9-30 DriveWindow 2注意，離線(xiàn)項目、故障和事件的質(zhì)量在更新之前不會(huì )改變。從2.10版（包括在DriveWindow 2.40版中）開(kāi)始，DriveOPC還可以處理Windows 2000/XP/Vista/7/8下的NETA-21 DDCS網(wǎng)關(guān)。從2.10版開(kāi)始（包括在DriveWindow 2.40版本中），DriveOPC的最大通道數已從10個(gè)增加到1000個(gè)。如果使用DriveDA OPC服務(wù)器進(jìn)行連接，則本機DriveDA驅動(dòng)器（ACS880系列）將再增加1000個(gè)通道。因此，信道總數（2000），即數字板和設備，實(shí)際上是無(wú)限的。在32位版本的Windows 2000、Windows XP、Windows Vista、Windows 7和Windows 8下，通信板/設備可以是：?RUSB-02 USB/DDS適配器。它們有一個(gè)DDCS光信道。?NDPA-02板，類(lèi)型為PC卡（PCMCIA）。它們有一個(gè)DDCS光信道。?NETA-21遠程監控設備，即具有以太網(wǎng)連接的設備。它們有一個(gè)DDCS光信道。在64位版本的Windows Vista和Windows 7下，通信板可以是：?RUSB-02 USB/DDS適配器。它們有一個(gè)DDCS光信道。?NETA-21遠程監控設備，即具有以太網(wǎng)連接的設備。它們有一個(gè)DDCS光信道。4.1.2最大信道數DriveWindow不使用通信信道本身。因此，限制由DriveOPC設置，DriveWindow使用DriveOPC與驅動(dòng)器通信。從2.03版（包括在DriveWindow 2.02版中）開(kāi)始，DriveOPC可以處理多個(gè)DDCS通信設備。從2.10版（包括在DriveWindow 2.40版中）開(kāi)始，DriveOPC在Windows 2000/XP/Vista/7/8下最多支持1000個(gè)通道。如果使用DriveDA（不包括在DriveWindows中），則本機DriveDA支持額外的1000個(gè)通道，因此總的最大值（2000）為2000。4.1.3驅動(dòng)器的最大數量限制由DriveOPC設置，DriveWindow使用DriveOPC與驅動(dòng)器通信。通信信道的節點(diǎn)地址空間為256。雜項9-32 DriveWindow 2其中兩個(gè)由DDCS協(xié)議保留。通信庫為分支單元保留了另外50個(gè)節點(diǎn)地址（76…125）。此外，我們建議將節點(diǎn)地址保留為一，以備備件使用。因此，每個(gè)通信信道可以連接203個(gè)驅動(dòng)器（外加一個(gè)備用驅動(dòng)器）。在Windows 2000/XP/Vista/7/8下，支持203000個(gè)驅動(dòng)器（外加1000個(gè)備件）。但是，電腦的速度或遠程使用DriveOPC可能會(huì )帶來(lái)一些限制。例如，在線(xiàn)刷新驅動(dòng)器狀態(tài)可能會(huì )在達到理論最大值之前很長(cháng)時(shí)間阻塞您的電腦。4.1.4監測最大監測項目數：6。最小繪圖間隔：快速模式下為1ms，正常模式下為10ms。注意，如果可能，該間隔用作測量周期時(shí)間。然而，具有短的間隔和多個(gè)通道來(lái)監控會(huì )減慢測量周期。在快速模式下，從驅動(dòng)器讀取一個(gè)值需要大約1毫秒。在正常模式下，從驅動(dòng)器讀取一個(gè)值需要3…4毫秒。只有當您的電腦中沒(méi)有其他負載（包括設備驅動(dòng)程序），并且您的電腦及其顯示驅動(dòng)程序足夠快時(shí)，這些選項才有效。歷史緩沖區的最大大?。?147483647毫秒（幾乎25天）。請注意，實(shí)際上，電腦的（虛擬）內存大小設置了歷史緩沖區大小的上限。y軸最小值和最大值的最大絕對值：3.40282356779733642751e+038。x軸的最大長(cháng)度：32700*間隔。注意，在實(shí)踐中，x軸的長(cháng)度不應超過(guò)屏幕上水平點(diǎn)的長(cháng)度。在監控過(guò)程中更新屏幕會(huì )變慢，您需要更新的點(diǎn)數越多。
9-30 DriveWindow 2 Note that qualities of off-line items, faults, and events do not change until you update them. Since version 2.10 (included in DriveWindow version 2.40), DriveOPC can handle also NETA-21 DDCS gateway under Windows 2000/XP/Vista/7/8. Since version 2.10 (included in DriveWindow version 2.40), DriveOPC the maximum number of channels has been increased from 10 to 1000. If connection is made using the DriveDA OPC sever, native DriveDA drives (ACS880 family) add another 1000 channels. So the total number of channels (2000), i.e. number boards and devices, is practically unlimited. Under 32-bit versions of Windows 2000, Windows XP, Windows Vista, Windows 7, and Windows 8 the communication boards/devices can be: ? RUSB-02 USB/DDCS adapters. They have one DDCS optical channel. ? NDPA-02 boards, which are of type PC Card (PCMCIA). They have one DDCS optical channel. ? NETA-21 remote monitoring devices, which are devices with Ethernet connection. They have one DDCS optical channel. Under 64-bit versions of Windows Vista and Windows 7 the communication boards can be: ? RUSB-02 USB/DDCS adapters. They have one DDCS optical channel. ? NETA-21 remote monitoring devices, which are devices with Ethernet connection. They have one DDCS optical channel. 4.1.2 Maximum Number of Channels DriveWindow does not use the communication channels itself. So, the limits are set by the DriveOPC, which DriveWindow uses in communication with the drives. Since version 2.03 (included in DriveWindow version 2.02), DriveOPC can handle several DDCS communication devices. Since version 2.10 (included in DriveWindow version 2.40), DriveOPC supports maximum 1000 channels under Windows 2000/XP/Vista/7/8. Native DriveDA supports additional 1000 channels, so the total maximum (2000) is 2000, if DriveDA (not included in DriveWindow) is used. 4.1.3 Maximum Number of Drives The limits are set by the DriveOPC, which DriveWindow uses in communication with the drives. The node address space of a communication channel is 256. Miscellaneous 9-32 DriveWindow 2 Two of these are reserved by the DDCS protocol. Additional 50 of the node addresses (76...125) are reserved for branching units by the communication library. Also, we recommend to leave the node address one for spare parts. Thus, each communication channel can connect 203 drives (plus one spare). Under Windows 2000/XP/Vista/7/8, 203000 drives (plus 1000 spares) are supported. However, there can be limitations introduced by the speed of your PC or using DriveOPC remotely. It may be that having drive status refreshing on-line, for example, chokes you PC long before the theoretical maximum is reached. 4.1.4 Monitoring Maximum number of monitored items: 6. Minimum drawing interval: 1 ms in fast mode, 10 ms in normal mode. Note that the interval is used as a measurement cycle time, if possible. However, having a short interval and many channels to monitor slows down the measurement cycle. In fast mode it takes about 1 ms to read one value from a drive. In normal mode it takes 3...4 ms to read one value from a drive. These are valid only if there is no other load (including device drivers) in your PC, and your PC and its display driver are fast enough. Maximum size of the history buffer: 2147483647 ms (almost 25 days). Note that in practice the size of the (virtual) memory of your PC sets the upper limit for the size of the history buffer. Maximum absolute value of yaxis minimum and maximum: 3.40282356779733642751e+038. Maximum length of the x-axis: 32700 * interval. Note that in practice you should not have longer x-axis than you have horizontal point on your screen. Updating the screen during monitoring gets slower, the more you have points to update.
