伍德沃德 505E 系列数字操控设备的一部分。这些设备是伍德沃德公司制作的 505E 系列的一部分。伍德沃德公司是美国前史悠长的涡轮机操控体系独立制作商之一。505E 系列是为工业规划的蒸汽轮机、小型涡轮发电机或共用涡轮胀大机类型等设备而规划的。505E 系列专为单次抽汽和/或汽轮机进气而规划。它通过运用一对执行器来驱动进口蒸汽阀使汽轮机运转。

505 具有二种工作方式，编程方式(或称组态)和运行方式。所谓组态，即按汽轮机的用意，在选择项目中挑选出需要的内容。组态完后便可进入运行方式来操作汽轮机从起动到停机的整个过程。为了减少将阶跃干扰传入系统的可能性，在505组态完后可移动调节器机壳内的程序跨接器闭锁程序方式的入口通路，这样在汽轮机运行时将不能再使用程序方式。

ADJ(↑)/ADJ(↓)(adjust)在运行方式中增大或减小任一可调参数。

DYN(dynamics ):在运行方式中，调出控制执行机构位置参量的动态设定。

GAIN:在运行方式中，激活被显示动态比例增益设定(必须先按 DYN键，随后再依次作适当的动态校正)。

RST(reset):在运行方式中，激活被显示动态比例增益设定(必须先按 RST

键，随后再依次作适当的动态校正)。

PRG(program):按此健，调节器由CONTROLLING PARAM/PUSH RUNOR PRG)状

态转入程序方式。
RUN:按此健，调节器由CONTROLLING PARAM/PUSH RUN OR PRG)状

态转入运行方式。

STOP:在程序方式中按此键调节器返回到准备就绪状态;在运行方式中，按此键经核实后则引发汽轮机可控停机。

How to choose between PLC and DCS depends on the specific project and plant type. Because of different applications, the requirements of the control system are also different.

In addition to some basic criteria, we must also consider the installation, scalability, maintenance and other factors. Sometimes, one choice is very suitable for a factory, and in another case it may not be. Therefore, the more factors considered in the selection of control system, the more conducive to the realization of short-term and long-term goals.

At present, although PLC system may be the most cost-effective for small equipment, DCS system provides more economical scalability and is more likely to obtain higher initial return on investment.

PLC is suitable for discrete production, generally composed of separate production devices, mainly used to complete the assembly of components, such as labeling, filling or grinding. DCS is suitable for process manufacturing. Automated systems are often used to produce by recipe rather than by piece in a continuous and batch manner. Large scale continuous processing equipment, such as refineries and chemical plants, all use DCS system. Mixed application usually uses PLC and DCS at the same time.

■ process scale:

Small system (<300 i / o points) may have less budget, so plc is more suitable. dcs has a global database, which is easier to manage and upgrade, and can play a more important role in large factory applications.

■ upgrade plan:

PLC system can be selected for small-scale industrial process, but if the process needs to be expanded or upgraded, more PLC hardware and database need to be added, and independent maintenance is needed. This process is time-consuming and laborious, and prone to errors. At this time, DCS is more suitable. As DCS is easier to upgrade, it can also manage users&＃39; trust from the central hub, so it is easier for later maintenance.

Integration requirements:

For stand-alone device, PLC is the ideal choice. When the factory configures multiple PLCs, it will produce the requirement of interconnection. This is generally difficult to implement because it is usually necessary to map data using communication protocols. Especially when the user needs to change, once a PLC system is changed, the two PLCs may not communicate normally. DCS does not need mapping, configuration change is just a simple process, the controller is the system&＃39;s own.
