S7-200 Micro PLCs
The S7-200 Micro PLC is the smallest member of the SIMATIC
S7 family of programmable controllers
...
Inputs and outputs (I/O) are
the system control points
...
Outputs control other devices, such as
motors and pumps
...
S7-200 Models
There are four S7-200 CPU types: S7-221, S7-222, S7-224,
S7-226, and S7-226XM and three power supply configurations
for each type
...

S7-200 Features
The S7-200 family includes a wide variety of CPUs and features
...
The following table provides
a summary of the major features, many of which will be
covered in this course
...
When the mode switch
is in the STOP position the CPU is stopped
...
The analog adjustment is used to increase or decrease values
stored in special memory
...
Optional Cartridge
The S7-200 supports an optional memory cartridge that
provides a portable EEPROM storage for your program
...
In addition, two other cartridges are available
...
The
battery provides up to 200 days of data retention time in the
event of a power loss
...
Another cartridge is available with a battery only
...
Expansion modules contain
additional inputs and outputs
...
The ribbon connector is protected by a cover on the base unit
...
31
Available Expansion
The S7-221 comes with 6 digital inputs and 4 digital outputs
...
The S7-222 comes with 8 digital
inputs and 6 digital outputs
...
The S7-224 comes with 14 digital inputs
and 10 digital outputs
...
The S7-226 and S7-226XM come with 24 digital inputs
and 16 digital outputs
...
Status Indicators
The CPU status indicators reflect the current mode of CPU
operation
...
When the mode switch
is set to the STOP position, the yellow STOP indicator is lit
...
When the CPU senses an
input is on, the corresponding green indicator is lit
...
A DIN clip
allows installation on a standard DIN rail
...
The S7-200 can also be panel mounted using
installation holes located behind the access covers
...
An S7-200 DC/DC/
DC would be connected to a 24 VDC power supply
...
33
I/O Numbering
S7-200 inputs and outputs are labeled at the wiring terminations
and next to the status indicators
...
This
address is used by the CPU to determine which input is present
and which output needs to be turned on or off
...
The first
number identifies the byte, the second number identifies the
bit
...
0, for example, is byte 0, bit 0
...
0 = Byte 0, Bit 0
I0
...
0 = Byte 1, Bit 0
I1
...
Inputs
34
Input devices, such as switches, pushbuttons, and other sensor
devices are connected to the terminal strip under the bottom
cover of the PLC
...
Input simulators with prewired toggle
switches are available for the S7-200s
...
For
example, the switch on the far left is wired between the first
input (0
...
When the switch is closed, 24 VDC is applied
to the input
...
When the switch
is open, 0 VDC is applied to the input
...
Outputs
Output devices, such as relays, are connected to the terminal
strip under the top cover of the PLC
...
The LED status
indicators signal if an output is active
...
The appropriate connector slides into either the input, output, or
expansion module terminals
...
Instead, the terminal strips are removable
...
36
Super Capacitor
A super capacitor, so named because of its ability to maintain a
charge for a long period of time, protects data stored in RAM in
the event of a power loss
...
Reference Manual
The SIMATIC S7-200 Programmable Controller System
Manual provides complete information on installing and
programming the S7-200 PLCs
...
The five models of S7-200 are ____________ ,
____________ , ____________ , ____________, and
____________
...
Which of the following is not available on an S7-221?
a
...
c
...
Mode Switch
Expansion Port
Programming Port
Status Indicators

...
An S7-222 has ____________ DC inputs and
____________ DC outputs
...
An S7-224 has ____________ DC inputs and
____________ DC outputs
...
The fourth output of an S7-200 would be labeled
____________
...
38
An S7-222 can have a maximum of ____________
expansion modules and an S7-224 can have a maximum
of ____________ expansion modules
...
Connecting External Devices
TD200
The S7-200 programming port can be used to communicate
with a variety of external devices
...
The TD200 displays messages read from the
S7-200, allows adjustment of designated program variables,
provides the ability to force, and permits setting of the time and
date
...
Freeport Mode
The programming port has a mode called freeport mode
...
39
Printer
Freeport mode can also be used to connect to a non-SIMATIC
printer
...
A
total of 31 units can be interconnected without a repeater
