HTTP
Hypertext Transfer Protocol (HTTP). Protocol for data transmission across a network.
HTTPS
Hypertext Transfer Protocol Secure (HTTPS). Protocol for tap-proof transmission of sensitive
data across a network.
Identification data
Identification data is stored on a module, and contains information which supports the user in
● Checking the system configuration
● Locating hardware changes in a system
● Correcting errors in a system
Modules can be clearly identified online using the identification data.
Master
The master in possession of the token is an active device. This master has the option to
receive data from other devices and to send data to other devices.
PROFIBUS
PROcess FIeld BUS, process and field bus standard specified in standard IEC 61784-1:2002
Ed1 CP 3/1. It specifies functional, electrical, and mechanical properties for a bit-serial field
bus system.
PROFIBUS is available with the protocols DP (= Distributed I/O), FMS (= Fieldbus Message
Specification), PA (= Process Automation), or TF (= Technological Functions).
PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents the
consistent continuation of:
● PROFIBUS DP, the established field bus
● Industrial Ethernet, the communications bus for the cell level
Experience gained from both systems was and is being integrated into PROFINET.
PROFINET as an Ethernet-based automation standard from PROFIBUS International
(previously PROFIBUS User Organization) defines a vendor-independent communication,
automation, and engineering model.
