SIEMENS Digital Output Module 6ES5441-8MA11

Product Description:

The Simatic S5 PLC is an automation system based on Programmable Logic Controllers.  Such automation systems control process equipment and machinery used in manufacturing. S5 PLC still has a huge installation base in factories around the world. Most automation systems integrators still have the ability to provide support for the platform.

Hardware:

The S5 line comes in the 90U, 95U, 101U, 100U, 105, 110, 115, 135U, and 155U chassis styles. Higher the number(except for the 101U), the more sophisticated and more expensive the system. Within each chassis style, several CPUs are available, with varying speed, memory, and capabilities. Some systems provide redundant CPU operation for ultra-high-reliability control, as used in pharmaceutical manufacturing, for example.

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.

Software:

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.

The original Step 5 versions ran on the CPM operating system. Later versions ran on MS-DOS, and then versions of Windows through Windows XP. The final version of Step 5 is version 7.2. 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 than Step5. One allows Step5 programs to be cross-compiled to and from the C programming language and BASIC.

Blocks:

Five types of blocks are available:

Organization blocks (OB) - for managing the control program

Programming blocks (PB) - contain the control program structured according to functional or process-oriented characteristics

Sequence blocks (SB) - for programming sequential controls

Function blocks (FB) - contain frequently occurring and particularly complex program parts

Data blocks (DB) - for storing data required for processing the control program.

Some S5 PLCs also have block types FX (Extended Function Blocks), and DX(Extended Data Blocks); these are not distinct block types, but rather are another set of available blocks due to the CPU having more memory and addressing space.

Additional functions:

Saving user-specific project settings

Symbol editor

Automatic generation and updating of cross-reference lists

Comparison of user programs

Transferring blocks to EPROM and EEPROM memory modules for programmable controllers

Rewiring inputs, outputs, flags, timers and counters

Testing and service functions for startup and maintenance
