8102-HO-IP Fast Serial Data Bus Module

Description

NovaTech 8000 series I/O is D/3 ® The latest remote I/O series for distributed control systems (DCS). It is the preferred I/O for new installations and can replace the old NovaTech 16000 series I/O in the existing PCM cabinet, using existing field wiring to connect to a new terminal panel with existing connectors. It also replaces Quantum I/O. The NovaTech 8000 series I/O has a temperature range of -40 ° C to+70 ° C and a G3 corrosive coating, making it an I/O system designed specifically for on-site installation. It is connected to traditional and intelligent field devices through multi-channel I/O modules. The module communicates with the redundant Ethernet Bus Interface Module (EBIM) through a fast internal bus, which provides dual redundant high-speed Ethernet data connection for the D/3. A single 8000 series node can support up to 64 I/O modules, each with 4 to 32 channels.

The PCM EthernetMPC2 card can support up to 50 nodes. With the availability of Intrinsically Safe (IS) modules, the 8000 series I/O provides a solution for general and hazardous area applications, even within the same node. When used with PCM 4100, PCM 4200, or PCI based PCM, the 8000 series I/O requires Ethernet Multi Protocol Controller 2 (EthernetMPC2) cards and D/3 12.2 or higher. When used with PCM 5 and D/3 versions 16.0 or higher, the EthernetMPC2 card is not required.

In many fields of automation, the requirements for effectiveness are becoming increasingly high, resulting in higher requirements for the fault tolerance level of automation systems, especially in situations where equipment downtime costs are very high. In order to meet these strict requirements, redundant technology is usually used in DCS systems to meet the standards of safety, reliability, and effectiveness required in these fields.

In the DCS control system, the distributed processing unit is a key part of the system. The current controllers of these distributed processing units are often built on the 86 series CPU, and this architecture is currently widely adopted. However, due to the characteristics of the 86 series distributed processing units, the current controller processing units have many drawbacks, such as high heat release. And in a closed environment, these problems are always difficult to solve. With the development of many low-power technologies and the emergence of low-power controllers, CPUs with distributed processing units can have more choices, especially low-power controllers that generate less heat and can improve system integration.

Regardless of the significant differences between domestic and foreign DCS control systems, redundant technology is widely adopted in these DCS control systems. The DCS control system mainly adopts network redundancy technology, distributed processing unit redundancy technology, IO card redundancy technology, power redundancy technology, etc.
