The prerequisite for use of Request-S7 using ibaNet-E is a license for ibaPDA-Interface-ibaNet-E (item no. 31.001006).

With the ibaNet-E Request, the measured values (Request Handshake) are requested via a separate TCP/IP 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 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 interfaces.

    • 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.

Up to 1446 bytes of data can be transmitted per configured module.
