Determinism Determinism
(deterministic) manner.
Device name Before an IO device can be addressed by an IO controller, it must have a
device name. In PROFINET, this method was selected because it is
simpler to work with names than with complex IP addresses.
Refer to page 18
Encoder The PROFINET profile for Encoders is intended to define a standard
Profile application interface for encoders. The profile is a supplement to the
PROFIdrive profile, so it is mandatory to read the PROFIdrive profile
before implementing the encoder profile. Profinet encoders from Datalogic
Automation s.r.l.comply with the Encoder Profile Specifications V4.1
version 3.162. See also "Profile".
Function Functions (FC) are code blocks which can be programmed by the user. A
FC does not have a "memory". Temporary variables as well as
parameters transferred to the function when the latter is called are saved
in a L stack. They are lost following processing of the FC.
Function block Function blocks (FB) are code blocks with a "memory" which are
programmed by the user. They have an assigned instance data block
(instance DB) as memory. Parameters transferred to a FB as well as the
static variables are saved in this data block. An FB contains a program
which is always executed when the FB is called by another code block.
Function blocks facilitate the programming of frequently repeated,
complex functions.
Frame ID The two-byte field in the Ethernet frame which defines the type of
PROFINET IO message.
GSD The properties of a PROFINET device are described in a GSD file
(General Station Description) that contains all the information required for
configuration. In PROFINET IO, the GSD file is in XML format. The
structure of the GSD file conforms to ISO 15734, which is the world-wide
standard for device descriptions. Refer to page 11
GSDML General Station Description Markup Language – The file containing the
XML description of the PROFINET IO device. Refer to page 11
IO Controller Device used to address the connected IO devices. This means that the IO
controller exchanges input and output signals with assigned field devices.
The IO controller is often the controller on which the automation program
runs. Refer to page 39
IO Device A decentralized field device that is assigned to one of the IO controllers
(e.g. remote IO, encoders, valve terminals, frequency converters,
switches, etc.). Refer to page 39
IO Parameter An IO Parameter Server is a server station, usually a PC, for loading and
Server saving the configuration data (records) of IO Devices.
IO Supervisor Programming device, PC or HMI device used for commissioning and
diagnostics of IO Controllers and IO Devices. Refer to page 39.
IP address The IP address is the name of the unit in a network using the Internet
protocol. Refer to page 8.
means that a system responds in a predictable
