PROFINET

The BIS M-4008 processor unit and the controlling system communicate via PROFINET IO.
The system PROFINET IO consists of the following components:
– IO controller
– IO device (here, the BIS M-4008 processor unit)
In a PROFINET network, IO controllers and IO devices can be connected to each other using all
common network topologies: a radial, linear, ring or tree topology is possible.
Note
The BIS M-4008 has a built-in IRT switch with 2 ports for this purpose. This means
that both RT and IRT can be used.
In order to configure the parameters for the IO controller correctly based on type, the device
master data for the BIS M-4008 compact processor unit are included in the form of a GSD file.
These data can be found on the BALLUFF Web page or on the device Web server.
The data exchange takes place with the host system in the input and output
buffer. The size of these buffers must be configured by the master.
Note
The possible buffer sizes are stored in the GSDML file. A minimum size of 8 and a
maximum size of 254 bytes can be configured; the value must always be an even
number.
The compact processor unit and the host system communicate via the PROFINET protocol.
This means an IP address and a unique device name are required.
The device name and the IP address can be edited using the respective project planning
software used, e.g. “Simatic Manager” and the IO device.
Note
The BIS M-4008 processor unit is shipped without a device name. The GSDML file
has the prepared device name “bism4008”.
