Siemens S7-200 base unit – third generation
The S7 brings the user a powerful solution to many control applications, making it easy to adapt and extend the system. The S7 is a family of PLCs that allow users to choose the components they need best suited to their needs, and the long-term successor to the highly successful S5 range. What the S5 can do, the S7 can do faster and more easily. The third generation of the S7-200 now builds on the prosperity of the pristine range and uses more incipient CPUs to build a more expeditious and more potent range of PLC.
In “freeport” mode the PLC’s RS-485 port runs in free ASC11 mode which makes it possible to communicate with other contrivances. Microwine programming software has been further developed to make the S7-200’s programming as user-friendly as possible, in line with Siemens’ objectives. All of these improvements help reduce program development time. This has been achieved through more and improvements to the existing “wizard”.
