EDS file (Electronic Data Sheet)
For the DeviceNet bus coupler module EPM-S150, the EDS file "Lenze-EPM-S150_64_10.eds" is
available in the download area of www.Lenze.de. Install this EDS file in your project planning tool.
More information on how to install the EDS file can be found in the manual of your project planning
tool.
8.2.1 Access to the I/O area
The DeviceNet bus coupler automatically detects the I/O compound modules plugged at the
backplane bus and generates the number of the input and output bytes. (Supply and power
distributing modules are not considered.)
When the DeviceNet scanner is configured, the respective total length of the input or output data
must be indicated. Information on I/O assignment of a module can be found in the "Product
description" chapter in the prevailing descriptions of the I/O compound modules.
The position (offset) of the input and output bytes within the input and output data results from
the sequence of the modules (DeviceNet slot 1 ... 64). Use the basic address set for the bus coupler
in the DeviceNet scanner to access the input or output data via the corresponding offset.
During operation, the DeviceNet bus coupler cyclically reads the input data of the peripheral
modules and always provides the current state for the DeviceNet scanner. Output data, the
DeviceNet bus coupler has directly received by the DeviceNet scanner will be directly forwarded to
the modules as soon as they have been received via DeviceNet.
 How to configure the DeviceNet scanner (master):
1. Switch off the voltage supply of the DeviceNet bus coupler.
Set the baud rate and the DeviceNet address.
2. Start your configuration tool for the DeviceNet scanner.
3. Set the "POLL IO" connection type in the DeviceNet scanner.
4. Enter the number of input and output data:
5. Number of input data: Produced connection size
6. Number of output data: Consumed connection size
7. Enter a basic address for the input and output data (mapping).
8. Activate the DeviceNet bus coupler EPM-S150 in the scan list.
9. Start the DeviceNet scanner.
After the DeviceNet scanner has been configured, the input and output modules can be triggered
under the configured addresses.
