Request-S7 for ibaBM-DP can be configured in the following system configurations:

SIMATIC S7 CPU	SIMATIC STEP 7 V5.x (SIMATIC Manager)	SIMATIC STEP 7 V1x Professional (TIA Portal)
S7-300 integrated DP interface	X	X
S7-400 integrated DP interface and CP443-5	X	X
S7-400 integrated DP interface and CP443-5	X	-
S7-1500 integrated DP interface and CM1542-5 or CP1542-5	-	X

For DP Request, the measurement values (Request Handshake) are not requested via the PROFIBUS, but via a separate connection.

Depending on the hardware and software, different access points can be selected for the Request:

• TCP/IP: The connection to the SIMATIC S7 is established using an integrated PN interface of the S7 CPU or the respective CP modules in the PLC and the standard network interface of the computer. No additional Siemens software is required for the connection.

• PC/CP: This is the designation for different SIMATIC specific access points. In contrast to the TCP/IP connection, for the PC/CP group the SIMATIC communication software (and corresponding licenses) must be installed on the computer with the corresponding functions enabled.

  • MPI, PROFIBUS: The connection to the SIMATIC S7 is established using the MPI or PROFIBUS interface of the computer; e.g. with the CP5611 PCI card or the MPI adapter for USB interface or serial PC interface.

  • TCP/IP, ISO: Here, either the standard network interface of the computer or a suitable interface card is used for the connection to the S7.

• TCP/IP S7-1x00: The connection to a SIMATIC S7-1500 is established using an integrated PN interface of the S7 CPU or respective CP modules in the PLC and the standard network interface of the computer. No additional Siemens software is required for the connection.

System integration with ibaBM-DP

The measured data are transmitted to the ibaBM-DP device over PROFIBUS DP.

You need the following connections:

• Online connection between ibaPDA and S7-CPU (TCP/IP, MPI or DP)

• Fiber optic connection between ibaPDA/ibaFOB-io-D and ibaBM-DP

• PROFIBUS connection between ibaBM-DP and S7 PROFIBUS master

• A connection from ibaBM-DP to the network (TCP/IP over Ethernet) is only needed if the device is operated in compatibility mode, i.e. not with 32Mbit Flex (short: Flex). In this case the system integration is like with ibaBM-DPM-S, see Request-S7 for ibaBM-DPM-S .

In the standard version, you can configure a maximum of 8 connections per device, i.e. 8 PROFIBUS slaves. Up to 244 Byte data can be transmitted per slave.

Note
	The following description refers to the Request blocks V4.0 or higher. If you require information regarding older versions, contact the iba Support.
