Configuring and Programming" manual was stored in the installation folder of STEP Professional or STEP Basic in the "Manuals" subfolder during installation of the STEP Safety optional package SIMATIC Safety V14 readme Readme, 09/2016, A5E32923676-AE Editing devices and networks 3.1 General notes on devices and networks Roaming User Profiles not supported You cannot use STEP Safety in a roaming user profile The software has only limited functionality under these circumstances Contact your domain administrator if you have a roaming user profile Installation of HSPs Make that all HSPs required in the project are installed before you work with the project Configuring phase shifting for the F-OB Assign phase shift parameters for an F-OB using the following formula: Phase shift < Max_Cyc - Cyclic interrupt time Assigning F-destination addresses to fail-safe modules with SIMATIC Safety When using an F-CPU S7-300/400, it is not possible to assign F-destination addresses to the fail-safe modules behind an IE/PB Link SIMATIC Safety V14 readme Readme, 09/2016, A5E32923676-AE Programming PLC 4.1 General Notes on PLC Programming and on Acceptance Content Notes that could not be taken into account in the online help and the manual What you need to observe with regard to the installation of STEP Safety? After the installation of STEP Safety, your safety program will be shown as inconsistent in the Safety Administration Editor Initiate compilation of the safety program You will obtain a consistent safety program as a result The collective F-signature of your safety program remains unchanged Online functions ● It is not possible to open F-blocks via the Lifelist with STEP Safety You have to have the corresponding project opened offline in order to use all of the online functions for F-blocks ● Use the Safety Administration Editor for the offline-online comparison if you wish to view the checksums of F-blocks Upgrading to STEP Safety V14 ● After upgrading a project that contains S7-300/400 F-CPUs, we recommend executing the command "Compile > Software (rebuild all blocks)" ● The name of the F-I/O is a component of the name of the associated F-I/O DB In earlier versions of STEP Safety, it was not always ensured that this component was identical to the name of the F-I/O This is corrected with the upgrade to STEP Safety V14 This does not change the functionality or the collective signature of your safety program However, since the names of the F-I/O DBs have changed, you should generate an upto-date safety summary after the upgrade and add it to your acceptance documents SIMATIC Safety V14 readme Readme, 09/2016, A5E32923676-AE Programming PLC 4.1 General Notes on PLC Programming and on Acceptance Supplement to the "Know-how protection" and "Reuse of F-blocks" sections S7-1200/1500 F-CPUs The following special features apply to STEP Safety V14: ● You cannot create a type in the project library or in a global library from a know-howprotected F-block Solution: Use the master copies or projects as delivery form ● When you call other user-defined blocks in a know-how protected F-block, use the option to sort the know-how protected F-block and the user-defined block it contains as group (folder) in the project tree The following rules apply: – The called blocks must be multi-instances – The called blocks should be know-how-protected If you wish to continue to use the know-how-protected blocks, store the group (folder) as master copy If you wish to continue to use the know-how-protected blocks in another F-CPU, also store the group (folder) as master copy Supplement to the "MOVE: Move value (STEP Safety V14)" section In the basic state, the instruction box contains an output (OUT1) The number of outputs can be expanded The inserted outputs are numbered in ascending order on the box During execution, the content of the operand at the IN input is transferred to all available outputs The instruction box cannot be expanded if operands with F-compliant PLC data types (UDT) are transferred Supplement to the "CTD: Count down (STEP Safety V14)" and CTUD: Count up and down (STEP Safety V14)" sections If you use the CTD or CTUD instruction with version 1.1 in a know-how-protected block, you must open the block by entering the password before compiling in order to change the version of the CTD or CTUD instruction to a version other than V1.1 The same applies if you want to change the version of the CTD or CTUD instruction from a version other than V1.1 to version V1.1 Compiling the safety program The collective F-signature is determined in STEP Safety V14 when you compile the safety program and shown in the Safety Administration Editor under "Code signature" The collective F-signature is valid but the safety program can still be inconsistent This is the case when the hardware configuration is not up-to-date (compiled) Compile the hardware configuration to obtain a consistent safety program The collective F-signature does not change as a result SIMATIC Safety V14 readme Readme, 09/2016, A5E32923676-AE
