11.2.1 Access to 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 distributor
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.
Configure DeviceNet scanner (master)
ƒ Switch off the voltage supply of the DeviceNet bus coupler and set the baud rate
and the DeviceNet address (
¶ 54).
ƒ Start your configuration tool for the DeviceNet scanner.
ƒ Set the "POLL IO" connection type in the DeviceNet scanner.
ƒ Enter the number of input and output data:
Number of input data: Produced connection size
Number of output data: Consumed connection size
ƒ Enter a basic address for the input and output data (mapping).
ƒ Activate the DeviceNet bus coupler EPM−S150 in the scan list.
ƒ Start the DeviceNet scanner.
After the DeviceNet scanner has been configured, the input and output modules can be
triggered under the configured addresses.
