Power module
The power module (PM) opens a new potential group for the load voltage supply 2L+.
Process image (I/O)
The CPU transfers the values from the input and output modules to this memory area. At the
start of the cyclic program, the CPU transfers the signal states of the input modules to the
process image input. At the end of the cyclic program, the CPU transfers the process image
output as a signal state to the output modules.
Product version (PV) = Function version (FV)
The product version or function version provides information on the hardware version of the
module.
PROFINET
PROcess FIeld NETwork, open Industrial Ethernet standard that continues PROFIBUS and
Industrial Ethernet. A vendor-neutral communication, automation and engineering model,
defined as an automation standard by PROFIBUS International e.V.
PROFINET component
A PROFINET component includes the entire data of the hardware configuration, the
parameters of the modules and the corresponding user program. The PROFINET
component is composed of:
● Technological function
The (optional) technological (software) function includes the interface to other PROFINET
components in the form of interconnectable inputs and outputs.
● Device
The device is the representation of the physical automation device or field device
including the I/O, sensors and actuators, mechanics and device firmware.
PROFINET IO device
Distributed field device that can be assigned to one or more IO controllers (e.g. distributed
I/O system, valve terminals, frequency converters, switches).
PROFINET IO
Communication concept for the realization of modular, distributed applications in the
framework of PROFINET.
