ABB INNIS01 Network Processing Module
Hardware Architecture
The ABB INNIS01 network processing module adopts a compact design with a sturdy and durable housing, which can adapt to the complex and changing environment of industrial sites, such as high temperature, humidity, strong electromagnetic interference and other scenarios. It integrates high-performance processors and abundant storage resources internally, with powerful data processing capabilities that can quickly parse, forward, and process network data; Storage resources provide strong support for the stable operation of modules and data caching, ensuring that data loss or processing delays do not occur even under high data traffic conditions. In addition, the module is equipped with multiple communication interfaces, including Ethernet interfaces, serial ports, etc., to facilitate connection with different devices and networks.
Core functions
Network data processing: The INNIS01 module can efficiently process various types of data in industrial networks, whether it is real-time process data, equipment status information, or control instructions, it can be quickly and accurately parsed and forwarded. In industrial automation production lines, it can quickly transmit real-time data collected by sensors to the control system, and at the same time send instructions issued by the control system to the executing agencies in a timely manner, ensuring the smooth operation of the production process.
Protocol conversion: Supports multiple industrial communication protocols, such as Modbus, Profibus, Ethernet/IP, etc. In practical industrial scenarios, devices from different manufacturers may use different communication protocols, and the INNIS01 module can achieve the conversion between these protocols, enabling seamless communication between different devices. For example, in a factory workshop containing multiple branded devices, this module can connect and exchange data between devices using Profibus protocol and systems using Ethernet/IP protocol, breaking down communication barriers between devices.
Network management and diagnosis: With powerful network management functions, it can monitor and manage devices in the network in real-time, including device status monitoring, network topology discovery, etc. When a network failure occurs, the module can quickly locate the fault point and send alarm messages through indicator lights or network management software to help technicians troubleshoot and solve problems in a timely manner, reducing system downtime.
NFI-NET is a unidirectional, high-speed serial data highway shared by all INFI 90 OPEN nodes. INFI-NET provides sophisti cated interfaces for data exchange.
This process control unit interface is made up of state-of-the-art INFI 90 OPEN modules.
INTENDED USER
Personnel installing, operating or maintaining the process control unit interface should read this instruction before performing any installation, operation or maintenance procedures.
Installation requires an engineer or technician with experience handling electronic circuitry and who is familiar with commu nication networks.
PROCESS CONTROL UNIT INTERFACE DESCRIPTION
The process control unit interface is made up of the INNIS01 Network Interface Slave Module (NIS) and INNPM11 Network
Processing Module (NPM). Through this interface the process control unit has access to INFI-NET. At the same time the NPM module communicates with the control modules via the Controlway.
The process control unit interface can support hardware redundancy (refer to Figure 1-1). In a redundant configuration,there are two NIS modules and two NPM modules. One pair of modules is the primary. If the primary modules fail, the backup modules come on-line. Redundant data highway com munication capability is a standard feature.
INNIS01 NETWORK INTERFACE SLAVE MODULE
The NIS module is an I/O module that works in conjunction with the NPM module. This allows a node to communicate with any other node on the INFI-NET loop.
The NIS module is a single printed circuit board that occupies one slot in the module mounting unit. The circuit board con tains microprocessor based communication circuitry that enables it to interface with the NPM module.
Two latching screws on the faceplate secure the NIS module to
the module mounting unit. There are 16 LEDs on the faceplate
that display error codes and event/error counts.
The NPM module acts as a translator between INFI-NET and Controlway. The NPM module holds the process control unit database and directs the communication process between the modules residing on Controlway and the NIS module.
The NPM module is a single printed circuit board that occupies the slot adjacent to the NIS module in the module mounting unit.
The circuit board contains microprocessor based commu nication circuitry that enables it to interface with the NIS module and all Controlway modules.
Two latching screws on the NPM module faceplate secure the module in the module mounting unit. The faceplate contains eight CPU LEDs, a status LED, and a stop/reset pushbutton.
The NPM module has three card edge connectors for external signals and power (P1, P2 and P3). Connector P1 connects to common (ground), +5 VDC power, and the Controlway. Connector P2 connects the NPM module to the NIS module.
Connector P3 provides for communication between primary and backup process control unit interfaces.
The NPM module communicates with the NIS module within its process control unit through the I/O expander bus.
