Woodward understands the time-intensive nature of Power Generation projects. Ensuring the longevity of components is one way we can make our customers successful. Woodward has supplied and supported the well-established SPM-D line of synchronizers for 20+ years. With the state of the art Drop-In replacement successor, SPM-D2 the life of this synchronizer line is now extended. All of the SPM-D2 synchronizers are password protected and are configurable either through HMI as before or through ToolKit configuration tool with USB connectivity.

From the working principle of PLC, the input and output of PLC are physically separated from each other, and the connection between them is achieved by running programs stored in its memory. Its input and output are related, not through physical processes or circuits; Instead, it relies on information processes and soft logical connections. Its working foundation is to make good use of information. Information, unlike matter and energy, has its own laws. Information is easy to process, transmit, and store; Information can also be reused, and so on. It is precisely because of these characteristics of information that the basic characteristics of PLC are determined.

The following is an introduction to the four characteristics of PLC: 2.1 Rich functions. PLC has a very rich range of functions. This is mainly related to its rich instruction system for processing information and internal devices for storing information. It has dozens or hundreds of instructions, which can handle various logical problems and perform various types of data operations. Anything that an ordinary computer can do, it can also do it. Its internal devices, namely the data storage area in memory, have a wide variety of types and large capacity. I/O relays can be used to store input and output point information, ranging from tens or hundreds to thousands, tens of thousands, or even tens of thousands. This means that it can perform input and output information transformation at so many I/O points for such large-scale control. Its internal relays are equivalent to intermediate relays, with a larger number. One bit in memory can serve as an intermediate relay, why not many! It also has many counters and timers, which are beyond the reach of relay circuits. A small box or module with internal timers and counters that can reach hundreds or thousands.

This is also because as long as a word in memory is used and some flag bits are added, it can become a timer or counter, which is why there are so many. Moreover, these internal devices can also be set to maintain power loss or not maintain power loss, that is, reset after power on. To meet different usage requirements. These are also difficult for relay components to achieve. Its data storage area can also be used to store a large amount of data, and information of hundreds, thousands, or tens of thousands of words can be stored, and it is not lost after power failure.

PLC also has a variety of external devices, which can establish a friendly human-machine interface for information exchange. Can input programs, input data, can read programs, and read data. And when reading and writing, it can be done on a picture and text rich screen. After reading the data, it can be dumped and printed. Data input can be keyed in, read and card in, and so on. The PLC also has a communication interface that can be linked or networked with computers to exchange information. It can also be connected to the internet to form a larger and more geographically diverse control system that a single machine cannot have.

PLC also has powerful self checking function, which can perform self diagnosis. The results can be automatically recorded. This adds transparency and convenience to its maintenance. The rich functions provide the possibility for the widespread application of PLC; At the same time, it has also created conditions for the automation, telecontrol, and intelligent control of industrial systems. PLC, which integrates rich functions, is not found in other electrical controllers; It is even more incomparable to traditional relay control circuits.
