Configuration in STEP 7

In the following, we describe the configuration of the Request blocks in STEP 7 V5.

Copy the required blocks from the iba S7 library to the blocks folder of your STEP 7 project, see iba S7 library.

The request blocks do not support multi-instance calls.

If the block numbers in your project are already occupied, assign new numbers to the blocks from the iba S7 library when copying.

Adapt the blocks ibaREQ_UDPint, ibaREQ_UDPext3 and ibaREQ_UDPext4 in the following cases:

For the block ibaREQ_UDPact, another function block number than FB145 is used.
For the ibaUDT_UDPact data type, another number than UDT145 is used.
For the Siemens function blocks of the standard library or the SIMATIC NET CP library, other numbers than the standard numbers are used. The relevant Siemens function blocks are:
- when using ibaREQ_UDPint (FB146): TCON (FB65), TDISCON (FB66), TUSEND (FB67), TCON_PAR (UDT65), TADDR_PAR (UDT66)
- when using ibaREQ_UDPext3 (FB147): AG_SEND (FC5)
- when using ibaREQ_UDPext4 (FB148): AG_LSEND (FC50)
