KNX/EIB2S7 Editor and Function Blocks for Commuication to KNX/EIB BUS over ETHERNET : version 1.0

  • Entry
  • Associated product(s)

KNX/EIB2S7 is a program system consisting of the KNX/EIB2S7 editor and S7 driver blocks for communication with KNX/EIB nodes.

The availability of KNX/IP interfaces enables you to convert message frames from the KNX/EIB bus to Ethernet. The S7 driver blocks of KNX/EIB2S7 allow you to monitor KNX/EIB message frames, as well as to send commands to nodes via Ethernet.

Permanent monitoring of the message frames stores data that sporadically arrives from the KNX/EIB bus in data blocks of the SIMATIC S7 PLC. The data do not to be called up, they can be processed event-driven. The "updated flags" are set by the KNX/EIB2S7 driver in order to detect the update status of a value.

In addition to monitoring values, you can also explicitly read values, for example, a query for the current room temperature. A read request generates a normal message from with the current values at the sensor. These values are then written in the DBs via the monitoring mode. You can explicitly wait for values by querying the "updated flag".

Write jobs are sent via S7 driver blocks to actuators connected to the KNX/EIB bus.

The KNX/EIB2S7 editor enables you to conveniently configure the S7 driver blocks to provide for extremely simple calls without any further configuration in SIMATIC S7.

The software in version 1.0 is released for:

As KNXnet/IP – Interfaces could be used:

IP Controller N 350E

IP Interface N 148/21 und N 148/22

IP Router N 146/01 und N 146/02

IP Viewer N 151

 

For the Interface N148/22 and the IP Router N 146/02 the following AddOn is in addition to version 1.0 needed for writing and reading group addresses.

Appendix (.zip-file) (381 KB): KNX/EIB2S7 update for new IP-Interfaces/-Router

KNX/EIB2 S7 update ( 380 KB )

The link leads to the download of the actualized function blocks for the Interface N148/22 and the IP Router N 146/02.

Please unzip the file to …\Step7\libs. The function blocks will be unpacked to the directory KNXEIB2S7.

To communicate with the new interface or router you have to set Bit 1462.0 in the Instance-DB of FB501 of “TRUE”. After that the driver generates cEMI-Frames with Ctrl1 and Ctrl2-Fields given by Byte 1466 and 1467 (Instance-DB of FB501). For the new router these values are set "0" .
