S7-1200 and TIA portal software
The S7-1200 is the successor of the S7-200. The S7-1200 is designed for and sold in the world-
wide marketplace.
The SIMATIC S7-200 products are declared phased-out products effective 10/01/2013. With
their phase-out declaration, the products will still be available as new components for another year
until 10/01/2014. After that, the products can be obtained as spare parts for an additional 9 years.
For new applications, it is recommended to employ SIMATIC S7-1200 products with the
configuration software STEP 7 Basic.
The TIA portal with STEP 7 Basic programming (ordered separately from the hardware) is used
for programming the S7-1200.
- Provides LAD (Ladder diagram, FBD (Function Block Diagram), and SCL (Structured Control
Language) programming editors.
- STL (Statement List) programming is not supported.
- Includes WinCC Basic for configuring HMI Basic panels.
- No separate USB license stick is required. The software is automatically activated when
installed.
To move project files from one PC to another PC, use the Windows explorer and file
compression to copy the project directory structure.
S7-1200 Agency approvals
S7-1200 hardware has the necessary approvals for the US and European market.
The S7-1200 has cFMus approval for hazardous locations:

Password protection
S7-200: Off-line block protection passwords provide know-how protection that prevents
unauthorized access to your code blocks.
The S7-200 on-line password level is assigned in the system block . There are no restrictions
on any on-line password level to read/write user data, stop/start/restart the CPU, and
read/write the time-of-day clock.
-Level 1 full access: No protection
-Level 2 restricted access: A password is required to download to a CPU, view STL status,
delete user program/data/configuration, force program data, copy to the memory cartridge,
and write to the outputs in STOP mode.
-Level 3 restricted access: In addition to the level 2 restrictions, a password is also required to
upload the user program, data, and the CPU configuration.
S7-1200: Off-line block protection passwords provide know-how protection that prevents
unauthorized access to your code blocks.
The S7-1200 on-line password level is assigned in the CPU device configuration properties.
-Level 1 full access: No protection
-Level 2 read access: The CPU allows HMI access and all forms of PLC-to-PLC
communications without password protection. Password is required for modifying (writing to)
the CPU and for changing the CPU mode (RUN/STOP).
-Level 3 HMI access: The CPU allows HMI access and all forms of PLC-to-PLC
communications without password protection. Password is required for reading the data in
the CPU, for modifying (writing to) the CPU, and for changing the CPU mode (RUN/STOP).
-Level 4 No access: The CPU allows no access without password protection. A password is
required for HMI access, reading the data in the CPU, for modifying (writing to) the CPU, and
for changing the CPU mode (RUN/STOP).
I/O address assignment
S7-200 : I/O addresses are automatically fixed by the CPU operating system according to
module location.
S7-1200: The default I/O assignment can be modified by Device configuration properties.

S7-1200 serial communication
MODBUS RTU is possible on both RS485/422 and RS232 signal modules.
The USS library is supported on the RS485 port and is included with STEP 7 Basic.
The CM 1241 RS232 module supports handshaking.
The S7-1200 RS232 and RS485/422 modules have electrically isolated ports.

S7-1200 Ethernet communication
The PROFINET port on the CPU supports simultaneous communication connections:
OPC server (Object Linking and Embedding OLE) for Process Control server. OPC
functionality is possible using the SIMATIC NET OPC Server.
PROFINET functionality including controller and device
The S7-1200 Ethernet interfaces are designated as PROFINET which supports PROFINET IO
and iDevices.
Communication with 3rd party devices via the Ethernet is supported. The S7-1200 has "Native"
Ethernet TCP/IP protocol available ("FreePort" for Ethernet) for custom development of this
functionality. It is possible to communicate with 3rd party PLCs as long as they support the same
open Ethernet connectivity as the S7-1200.

S7-1200 HMI general
HMI Basic Panels can communicate with up to four S7-1200 CPUs.
Compatibility with current HMI Ethernet devices
MP277 and 377 (discontinued panels) can communicate with the S7-1200. Use WinCC flexible
for programming and select the S7-300 communication channel (Rack 0 - Slot 0) at the start.
HMI update rate
S7-200: HMI data update occurs at end of the program scan and is therefore scan rate limited.
S7-1200: HMI data update occurs asynchronously during the program scan. You must ensure
that data variables are buffered from change, during program processing where new HMI data
values are generated.

Siemens provides products and solutions with industrial security functions that support the secure
operation of plants, solutions, machines, equipment and/or networks. They are important
components in a holistic industrial security concept. With this in mind, Siemens’ products and
solutions undergo continuous development. Siemens recommends strongly that you regularly
check for product updates.
For the secure operation of Siemens products and solutions, it is necessary to take suitable
preventive action (e.g. cell protection concept) and integrate each component into a holistic, state-
of-the-art industrial security concept. Third-party products that may be in use should also be
considered. You can find more information about industrial security on the Internet
(http://www.siemens.com/industrialsecurity).
To stay informed about product updates as they occur, sign up for a product-specific newsletter.
You can find more information on the Internet (http://support.automation.siemens.com).

1st gen: TP1500 BASIC COLOR PN 15“-256 colors, touch
HMI Basic panels require a PC for a download operation. They do not have memory cards.
WinCC Flexible Micro will be available as long as HMI Micro panels (for the S7-200) are sold.
At this time there are no plans for discontinuing the micro panel.
Library graphics are created in WinCC Flexible.
It is not possible to migrate any library items directly from WinCC Flexible to WinCC Basic.
However, you can copy all the elements from the library to an HMI screen in a project and
then migrate the resulting project into WinCC Basic.
Changing from WinCC flexible to WinCC Basic: A firmware update is not necessary in the
case of WinCC flexible 2008 and WinCC Basic.
The S7-1200 does not support Sm@RtAccess or Sm@rtService.
The TIA Portal provides the tools for managing and configuring the devices in your project,
such as PLCs and HMI devices. As a component of the TIA Portal, STEP 7 Basic provides
three programming languages (LAD, FBD, and SCL). The TIA Portal also provides the tools
for creating and configuring the HMI devices in your project.

S7-1200 SIMATIC memory card usage
Before programming a memory card, be sure there is a valid network configuration in your project
so that it can connect to the PLC after installing the card.
SIMATIC memory cards are pre-formatted with a SIMATIC memory format that must be preserved.
Do not use a PC to delete the two hidden files __log__ (system file) and crdinfo.bin (bin file). Do not
use a PC to reformat the memory card or the card will become unusable.
Refer to the S7-1200 Programmable controller system manual for details on how to create and use
a “Program” card and “Transfer” card.
