Introduction
This simple program example shows how you use the transfer areas of an I-device.
Requirements
You have configured an I-device.
Task
The result of an "AND logic operation" of two inputs (preprocessing) in the I-device is to be
provided to the higher-level IO controller. This result is to be assigned to a local output in the
IO master (further processing).
Use a transfer area with the following addresses for this purpose:
● Address in the I-device: Q568
● Address in the IO controller: I68
Required steps
The following steps to solve the task:
1. Configuring the transfer area
2. Programming I-device
3. Programming IO controller
