Page 2: Warranty And Liability
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.

Page 10: Optimized Blocks
2.6 Optimized blocks Optimized blocks S7-1200/1500 controllers have optimized data storage. In optimized blocks, all tags are automatically sorted by their data type. The sorting ensures that data gaps between the tags are minimized and that the tags are stored access-optimized for the processor.

Page 11: S7-1500: Setup Of Optimized Blocks
S7-1500 can directly read or write all tags with just one machine command). Boolean tags are stored as byte for faster access. The controller therefore does not have to mask the access. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…

In the case of type-identical allocations between two tags with different storage locations, the system converts automatically. In the case of structured tags, this conversion requires performance and should therefore be avoided, if possible. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…

Page 23: System Constants
For S7-300/400 controllers the identification of hardware and software components is performed by logic address or diagnostic addresses. For S7-1200/1500 the identification is by system constants. All hardware and software components (e.g. interfaces, modules, OBs, …) of the S7-1200/1500 controllers have their own system constants. The system constants are automatically created during the setup of the device configuration for the central and distributed I/O.

Page 25: Stop Mode In The Event Of Errors
TIA Portal. This approach makes the S7-1200/1500 controllers more fault tolerant to errors than their predecessors. Advantages There are only three fault situations that put the S7-1200/1500 controllers into the STOP mode. This makes the programming of the error management clearer and easier.

For S7-1200/1500 controllers there are other programmable error OBs (diagnostic error, module rack failure, etc.). More information on error responses of S7-1200/1500 can be found in the online help of the TIA Portal under “Events and OBs”. Programming Guideline for S7-1200/1500… -
Page 27: General Programming
Due to a good and structured program you get many function units that can be multiply reused within a project and also in other projects. These function units then usually only differ by a different configuration (see chapter 3.2.8 Reusability of blocks). Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…
-
Page 28: Organization Blocks (Ob)
OBs are the interface between the operating system and the user program. They are called by the operating system and control, e.g. the following processes: Startup behavior of the controller Cyclic program processing Interrupt-controlled program processing Error handling Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…
-
Page 29
OBs, use the global DBs (see chapter 4.2 No bit memory but global data blocks). Divide all program parts that belong to each other into folders and store them for reusability in the project or global library. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674… -
Page 30: Functions (Fc)
FCs are blocks without cyclic data storages. This is why the values of block parameters cannot be saved until the next call and has to be provided with actual parameters when called. Properties FCs are blocks without cyclic data storages. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…

Temporary and out tags are undefined when called in non-optimized blocks. In optimized blocks, the values are always preset to the default value (S7-1500 and S7-1200 Firmware V4). Thus, the resulting behavior is not accidental but reproducible. In order to permanently save the data of an FC, the functions of the global data blocks are available. -
Page 32: Function Blocks (Fb)
Temporary and out tags are undefined when called in non-optimized blocks. In optimized blocks, the values are always preset to the default value (S7-1500 and S7-1200 Firmware V4). Thus, the resulting behavior is not accidental but reproducible. Static tags keep the value from cycle to cycle…
-
Page 33: Instances
The following figure shows an FB that uses another FB (“IEC Timer”). All data is saved in a multi instance DB. It is thus possible to create a block with an independent time behavior, for example, a clock generator. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…
-
Page 34
If you require the time and counter function, use the “IEC Timer” blocks and the “IEC Counter” blocks instead of the absolutely addressed SIMATIC Timer. If possible, also always use multi-instances here. This keeps the number of blocks in the user program low. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674… -

Page 36: Downloading Without Reinitialization
3.2.7 Downloading without reinitialization In order to change user programs that already run in a controller, S7-1200 (firmware V4.0) and S7-1500 controllers offer the option to expand the interfaces of optimized function or data blocks during operation. You can load the changed blocks without setting the controller to STOP and without influencing the actual values of already loaded tags.

Define a memory reserve for blocks that are to be expanded during commissioning (e.g. test blocks). The commissioning process is not interrupted by download of new defined tags. The current values of already existing variables are kept. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674… -
Page 38
You can also set a default value for the size of the memory reserve for new blocks in the TIA portal. In the menu bar, navigate to «Options – Settings» and then to «PLC programming – General – Download without reinitialization“. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674… -

Page 40: Block Interface Types
Call-by-value with In interface type When calling the block, the value of the actual parameter is copied onto the input parameter of the block for the In interface type. For this, additional memory is required. Programming Guideline for S7-1200/1500 V1.2, Entry ID: 81318674…

Page 47: Symbolic Addressing
If the retentive memory on the PLC is not sufficient, it is possible to store data in the form of data blocks that are only located in the load memory of the PLC. The following entry is described by taking the example of an S7-1200. This programming also works for S7-1500.

Basic instructions Extended instructions Technology Communication S7 communication Definition: SIMATIC-homogeneous data exchange between SIMATIC CPUs via PROFIBUS PROFINET/Industrial Ethernet. With S7 communication, you connect existing S7-300/400 to S7-1200/1500 or migrate existing systems to S7-1200/1500. Recommendation: Use open communication for data exchange between S7-1200/1500 and thus the possibilities of common Ethernet standards. -
