The S7 brings to the user a powerful solution to a host of
control applications, which is easy to adapt and expand the system. The S7 is a
family of PLCs which allows the user to tailor their selection of components
which best suits their requirements, and is the long term successor to the
highly successful S5 range. Whatever the S5 can do, the S7 can do more quickly
and more easily. The 3rd generation of S7-200 now builds on the success of the
original range and exploits new CPU's in order to produce even faster and more
powerful range of PLC's. The range of CPU's available has been increased with
the introduction of the new 224XP, as has the range of digital, analogue and
communications expansion modules. For the faster type of application real time
control is easily achieved by use of the comprehensive range of built-in
interrupts. Timed, Communication, High Speed Counter, High Speed Pulse Output,
and hardware interrupts are all available, and the implementation of a priority
table means that all the interrupts can work simultaneously. Communications
with S7-200 is built in. Inter PLC communications is achieved using two wire
network which can be up to 1200 meters and can have up to 126 nodes. In
"Freeport" mode the PLC's RS-485 port runs in free ASC11 mode making
it possible to communicate with other devices. In line with Siemens objective
to make the programming of S7-200 as user friendly as possible MicroWin
programming software has been further improved. These improvements all help
minimise program development time. This has been achieved by including more and
improving existing "wizards". These help program developers with the
more routine/complex parts of their programs, e.g. TD200 configuration, PID
loop configuration, High Speed Counter configuration, etc. Inclusion of context
sensitive help also means that all the information required is at the users
fingertips.
