Integral 24 V encoder/load current supply:
For direct connection of sensors and encoders. With 280 mA, output current can also be used as load
power supply.
CPU 224 XP:
2 device variants with different supply and control voltages.
CPU 224 Xpsi:
1 device variant (24V DC) with current sinking.
Integral digital inputs/outputs:
14 inputs and 10 outputs.
Integral analog inputs/outputs:
2 inputs and 1 output.
2 communication interfaces:
Optional
As PPI interface with PPI protocol for programming functions, HMI functions (TD 200, OP), S7-200
internal CPU/CPU communication (9.6/19.2/187.5 Kbit/s) or as MPI slave for data exchange with MPI
masters (S7-300/-400, OPs, TDs, pushbutton panels).
Freely-programmable interface (freeport) with interrupt facility for serial data exchange with third-party
devices, e.g. with ASCII protocol baud rates 1.2/2.4/4.8/9.6/19.2/38.4/57.6/115.2 Kbit/s; PC/PPI cable
can be used as RS 232/RS 485 converter.
Expansion bus:
Connection of expansion modules (only EMs of the 22x series can be used).
Interrupt inputs:
For extremely fast response to rising or falling edges of process signals.
Fast counters:
6 fast counters (2x200 kHz, 4x400 kHz), with parameterizable enable and reset input, can be used
simultaneously as up and down counters with 2 separate inputs or for connecting incremental encoders
with 2 pulse trains (2x100 kHz, 2x20 kHz) offset by 90o.
Problem-free expansion with digital and analog expansion modules (EM, optional).
Simulator (optional):
For simulating the integral inputs and for testing the user program.
Analog potentiometer:
2 analog potentiometer, can be conveniently used in everyday work as a setpoint encoder, e.g. for setting
times.
Pulse outputs:
2 high-frequency pulse outputs (max. 100 kHz); can be used for positioning tasks and for driving
frequency-controlled motors and stepping motors via power circuitry.
Real-time clock:
e.g. for assignment of time stamps to messages, for recording machine runtimes, or for time control of
processes.
EEPROM submodule (optional):
For saving the complete STEP 7-Micro/WIN user program as well as other documents.
For supporting the data logging function and recipe management.
Permits fast changing of program (even without programming device) and additional program archiving.
Battery module for long-term backup:
To increase the storage period up to typically 200 days. Without a battery module, user data (e.g. bit
memory states, data blocks, times, counts) are saved by an internal high-performance capacitor for
approx. 5 days. The program is always saved permanently (maintenance-free). The battery module is
inserted into the slot for the memory submodule.

Extensive instruction set:
A large number of
Basic operations such as binary logic operations, result allocation, save, count, create times, load,
transfer, compare, shift, rotate, create complement, call subprogram (with local variables)
Integrated communication instructions (e.g., S7-200 communication (Network read NETR, Network
write NETW) or Freeport (Transmit XMT, Receive RCV))
User-friendly functions such as pulse-duration modulation, pulse sequence function, arithmetic
functions, floating-point arithmetic, PID closed-loop control, jump functions, loop functions and code
conversions simplify programming
Counting:
User-friendly counting functions in conjunction with the integrated counters and special commands for
high-speed counters open up new application areas for the user
Interrupt handling:
Edge-triggered interrupts (activated by rising or falling edges of process signals on interrupt inputs)
support a rapid response to process events
Time-controlled interrupts can be set at 1 ms increments from 1 ms to 255 ms
Counter interrupts can be triggered when a setpoint is reached or when the direction of counting
changes
Communication interrupts make exchanging information with peripheral devices such as printers or
bar code readers quick and easy
Direct interrogation and control of inputs/outputs:
Inputs and outputs can also be scanned and set directly independent of the cycle. The controller is then
able to respond quickly to process events (e.g., direct resetting of outputs on the occurrence of an
interrupt).
Password protection:






The 3-level password protection concept effectively safeguards your know-how. The protection concept
has the following options for access to the user program:
Full access: the program can be altered as desired.
Read-only: the program is protected against unauthorized changes. Testing, setting system
parameters and copying the program are possible.
Complete protection: the program is protected against modification and unauthorized readout and
copying. Parameter settings are supported.
Test and diagnostic functions:
User-friendly functions support testing and diagnostics: The entire program is executed and analyzed
using a definable number of cycles. Internal parameters such as bit memories, timers or counters, are
logged in a max. of 124 cycles.
"Forcing” of inputs and outputs during test and diagnostic operation:
Inputs and outputs can be set independently of cycle and thus permanently, for example, to test the user
program.
Runtime edit:
In RUN mode, programs can be edited and modified programs can be loaded into the CPU at the click of
a mouse, without having to interrupt the current program.
Additional mathematical modules such as SIN, COS, TAN, LN, EXP
Data logging:
Time-controlled or event-controlled saving of data records on the EEPROM memory submodule, e.g.
performance data, statistical data, fault/error messages, optionally with a time tag. The log file can be
transferred at any time using the S7 Explorer in STEP 7-Micro/WIN.
Recipe management:
Recipes are defined and downloaded within the STEP 7-Micro/WIN project. For better memory utilization,
the recipes are stored in the EEPROM memory submodule. The recipes can be modified and updated
online.
Programming
The STEP 7-Micro/WIN32 V4 programming package permits complete programming of all S7-200 CPUs.
Note:
The CPU 224 cannot be programmed using STEP 7-Micro/DOS. If programming is to take place via the
serial interface of the PG/PC, the PC/PPI cable is required additionally. If the STEP 7 Micro/Win V4
programming software is used, programming can take place via the SIMATIC CP 5511 or CP 5611 (see
SIMATIC NET) as well as via the MPI interface of the programming device. This increases the maximum
permissible transmission rate to 187.5 kbps.
