IP 265
13 Sample Applications and Programming Aids
13.1 Sample Programs
The following sections deal with the programming of the IP 265 and the CPU for control of high-
speed subprocesses within a process by presenting practice-related examples.
There are three sample applications, each more complex than its predecessor as regards the user
programs and the use of the IP 265 interfaces. You will find one example each for IP 265 control:
a) without parameter interchange between IP 265 and CPU ( Section 13.1.1)
b) with parameter interchange between IP 265 and CPU ( Section 13.1.2) and
c) with expansion and parameter interchange between IP 265 and CPU ( Section 13.1.3).
Different IP 265 interfaces are used in the three examples, depending on the application:
a) uses the 24 V inputs and 24 V outputs
b) uses the 24 V inputs, 24 V outputs and output parameters
c) uses the 24 V inputs, 24 V outputs, input parameters, output parameters and expansion

In the various sections, you will find for each sample program information:
• on the problem definition for the sample application
• on subdividing the process between IP 265 and CPU
• on program conversions in the IP 265 user program and
• on program conversions in the CPU user program.
