MVME332XT工控机器人备件
9-30 DriveWindow 2注意，离线项目、故障和事件的质量在更新之前不会改变。从2.10版（包括在DriveWindow 2.40版中）开始，DriveOPC还可以处理Windows 2000/XP/Vista/7/8下的NETA-21 DDCS网关。从2.10版开始（包括在DriveWindow 2.40版本中），DriveOPC的最大通道数已从10个增加到1000个。如果使用DriveDA OPC服务器进行连接，则本机DriveDA驱动器（ACS880系列）将再增加1000个通道。因此，信道总数（2000），即数字板和设备，实际上是无限的。在32位版本的Windows 2000、Windows XP、Windows Vista、Windows 7和Windows 8下，通信板/设备可以是：•RUSB-02 USB/DDS适配器。它们有一个DDCS光信道。•NDPA-02板，类型为PC卡（PCMCIA）。它们有一个DDCS光信道。•NETA-21远程监控设备，即具有以太网连接的设备。它们有一个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适配器。它们有一个DDCS光信道。•NETA-21远程监控设备，即具有以太网连接的设备。它们有一个DDCS光信道。4.1.2最大信道数DriveWindow不使用通信信道本身。因此，限制由DriveOPC设置，DriveWindow使用DriveOPC与驱动器通信。从2.03版（包括在DriveWindow 2.02版中）开始，DriveOPC可以处理多个DDCS通信设备。从2.10版（包括在DriveWindow 2.40版中）开始，DriveOPC在Windows 2000/XP/Vista/7/8下最多支持1000个通道。如果使用DriveDA（不包括在DriveWindows中），则本机DriveDA支持额外的1000个通道，因此总的最大值（2000）为2000。4.1.3驱动器的最大数量限制由DriveOPC设置，DriveWindow使用DriveOPC与驱动器通信。通信信道的节点地址空间为256。杂项9-32 DriveWindow 2其中两个由DDCS协议保留。通信库为分支单元保留了另外50个节点地址（76…125）。此外，我们建议将节点地址保留为一，以备备件使用。因此，每个通信信道可以连接203个驱动器（外加一个备用驱动器）。在Windows 2000/XP/Vista/7/8下，支持203000个驱动器（外加1000个备件）。但是，电脑的速度或远程使用DriveOPC可能会带来一些限制。例如，在线刷新驱动器状态可能会在达到理论最大值之前很长时间阻塞您的电脑。4.1.4监测最大监测项目数：6。最小绘图间隔：快速模式下为1ms，正常模式下为10ms。注意，如果可能，该间隔用作测量周期时间。然而，具有短的间隔和多个通道来监控会减慢测量周期。在快速模式下，从驱动器读取一个值需要大约1毫秒。在正常模式下，从驱动器读取一个值需要3…4毫秒。只有当您的电脑中没有其他负载（包括设备驱动程序），并且您的电脑及其显示驱动程序足够快时，这些选项才有效。历史缓冲区的最大大小：2147483647毫秒（几乎25天）。请注意，实际上，电脑的（虚拟）内存大小设置了历史缓冲区大小的上限。y轴最小值和最大值的最大绝对值：3.40282356779733642751e+038。x轴的最大长度：32700*间隔。注意，在实践中，x轴的长度不应超过屏幕上水平点的长度。在监控过程中更新屏幕会变慢，您需要更新的点数越多。
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.
