These blocks initialize and control communication between ibaPDA and the S7 controller.
The ibaREQ iba block family allows access exclusively to non-optimized data blocks. Addressing is done by using the operand address.
One set of Request blocks has to be called for each Request module (connection) in ibaPDA. The blocks used are part of the iba S7 library, see iba S7 library.
Note |
|
|---|---|
 |
Only use Request blocks from the latest iba S7 library! Request blocks in application examples can be outdated and, thus, cause errors. |
Use different Request block combinations depending on the current system configuration:
|
Request block |
S7-300 with integrated DP interface |
S7-400(H) with integrated DP interface and CP443-5 |
S7-300 with integrated PN interface |
S7-400 with integrated PN interface and CP443-1 (PROFINET) |

ibaREQ_M (Management) The block realizes the communication with ibaPDA. Ideally, the block is called in OB1.
-
ibaREQ_PN/ibaREQ_DP (provision and sending of current signal values) The block provides the current signal values using the transmission cycle. Ideally, the block is called in a cyclic interrupt OB.
-
ibaREQ-PNdev (diagnostics for PROFINET device)The block performs cyclic diagnostics for availability of the PROFINET device used.
-
ibaREQ_DB (interface DB) This DB acts as an interface to ibaPDA and between the different Request blocks.
