S7-1200 and STEP 7 Basic

 The S7-1200 is the successor of the S7-200 and is available in June 2009. It is designed for and will

be sold in the world wide market place.

 The S7-200 will remain an active Siemens product.

 STEP 7 Basic v10.5 programming package (ordered separately) is used with the S7-1200

- Supports LAD and FBD. STL 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.

 An export-import function for an S7-1200 project is not available in the initial release. To move

project files from one PC to another PC, use the Windows explorer and PKZIP to copy the project files

directory structure.

S7-1200 Approvals

 S7-1200 hardware has the necessary approvals for the US and European market.

 The S7-1200 has FM approval for hazardous location:

The Factory Mutual Research (FM): Approval Standard Class Number 3600 and 3611

Approved for use in:

- Class I, Division 2, Gas Group A, B, C, D, Temperature Class 40° C

- Class I, Zone 2, IIC, Temperature Class T4 Ta = 40° C

 The S7-1200 hardware has UL and CE approvals.

The initial release on the STEP 7 Basic V10.5 software and S7-1200 hardware set does not include

the S7-200 expansion module types shown below. To use the S7-1200 CPU for an S7-200 application

that uses these modules, you must use a different method to replace the function of these I/O

modules. For example, there is no S7-1200 RTD or Thermocouple module. However, you can use

standard analog modules with temperature sensors. The user program can perform a linearization of

the sensor output.

Memory

 Expansion modules are automatically recognized when connected and powered

 STEP 7-Micro/WIN “SET PG/PC Interface” window configures the communication driver

 STEP 7-Micro/WIN “Communications” uses the selected driver to scan and connect CPU

stations

 STEP 7-Micro/WIN “System Block” window configures CPU parameters

 A System Block download operation transfers the new hardware configuration into the target CPU

Hardware configuration S7-1200

Hardware

 STEP 7 Basic uses a visual configuration where you create an image of your actual hardware set

 Hardware modules are selected from a hardware catalog tree and dragged into a rack image

 After your system hardware image is assembled, use a mouse click on an item in the system image

to set the configuration “Properties” page for the selected hardware item

 Select the CPU PROFINET connector on the CPU image to set the IP address properties

 Use the Download command to transfer the new hardware configuration to the target CPU. When

prompted, select a network interface and CPU.

Password protection

 S7-1200 Off-line project block password provides Know-How protection to prevent unauthorized

access to one or more of your code blocks (OB, FB, FC, or DB).

 S7-1200 On-line CPU password protection provides 3 levels of security for restricting access to

CPU functions.

I/O address assignment

 S7-200: I/O addresses automatically fixed by CPU operating system according to module location.

 S7-1200: Default I/O assignment can be modified by Device configuration properties.
