Download DEZ 161 Interrupt Processing, Discrete Input

Content Arrangement of this Publication
Chapter 1
General Information
This chapter describes structural elements of interrupt user programs and their effect
on the runtime of the primary user program; it also contains instructions for the creation
of IR user programs. The reader will learn about the cooperation betweenthe DEZ 161
hardware module incl. firmware and the DEZ-related standard function blocks (data
structures).
Chapter 2
Operation
This chapter provides an overview of the indicator and operating elements on the DEZ
161 module.
Chapter 3
Configuration/Design
This chapter lists
all required hardware and software that has to be in place to make the DEZ 161 operational
all special conditions that must be observed when designing the programmable controller
all steps necessary for configuration, parameterization and start-up of the module.
Following the list of configuration steps is a detailed example of an IR application with
actual task definition and hardware configuration as well as a description of the solution. At the end of this example is an FBD representation of the IN and OUT blocks.
In presenting the software solution, an abbreviated method of writing was chosen to
give the reader an opportunity for exact reconstruction of the parameter processing
without the inconvenience of having to look at other pages.
The detailed execution of above mentioned configuration steps is described in the respectiveuser manual of the A250 or U250 programmable controllers, or in the respective software package.
