Installation Instructions Cat. No. 1792-OB8PLP This 1792 ArmorBlock I/O block module (Cat. No. 1792-OB8PLP) contains I/O circuits, a built-in power supply, and a built-in DeviceNet I/O adapter. Because of its sealed housing, this 1792 I/O block requires no enclosure. It is compatible with PLC or SLC programmable controllers using DeviceNet scanners. The I/O values are accessible from the PLC or SLC programmable controller data table. This ArmorBlock-LP module has no switches to set. You set module parameters using the DeviceNet Manager Software (cat. no. 1787-MGR) or similar configuration tool.

EMC Directive This apparatus is tested to meet Council Directive 89/336/EEC Electromagnetic Compatibility (EMC) using a technical construction file and the following standards, in whole or in part: • EN 50081-2 EMC – Generic Emission Standard, Part 2 – Industrial Environment • EN 50082-2 EMC – Generic Immunity Standard, Part 2 – Industrial Environment The product described in this manual is intended for use in an industrial environment. Low Voltage Directive This apparatus is also designed 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 that the above norm requires, see the appropriate sections in this manual, as well as the following Allen-Bradley publications: • Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1 • Automation Systems Catalog, publication B111 Publication 1792-5.7 – December 1997 ArmorBlock-LP 8 Output Module 3 Install Your ArmorBlock-LP Module Installation of the ArmorBlock-LP module consists of: • setting the node address and communication rate in the ArmorBlock module • mounting the ArmorBlock module • connecting the wiring • communicating with your module Set the Node Address Each ArmorBlock-LP comes with its internal program set for node address 63 and a communication rate of 125K bps. To set the node address and communication rate, you need the following: • host computer with DeviceNet Manager Software (or similar configuration software tool) • 1770-KFD RS-232 module (or similar interface) • suitable cables to connect the 1770-KFD to your module and to connect the 1770-KFD to your host computer Set up a system (as shown below) to communicate with your ArmorBlock module to set the node address and communication rate to meet your system requirements.

When set for Polled, Bit Strobe, or change of state, the module consumes and produces as follows: Type of I/O Connections Consumes Produces Polled 1 Bytes 1 Byte Bit Strobe 0 Bytes 1 Byte Change of State 0 Bytes 1 Byte Polled device – a master initiates communication by sending its polled I/O message to the ArmorBlock module. The 8 output module consumes the message, updates outputs, and produces a response that reflects the status of its output faults. Change of state device – productions occur when a fault condition changes. If no fault condition occurs within the “expected packet rate,” a heartbeat production occurs. This heartbeat production tells the scanner module that the ArmorBlock module is alive and ready to communicate. Bit Strobe device – a master initiates communication by sending its bit strobe I/O message. All bit strobed devices then respond. The 8 output module consumes the message, and produces a response that reflects the status of output faults.
