To maintain maximum transparency, STEP 5 offers a number of structuring facilities: A STEP 5 program may, therefore, contain thousands of statements. STEP 5 allowed the creation of structured or unstructured programming, from simple AND/OR operations up to complex subroutines. One allowed STEP 5 programs to be cross-compiled to and from the CВ programming language andВ BASIC. Most closely emulated STEP 5, some adding macros and other minor enhancements, others functioning drastically differently from STEP 5. Several third-party programming environments were released for the S5.

It simulates aВ State machineВ on the S5 platform.

Graph5 is a sequentialВ programming languageВ intended for use on machines that normally run through a series of discrete steps. In addition to STEP 5, Siemens offered a proprietaryВ State logicВ programming package called Graph5. The final version of STEP 5 was version 7.2 (upgradable to version 7.23 Hotfix 1 with patches).

Later versions ran onВ MS-DOS, and then versions of Windows throughВ Windows XP. The original STEP 5 versions ran on theВ CP/M operating system. STEP 5 was used for programming, testing, and commissioning, and for documentation of programs for S5 PLCs.

The S5 product line was usually programmed with a PC based software programming tool called STEP 5.

The Simatic S7 product line is programmed in STEP 7 (also known as TIA Portal).

The Simatic S5 product line is programmed in STEP 5.

Programs running on Simatic devices run in software environments created by Siemens. These models were later succeeded by the S7-1200 and S7-1500 series. The first entries in the S7 line were the S7-200, S7-300 and S7-400 series.

Available options included serial and Ethernet communications, digital input and output cards,В analog signal processingВ boards, counter cards, and other specialized interface and function modules. Some systems provided redundant CPU operation for ultra-high-reliability control, as used inВ pharmaceuticalВ manufacturing, for example.Д®ach chassis consisted of aВ power supply, and a backplane with slots for the addition of various option boards. Within each chassis style, severalВ CPUsВ were available, with varying speed, memory, and capabilities. The higher the number (except for the 101U), the more sophisticated and more expensive the system was. Siemens has developed four product lines to date: For example, the Simatic 505 could handle floating point quantities and trigonometric functions. More complex inputs, outputs, and calculations were also supported as the Simatic line developed.

вЂњLowвЂќ signal: Temperature is within expected limitsД«ased on this input, and other factors, the program on the Simatic device might send a binary output signal to the same machine with the following meanings:.

вЂњHighвЂќ signal: Temperature exceeded an operating limit.

For example, a binary input going from a thermometer on a machine to a Simatic device might have the following meanings: The programs on the Simatic devices respond inВ real timeВ to inputs fromВ sensorsВ on the controlled machines, and send output signals toВ actuatorsВ on the machines that directing their subsequent operation.Дepending on the device and its connection modules, signals may be a simple binary value ('high' or 'low') or more complex. Microprocessors were introduced in 1973, allowing programs similar to those on general-purpose digital computers to be stored and used for machine control.В Simatic devices have input and output modules to connect with controlled machines. Early Simatic devices were transistor-based, intended to replace relays attached and customized to a specific machine. Siemens Simatic S7-300 PLC CPU with three I/O modules attachedДЄs with otherВ programmable logic controllers, Simatic devices are intended to separate the control of a machine from the machine's direct operation, in a more lightweight and versatile manner than controls hard-wired for a specific machine.
