The VMIVME-7750 provides high-performance video, Ultra ATA storage device control and Local Area Network (LAN) access by means of on-board PCI-based adapters and associated software drivers. High-performance video and Ultra ATA storage device control are provided by the embedded Intel 815E chipset. Dual high-performance LAN operation is provided by an Intel GD82559ER Fast Ethernet adapter chip (LAN1) and the embedded Intel 815E chipset (LAN2). The two LAN adapters can be configured to allow the VMIVME-7750 to access two separate, physical networks. Each LAN adapter is capable of running 10BaseT and 100BaseTx.

To optimize performance of each of these PCI-based subsystems, the user must install the driver software located on the distribution CD-ROM provided with the unit. Detailed instructions for installation of the drivers during the installation of Microsoft Windows 98 Second Edition (SE), Windows NT Workstation (NTW) 4.0 and Windows 2000 Professional operating systems are provided in the following sections.

The use of a USB keyboard/mouse with an operating system that supports USB devices requires changing the default BIOS settings before and after the installation of Windows 98SE/2000. ‘Legacy USB Support’ must be enabled in the BIOS to allow a USB keyboard/mouse to operate as a PS/2 device during the installation of Windows 98SE/2000. After the installation is complete, the computer will restart and boot Windows 98SE/2000. As the computer is restarting to boot the operating system for the first time, ‘Legacy USB Support’ must be disabled, and ‘Assign Interrupt to USB’ must be enabled. If Legacy USB Support is not disabled, Windows 98SE/2000 will attempt to load a device driver for a device (USB) that is not present at that point. See “BIOS Setup” on page 87 for guidelines on changing BIOS settings.

A suggested workaround to this situation is to connect a PS/2 keyboard and mouse, disable ‘Legacy USB Support’ and enable ‘Assign Interrupt to USB’ in the BIOS, and install Windows 98SE/2000. At some point after the installation is complete, replace the PS/2 keyboard and mouse with a USB keyboard and mouse and enable ‘Legacy USB Support’ in the BIOS. This approach might be easier since you don’t have to worry about making changes to the BIOS at exactly the right time.

Since the introduction of DCS in 1975, there have been about three major changes. In the 1970s, the hardware, operating system, and monitoring software of the operating station were all dedicated and developed by various DCS manufacturers themselves, and there was no dynamic flowchart. The communication network was basically in a polling mode; In the 1980s, it was different, as communication networks often used token methods; In the 1990s, universal systems emerged for operating stations, and in the late 1990s, some communication networks followed the TCP/IP protocol, while others began using Ethernet. Overall, the changes are mainly reflected in the I/O board, operating station, and communication network. The controller changes relatively less. The operation station mainly manifests in the application of changing from specialized computers to general-purpose computers, such as PCs and small computers. However, currently its operating system generally uses UNIX, and there are also small systems that use NT. Compared to UNIX, its stability is better, while NT may experience crashes. The I/O board is mainly reflected in the introduction of the fieldbus into the DCS system.

The DCS system consists of three major parts: a controller with I/O components, a communication network, and a human-machine interface. The human-machine interface includes an operation station, an engineer station, and a history station. The controller I/O components are connected to the production process, the operation station is connected to people, and the communication network connects these two parts into a system. So the operation station is an important component of DCS. The engineer station configures the controller and operation station, and the historical station records the historical data of the production process. The human-machine interface developed in recent years also includes dynamic data servers.

A DCS system controller and I/O components can usually run for 16 to 20 years, while the operating station is more prone to damage due to active components, such as hard drives, keyboards, CRTs, floppy drives, etc. After 6 to 8 years of operation, the probability of failure is relatively high. Therefore, during the operation of DCS, there are more updates to the operating station.

The changes in the controller of DCS are relatively small. The changes are manifested in the arrangement of control algorithms, the number of control algorithms, the number of I/O points accessed, and the size of memory. The operating system is generally dedicated. The changes in operating stations have been significant. Before the 1980s, operating stations generally did not have hard drives or dynamic flow charts, and the number of labels displayed was relatively small, such as 500 labels (labels refer to the logical relationships of AI, DI, circuits, and switching values). In the 1980s, operating stations appeared that could display 5000 labels, and in the 1990s, operating stations appeared that could display 30000 labels. At the same time, there have also been general display software running on Microsoft’s NT general platform. At first, general software was only used on PLC operation stations, and later gradually applied to DCS. Its label quantity can reach 10000 or even more.
