Micro PLC Engineering that
High-tech in every detail ensures the
outstanding real-time characteristics of our
new CPUs:
• 4 or 6 independent hardware counters
• 4 independent interrupt inputs, with
• 2 high-speed pulse outputs @ 20 kHz
• 2 timed interrupts (adjustable from 1 ms
• High-speed analog inputs – signal
• Real-time clock
1 0
TOP in real time
@ 30 kHz each for interfacing to incre-
mental encoders or high-speed pulse
trains
0.2 ms input filter times to adjust
reaction times – for maximum process
response
each either pulse-width modulation or
pulse train output, e.g. for control of
stepper motors, drives or temperature
in intervals of 1 ms) – for precise control
of processes that change over time

EEPROM cartridge
A small, optional EEPROM cartridge saves
you significant time and money. You can
use it to easily copy, update or replace your
application program on your S7-200 CPU.
And if required, you can mail a program
rapidly and at a low cost to your customers
using this cartridge. Simply turn off the
power, insert the cartridge, and reconnect
the power … and – the user program is up-
dated in a flash.
Battery cartridge
To guarantee that application data are never
lost, the optional battery module permits
long-term backup for typically 200 days
beyond the internal backup of 5 days.
Real-time clock (either built in
or on a cartridge)
Whether you require it to count operating
hours, preheat rooms or provide time
stamps for messages: the real-time clock
of the S7-200 is software-controlled to
provide exact seconds and dates – even
taking leap years into account.
Analog potentiometers
With the S7-200’s analog potentiometers,
you can optimize your process by means
of a screwdriver. You can set memory values,
timer values, counter presets or other
variables without having to intervene in the
program. Very practical, for example, for
modifying a welding time or an overshoot
time rapidly and easily.
Small and practical
Extras
SITOP power –
perfectly matching the S7-200
SITOP power 24 V/3.5 A is the optimum
power supply if connected loads can no
longer be supplied as standard by the
SIMATIC S7-200 CPU: the primary switched-
mode regulator is fully matched to the micro
PLC in design and functionality, and can
be integrated into the PLC network like an
S7-200 module.
For extreme cases: SIPLUS additions
Use under extreme conditions – no prob-
lem! SIPLUS additions are the solution for
use in extended temperature ranges, for
protection against condensation, or for other
voltage ranges. Its CPUs are matched to
the special demands.
