It was manufactured and sold by Siemens AG. The S5 line comes in the 90U, 95U, 101U, 100U, 105, 110, 115,115U, 135U, and 155U chassis styles. Within each chassis style, several CPUs are available, with varying speed, memory, and capabilities. Each chassis consists of a power supply, and a backplane with slots for the addition of various option boards. Available options include serial and Ethernet communications, digital input and output cards, analog signal processing boards, counter cards, and other specialized interface and function modules. The S5 product line is usually programmed with a PC based software programming tool called Step 5. Step 5 is used for programming, testing, and commissioning, and for documentation of programs for S5 PLCs.

Later versions ran on MS-DOS, and then versions of Windows through Windows XP. The final version of Step 5 is version 7. No further development of this product line has occurred since that time, due to its announced obsolescence. In addition to Step5, Siemens offered a proprietary State logic programming package called Graph5.

Graph5 is a sequential programming language intended for use on machines that normally run through a series of discrete steps. It simulates a State machine on the S5 platform. Several third-party programming environments have been released for the S5. Most closely emulate Step5, some adding macros and other minor enhancements, others functioning drastically differently from Step5. One allows Step5 programs to be cross-compiled to and from the C programming language and BASIC. OR operations up to complex subroutines. A STEP 5 program may, therefore, contain thousands of statements.

Block technique – A linear operation sequence is divided into sections and packed into individual blocks. Segments – Within blocks, fine structuring is possible by programming subtasks in individual segments. Comments – Both a complete program as well as individual blocks or segments and individual statements can be directly provided with comments. The program consists of a sequence of mnemonic codes of the commands executed one after another by the PLC. Absolute or symbolic designations can be used for operands with all three methods of representation. In LAD and FBD complex functions and function block calls can be entered via function keys.

They are displayed on the screen as graphical symbols. There are several program editors, from either genuine Siemens, or from other suppliers. So, other Supplier start to develop new STEP5 version which can run on Windows XP, or Windows 7. CPU having more memory and addressing space.

These can be performed in all three representations. These can only be executed in STL. Please enable javascript or update your browser. Please enable javascript or update your browser.
