Package Contents Your package contains: • 1 ArmorBlock LP2 Module • Installation Instructions Publication 1792D-5.26 - January 1999 2 4 Sinking Input / 4 Output Module European Union Directive Compliance If this product has the CE mark it is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives. EMC Directive This product is tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) and the following standards, in whole or in part, documented in a technical construction file: • EN 50081-2 EMC - Generic Emission Standard, Part 2 - Industrial Environment • EN 50082-2 EMC - Generic Immunity Standard, Part 2 - Industrial Environment This product is intended for use in an industrial environment. Low Voltage Directive This product is tested to meet Council Directive 73/23/EEC Low Voltage, by applying the safety requirements of EN 61131-2 Programmable Controllers, Part 2 - Equipment Requirements and Tests. For specific information required by EN 61131-2, see the appropriate sections in this publication, as well as the following Allen-Bradley publications: • Industrial Automation Wiring and Grounding Guidelines For Noise Immunity, publication 1770-4.1 • Automation Systems Catalog, publication B111 Install Your ArmorBlock LP2 I/O Module To install the module: • Set the node address and baud rate. • Mount the module. • Connect the unit to the DeviceNet trunk and the auxilary power source. • Connect the cord sets. Set the Node Address Set the node address using RSNetworx for DeviceNet software, DeviceNetManager software, or another software configuration tool. The module is equipped with AutoBaud detect. AutoBaud lets the module read the settings already in use on your DeviceNet network and automatically adjusts to follow those settings.

Attach the module using the dimensions shown below. 1.95 in 49.5mm 12in 305mm I0 I3 I1 I2 Network Status 4.21 in 107mm Module Status 0.25 in 6.25mm 1.02 in 26.0mm 2. Connect the grey DeviceNet cable to the DeviceNet trunk. Use the 1485P-P1R5-MN5R1 T-Part tap to connect to round media. Use the 1485P-P1E4-R5 to connect to the Kwik Link flat media system. Connect the Input / Output Cord Sets to the LP2 Module This module uses 5 pin micro (12mm) style PCB mounted connectors. Four micro caps cover the connectors on your module. Remove the caps and connect your cord sets to the appropriate ports. This product has two inputs or outputs per I/O connector. Use a “Y” splitter cable for access to all I/O connections. For more information on these cables, see the Product Data guide publication 1792-2.1. Use the micro caps to cover and seal unused ports. Pinout diagrams for the connectors are shown next. 2 1 5 3 4 2 1 5 4 3 Input Micro-Connector (View into Sockets) Pin 1 Sensor Source Voltage Pin 2 Input B Pin 3 Return Logic Ground1 Pin 4 Input A Pin 5 Not Used Output Micro-Connector (View into Sockets) Pin 1 Not Used Pin 2 Output B Pin 3 Auxilary Power Ground Pin 4 Output A Pin 5 Not Used 41452 1 Logic Ground is approximately 0.4V above DeviceNet V-measured at the module. Publication 1792D-5.26 - January 1999 4 4 Sinking Input / 4 Output Module ATTENTION: ! • Make sure to connect the proper color coded cables together. DeviceNet cable should connect to DeviceNet cables and auxillary outputs should match auxillary outputs. • Make sure all connectors and caps are securely tightened to properly seal the connections against leaks and maintain IP67 requirements • For maximum noise immunity, input and output cable return wires must be properly terminated. When inputs and outputs are connected in loopback, return wires should be connected together. • I/O cable length should be less than 30 meters. I/O connectors for this module are shown below.

Publication 1792D-5.26 - January 1999 4 Sinking Input / 4 Output Module 5 Communicate With Your ArmorBlock LP2 I/O Module This ArmorBlock module’s I/O is exchanged with the master through a polled, change of state, or cyclic connection. The module consumes and produces I/O data as follows: Type of I/O Connections Consumes Produces Cyclic 1 Byte 1 Byte Polled 1 Byte 1 Byte Change of State 1 Byte 1 Byte Cyclic - allows configuration of the block as an I/O client. The block will produce and consume its I/O cyclically at the rate configured. Polled - a master initiates communication by sending its polled I/O message to the module. The 4 input / 4 output module consumes the message, updates outputs, and produces a response. The response has input data, and the status of the Auxiliary power. Change of state - productions occur when an input changes. If no input change occurs within the expected packet rate, a heartbeat production occurs. This heartbeat production tells the scanner module that the I/O module is alive and ready to communicate. Consumption occurs when data changes and the master produces new output data to the I/O module. Refer to the table below for the word/bit definitions.
