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