Powerlink communication I/O module object for Bernecker & Rainer
digital output unit with 4 channels.
The module object is configured below a Powerlink Controlled Node object
in the Node hierarchy. This module object also contains output channels to
be connected to signals in Plant hierarchy.
Configuration
Place the object under a Powerlink controlled node object of class
Epl_CN (Fig 1) and connect the channels to signals in Plant hierarchy.
The location under the Epl_CN object is dependent on the hardware
configuration. See B&R Case Study in class BR_PowerSupply_EplModule
for more information. Note that the Do module is not mentioned in the Case Study.
The Epl_CN object also needs an Epl_MN and an EplHandler object, See these
objects for more information.

Example of a B&R digital output unit
One example of a digital output unit working with object BR_Do4_EplModule
is the X20DO4322 (Fig 2) together with X20 Bus controller, in this case
Powerlink Bus Controller X20BC0083 (Fig 3).
Description and figures from B&R X20 System Manual.
