in Logix5000 Control Systems User Manual, publication ENET-UM001. View or download this publication at http://www.rockwellautomation.com/literature.
ControlLogix EtherNet/IP Module Check Power Supply and Module Status Check the status indicators and alphanumeric display to determine whether the power supply and module are operating properly.
ControlLogix EtherNet/IP Module 17 The alphanumeric display should cycle through these states: • TEST • PASS • OK • REV x.x where x.x is the module’s firmware revision. The display then alternates between OK and the module’s EtherNet/IP address. Install or Remove the Module Under Power You can install or remove this module while chassis power is applied. WARNING: When you insert or remove the module while backplane power is on, an electrical arc can occur.
ControlLogix EtherNet/IP Module 2. Slide the module out of the chassis. IMPORTANT If you want to replace an existing module with an identical one, and you want to resume identical system operation, you must install the new module in the same slot.
ControlLogix EtherNet/IP Module 19 Interpret the Status Indicators If the alphanumeric display and status indicators do not sequence through the expected states, refer to these tables. The three bi-color (red/green) status indicators on the module provide diagnostic information about the module and its connections to the network.
ControlLogix EtherNet/IP Module Status Indicators Indicator Status Description NET Off The module is not powered. Verify that there is chassis power and that the module is completely inserted into the chassis and backplane. The module does not have a valid IP address. Make sure the module has been configured with a valid IP address. Flashing green The module has an IP address, but has no established connections. Green The module has an IP address and at least one established connection.
ControlLogix EtherNet/IP Module 21 Status Indicators Indicator Status Description OK Off Verify that the module has 24V DC chassis power and that the module is completely inserted into chassis and backplane. Flashing green The module is not configured. Green The module is operating correctly. Flashing red The module detected a recoverable fault. A configuration error may have caused the fault. Check the module configuration. If necessary, reconfigure the module.
