+ What should you watch out for with the PPI/MPI/DP interfaces if you want to use the CP 5711 with a SIMATIC S7-200? (2013-12-23) [85669627]
Description The SIMATIC NET CP 5711 is an onboard PB module in the Field PG M4 and when used for an S7-200 you must note the following system properties with regard to the PPI/MPI/PROFIBUS interfaces. PPI: The PPI protocol is not supported by software drivers through the CP 5711. MPI: Limited use of the MPI interface
(Multi Point Interface) is possible and on the PG side works with transmission rates of 187.5 kBaud, 19.2 kBaud and 9.6 kBaud (baud rate preset fo ...

+ How do you archive projects or single PLC folders in STEP 7 (TIA Portal)? (2013-12-23) [62411591]
Instructions The 'Archive' function in STEP 7 versions V5.x, in which you store projects as ZIP files in a storage location, is not supported by STEP 7 (TIA Portal) in V10.5 and V11. In these versions of TIA Portal you save your projects on the hard disk, for example, using the 'Save' and 'Save As' functions. Under 'Tools > Settings > Tab: General' and under 'Memory Settings' you can define the storage location for your projects and libraries.

 + Why are there no GSM antennas with longer cables? (2013-12-13) [85162446]
Description There are currently two antennas in Industrial Remote Communication portfolio: Omnidirectional antenna for GSM-(2G) and UMTS-(3G) networks with a 5m cable (ANT794-4MR) Patch antenna for GSM-(2G) networks with a 1.2m cable (ANT794-3M) ...

 + With the S7-1200, why do you get the message indicating that the signal board is not available because of an incorrect type?  (2013-12-11) [85239632]
Description You get this message because there is a difference between the version of the signal board integrated in the CPU and the version of the signal module configured in the device configuration. There are currently two versions of the S7-1200 analog input board, V1.0 and V2.0. If you configure the signal board version V2.0 in the device configuration, but have slotted the same type but version V1.0 in the CPU, you get this message in the diagnostics buffer: 'Hardware comp ...

+ In STEP 7 (TIA Portal), how can you input, read out and edit the date and time for S7-300/400/1200/1500? (2013-12-09) [43566349]
Description In order to input or read out the date and time of CPU clocks you need the data type 'DT' (DATA_AND_TIME) for S7-300/400 and data type 'DTL' for S7-1200. With the S7-1500 you can choose between three data types: 'DT', 'LDT' and 'DTL'. The 'DT' data type stores the data for date and time in the BCD format, which means in a length of 8 bytes. A variable of the 'DTL' data type has a length of 12 bytes and stores the data for date and time in a predefined structure. More ...

1. Programming guideline for S7-1200/S7-1500
The programming guideline shows you how you can increase your engineering efficiency with the TIA Portal. It contains tips for creating memory- and runtime-optimized user programs and introduces innovations, such as the library concept and slice access. Some of the topics:
  • Optimized blocks
  • Instructions as multi-instance
  • Symbolic programming
  • Global data blocks in place of bit memories

2. Second generation SIMATIC HMI Basic Panels
The panels, with screen diagonals of 4 to 12 inches, feature a high-resolution widescreen display with 64,000 colors. Integrated software functions include: message system, recipe management, trend functionality and language switching. In the case of increased requirements, projects created for a Basic Panel can easily be transferred to devices of other performance classes or display sizes.
The Basic Panels are specially designed for interaction with the SIMATIC S7 controllers and are configured in the Totally Integrated Automation Portal (TIA Portal).

3. Communications processors for modular RTU solutions
Flexible and low-cost RTUs based on SIMATIC S7-1200 can be realized with the new communications processors. All variants of the CP 1243-1 offer cyclic and event-controlled transfer of measured and setpoint values as well as interrupts between the RTU and control center, without complicated programming. 

4. PROFINET driver
The PROFINET driver supports developers who implement PC-based PROFINET applications themselves. It does not require any special hardware because the standard Ethernet interface is used. The PROFINET driver is delivered as source code, which allows developers' own solutions to be ported on different operating systems. An engineering tool is not necessary.
