The VMIVME-7750 has an on-board BIOS Setup program that controls many configuration options. These options are saved in a special non-volatile, battery-backed memory chip and are collectively referred to as the board’s ‘CMOS Configuration’. The CMOS configuration controls many details concerning the behavior of the hardware from the moment power is applied. The VMIVME-7750 is shipped from the factory with hard drive type configuration set to AUTO in the CMOS. Details of the VMIVME-7750 BIOS setup program are included in Appendix C.

The VMIVME-7750 provides rear I/O support for the following: PMC, IDE drive and floppy drive. These signals are accessed by the use of a rear-panel transition board such as the VMIACC-0562, which terminate into industry standard connectors. The front panel connectors, including connector pinouts and orientation, for the VMIVME-7750 are defined in Appendix A. Rear panel connections are defined in the appropiate rear panel transition utility board Installation Guide. See the VMIVME-7750 product specification for compatible rear panel transistion utility boards offered by VMIC.

The VMIVME-7750 provides Synchronous DRAM (SDRAM) as on-board system memory. Memory can be accessed as bytes, words or longwords. The VMIVME-7750 accepts one 144-pin SDRAM SODIMM for a maximum capacity of 512 Mbytes. The on-board DRAM is dual-ported to the VME bus through the PCI-to-VME bridge and is addressable by the local processor, as well as the VMEbus slave interface by another VMEbus master. Caution must be used when sharing memory between the local processor and the VMEbus to prevent a VMEbus master from overwriting the local processor’s operating system.

DCS has entered the fourth generation
Affected by the development of information technology (such as network communication technology, computer hardware technology, embedded system technology, fieldbus technology, various configuration software technologies, database technology, etc.), as well as the increasing demand for advanced control and management functions from users, various DCS manufacturers (represented by Honeywell, Emerson, Foxboro, Yokogawa, ABB) have successively improved the technical level of DCS systems and continuously enriched their content. It can be said that a new generation of DCS marked by Honeywell’s latest ExperionPKS (Process Knowledge System), Emerson’s PlantWeb (EmersonProcess Management), Foxboro’s A2, Yokogawa’s R3 (PRM Plant Resource Management System), and ABB’s IndustrialIT system has been formed.

If we consider Foxboro’s I/ASeries back then as a milestone in the third generation DCS system, then the latest DCS of the above companies can be classified as the fourth generation. The main symbol of the fourth generation DCS is the two words starting with “I”: Information and Integration.

Technical characteristics of the fourth generation DCS
The architecture of the fourth generation DCS is mainly divided into four layers: on-site instrument layer, control device unit layer, factory (workshop) layer, and enterprise management layer. Generally, DCS manufacturers mainly provide three layers of functionality in addition to the enterprise management layer, while the enterprise management layer connects to third-party management software platforms (ERP, CRM, SCM, etc.) by providing open database interfaces. So, today’s DCS mainly provides all control and management functions at the factory (workshop) level, and integrates information management functions across the entire enterprise.

DCS fully embodies informatization and integration
Information and integration basically describe the changes that are happening in DCS systems today. Users can already collect information and data from the entire factory workshop and process, but they hope that this large amount of data can be reflected in an appropriate way and help the decision-making process, so that users can obtain the truly needed data in a convenient place in a way they understand.
Informationization is reflected in the fact that each DCS system is no longer a control system primarily focused on control functions, but a comprehensive platform system that fully utilizes information management functions. DCS provides the entire information channel from site to equipment, from equipment to workshop, from workshop to factory, and from factory to enterprise group. These information fully reflect comprehensiveness, accuracy, real-time, and systematicity.
