Special field bus features when setting up the field bus
modules
9.1 CAN
DeviceNet
Field bus subscribers in the CAN DeviceNet are normally integrated using an EDS file (Electronic Data
Sheet). This configuration file permits access to the module configuration.
The BUSINTX11 DeviceNet is supplied together with the file BUSINTX11.EDS.
The module configuration is carried out as follows:
9.1.1
Connections
The module can be configured using what are known as connections. The number of useable
connections depends on the profile being used. Each usable connection has a defined quantity of input
data and output data. The data position of the profile always starts with the first byte of a relevant
connection.
Each connection can in theory be assigned to another connection type (Polled, COS, Strobed). However,
each connection type can only be assigned once (separated for input data and output data). The number
of data items available per connection can be read out using the “InputX length” and “OutputX length”
parameters via the configuration tool.
Here, “InputX length” stands for process status data and “OutputX length” for actuation data.
9.1.2
Example for I/O data
In the example above, the profile selected is offered for connection 1, 10 bytes of actuation data and 12
bytes of process data.
