The following system requirements apply for use of the ibaPDA-Request-S7-DP/PN/ibaNet-E data interface:

  • ibaPDA v8.13.0 or higher

  • Base license for ibaPDA + license for ibaPDA-Request-S7-DP/PN/ibaNet-E

  • ibaBM-PN, ibaBM-DP, ibaBM-DPM-S, ibaCom-L2B or ibaPDA-interface-ibaNet-E

  • ibaFOB-D card in the ibaPDA computer when using ibaBM-PN, ibaBM-DP, or ibaBM-DPM-S for coupling using fiber optics

  • SIMATIC S7 controller S7-300, S7-400, S7-400H, S7-1500, WinAC (not all Request S7 variants are available for all controller types), for access to optimized data blocks S7-1500 firmware V3 or later

  • If using PC/CP connections:

    • SIMATIC STEP 7/SIMATIC NET, or

    • SIMATIC TIA Portal

  • SIMATIC CFC (from V6.0, not for TIA Portal), if signals are to be selected using drag & drop

For integration of Request blocks into S7 program:

  • SIMATIC STEP 7 V5.4 SP5 or higher, or

  • SIMATIC STEP 7 (TIA Portal) V18 or higher for access to optimized data blocks (function block libraries for older versions may be available on request)

For further requirements for the used computer hardware and the supported operating systems, refer to the ibaPDA documentation.
System constraints

  • Access to S7-1200 controllers is not supported.

  • Connectors for STEP 7 CFC blocks that have constant values assigned have no operand address. They are marked as constant in the address book and cannot be selected as signals.

  • If function blocks (FBs) are used in STEP 7 CFC, the internal static variables for the FB also appear in the address book because they are handled in exactly the same way as connectors by the compiler. These are to be ignored.

  • ibaPDA supports the following data types for acquisition:

    • BOOL, BYTE, WORD, DWORD, INT, DINT, REAL, TIME, CHAR

      All other data types appear in the address book but cannot be entered in the signal list.

  • For functions (FCs) with connections of STRING, POINTER, STRUCT or ANY data types under STEP7 CFC, the interpretation of the SCL code does not work, as the source does not contain any references to the data types.
ibaREQsym block family

  • Firmware V3.0 or higher

  • Supported items: E, A, M and items from data blocks, only elementary data types and individual items from structured data types

  • Variables must have the attribute "Accessible from HMI/OPC UA/Web API" or "Writable from HMI/OPC UA/Web API".

  • Max. length of symbolic variable name (fully qualified name including namespace): 254 UTF-16 characters

  • Max. 10 Request instances can be simultaneously active per S7 CPU.

  • Max. 2000 symbols can be simultaneously requested per S7 CPU.

Further information about the "ResolveSymbols" and "MoveResolvedSymbolsToBuffer" functions can be found in the Siemens documentation.
ibaREQ3sym block family

  • TIA Portal V19 or higher

  • Firmware V3.0 or higher

  • Supported items: E, A, M and items from data blocks, only elementary data types and individual items from structured data types

  • Variables must have the attribute "Accessible from HMI/OPC UA/Web API" or "Writable from HMI/OPC UA/Web API".

  • Max. length of symbolic variable name (fully qualified name including namespace): 254 UTF-16 characters

  • Max. 10 Request instances can be simultaneously active per S7 CPU.

  • Max. 2000 symbols can be simultaneously requested per S7 CPU.
