Powerlink communication I/O module object for Bernecker & Rainer
 analog input unit with 4 channels.

 The module object is configured below a Powerlink Controlled Node object
 in the Node hierarchy. This module object also contains input 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.

 The Epl_CN object also needs an Epl_MN and an EplHandler object, see these
 objects for more information.

Example of a B&R analog input unit

 One example of a analog input unit working with object BR_Ai4_EplModule
 is the X20AI4632 (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.
