CPU 221 installed are:

Integrated 24 V encoders/load power supply:
To directly connect the sensor and encoder. With 180 mA, it also can be used as the load power supply.
Two type:
Take a variety of power and control voltage
The built-in digital input/output:
Six input and four output.
A communication interface:
optional
As PPI interface, used for program function and HMI function (TD 200, OP), S7-200 internal CPU/CPU communication (9.6/19.2/187.5 KBPS), or from the stand as the MPI, used for MPI and standing (S7-300 /-400, OP, TD, button board) exchange data.
The user programmable interface (FreePort), take interrupting capacity, and the equipment used for Siemens serial data exchange, for example in the ASCII agreement, baud rate of 1.2/2.4/4.8/9.6/19.2/38.4/57.6/115.2 Kbit/s, but will PC/PPI cable to use as RS 232 / RS 485 adapter.
Interrupt input:
The rise of process signal along or down to very high speed along the response
High-speed counter:
Four high-speed counter (30 kHz), but through the parameter Settings make can and reset input, with two separate input, and used as increase/down to counter; Or can be connected with 90 ° 2 is incremental encoder.
The simulation device (optional) :
For integration of the input of simulation and the user program test.
Simulation potentiometer:
A simulation potentiometer, can be in daily work used as a set value counter, for example set time.
Pulse output:
2 a high-frequency pulse output (maximum 20 kHz);
Can be used for positioning task, drive and frequency conversion motor stepping motor.
Real time clock (can be used as optional modules connected) :
For example used to give a message plus time mark, record the machine running time or used for the process control based on time.
EEPROM son module (option) :
Used to maintain integrity of STEP 7-Micro/WIN the user program and other documents.
Used to support data record function and formula management.
Allows fast modify the program (even if no programming device) and other program file.
Through the battery to provide a long time backup:
But will storage time increased to 200 days. Without the battery module, user data (such as the memory a state, data block, timer and counter) through the internal super capacitor protection, about 5 days. Can permanently kept the user program (free maintenance). Insert the battery module son memory slots in the module.
