Siemens S5 and S7 PLCs

Which Siemens PLCs can you program?	All of them (see below)
S7-200	Shoebox PLC (programmed windows, the software is very much like the old TI) suitable for small applications. Remarkably cheap operator panels also available. Software is oddly incompatible with the 300/400 series!
S7 300	Replacement for S5 series - New PLC programmed in Windows (and the software is actually quite good! - though very slow with large programs). Software (mostly) compatible with 400 series (but not the 200!).
S7 400	Replacement for S5 series -New PLC programmed in Windows (and the software is actually quite good!). Software compatible with 300 series (but not the 200!).
Siemens S5 90	Small Shoebox PLC, cheap and cheerful
Siemens S5 95	Small Shoebox PLC, EEPROM backup on board, encoders on board, lots of memory, very good PLC (better than the 100 series up to at least the 102)
Siemens S5 100	Small Shoebox PLC, very limited but cheap
Siemens S5 101	(Now discontinued)
Siemens S5 102	Small Shoebox PLC, ladder is still very limited, but has a bit more memoryl
Siemens S5 103	Small Shoebox PLC, the only one in the 100 series which programmers like.
Siemens S5 105	(Now discontinued)
Siemens S5 110	(Now discontinued)
Siemens S5 115	First of the more serious PLCs, powerful but cannot do floating point very well.
Siemens S5 130	(Now discontinued)
Siemens S5 135	Probably the best S5 PLC (unless you need vast amounts of I/O), the first Siemens PLC to do floating point properly.
Siemens S5 150	(Now discontinued)
Siemens S5 155	Previous 'Top of the range' not necessarily the fastest, but the most flexible in terms of I/O

Siemens Graphics Systems

We can convert old WF470 systems to current standards

Which Siemens Graphics Systems can you program?	Most of them, there have been quite a few...
Siemens WF470	(Obsolete) This is a very common character based system. it is complex to program but was one of the first PLC graphics systems to use colour. We have converted many of these to later graphic systems.
COROS	Many different Siemens systems were sold under the COROS label - we can program most of them. Such interfaces inclue the Siemens TD10.
OP TD Protool lite	Text only operator display system, functional but limited for Siemens Touch or button panel, such as OP7, OP17, OP30
Siemens Protool	Reliable, functional units with the somewhat better than usual programming software, for Siemens Touch or button panels such as OP25, OP27, OP35, OP37 and many others.
Siemens Protool Pro	Protool/Pro runs on PC based system (Siemens PC670 or any other PC, preferably (though not always) running Windows NT or 2000) This has Visual BASIC scripting built-in and therefore can replace much larger SCADA systems (within some limitations)
Siemens WinCC	Win CC is a good top-end SCADA system - this has client/server functionality plus web browser and complete redundant systems integration.

Siemens Positioning Modules

Which Siemens Positioning Modules have you used?	Most of them, there have been quite a few...
IP246	(Obsolete) This S5 based system was extensively used in the motor industry
FM350	Encoder position module - incremental encoders both 5V and 24V, SSI absolute encoders
FM351	high precision Servo control module
FM353	high precision Stepper Motor control module
FM354	multi axis servo control module
FM357 and FM357-2	4 axis positioning module - CNC Equivalent for high precision and control by programs
EM253	New Stepper module for the S7-200 series
