西门子操作员面板6AV6643-0AA01-1AX0

当 PC 位于与操作员面板隔开的安全、带有空调设备的机房中时，借助于 KVM 扩展器，操作人员可以从控制室操作和监测过程。由于 PC 是分开安装的，因此，由 IT 管理员执行维护工作可在技术室中集中完成。另一个优点：由操作人员在控制室中完成的工作不会受到干扰或因检修而中断。

因此可实现集中式工作，不会听到风扇噪音和感觉到 PC 散发的热量。

KVM 扩展器 DP1.2-Vision，发射器（底部）和接收器（顶部）

KVM 扩展器 DVI‑Vision-CAT/Fiber、CATVision、DP‑Vision、DP1.2‑Vision 和 DP1.2‑VisionXG 各包含台式或 19 英寸设计形式的发送器和接收器，通过 CAT 电缆 (5/6/7) 或光纤电缆相互连接在一起。这些扩展器独立于系统平台和操作系统。可以在发射器和接收器处建立操作员站（用于直接在计算机上进行维护的本地控制台）。

DP1.2‑VisionXGs 具有冗余电源。其它 KVM 扩展器也可配有冗余电源。如果电源出现故障，冗余电源会立即接通，从而与计算机之间的连接不会中断。

标准接口用于连接计算机。无需进行软件设置和计算机调整。

DP1.2 Vision、DP Vision 和 DVI Vision 具有一个网络接口，DP1.2 VisionXG 具有两个网络接口（用于 Web 界面和监视功能）。可通过 Web 界面进行简单配置并监视和报告监控值。

KVM 扩展器 DL Vision、DL Vision DP、DVI Vision-CAT/Fiber 和 DP Vision 具有屏幕冻结功能。如果监视器丢失视频信号或远程计算机的图形控制器出现问题，在画面冻结功能会固定在Zui后显示的图像上。

所有 KVM 扩展器都支持包含 2 个或Zui多 4 个视频信号的多通道操作。根据计算机的具体多显示器图形卡和所选的 KVM 扩展器，可实现带有Zui多 4 个屏幕的多显示器操作员站。

借助于 KVM 交换机，可在控制室中由管理员集中完成本地维护。

SINAMICS Drive Control Chart (SINAMICS DCC) expands the scope of device functions by means of freely available closed-loop control, arithmetic and logic blocks and offers a means by which proprietary technological functions can be graphically configured in the SINAMICS drive system. In addition, local data processing in the drive supports the implementation of modular machine concepts and results in an increase in the overall machine performance. SINAMICS DCC is a part of the Advanced Technology Function, and is installed as an add-on to the STARTER commissioning tool.

SINAMICS DCC provides users with greater integral scope to adapt systems to the specific functions of their machines. SINAMICS DCC does not limit the number of functions that can be used. The number of functions is limited only by the performance capability of the Control Unit.

SINAMICS DCC is available for the following SINAMICS drive systems:

The user-friendly DCC editor enables easy graphics-based configuration, allows control loop structures to be clearly represented and provides a high degree of reusability of diagrams that have already been created.

The open-loop and closed-loop control functions are defined by using multi-instance-capable blocks (Drive Control Blocks (DCBs)) from a library (DCB library) that are selected and graphically linked with one another by dragging and dropping. Test and diagnostic functions allow the program behavior to be verified and, in the case of a fault, the cause identified.

Two types of DCB library are available, i.e. DCB Standard and DCB Extension. The DCB Standard library supplied with SINAMICS DCC contains a large selection of closed
