HMI diagnostics view (WinCC)
The HMI diagnostics view is an object in WinCC. The HMI diagnostics view can only be used
with Comfort Panels and WinCC Advanced RT.
I/O module
Device of the distributed I/O that is used as interface between the controller and the process.
Industrial Ethernet
Guideline for setting up Ethernet in an industrial environment. The main difference to the
standard Ethernet is the mechanical current carrying capacity and interference immunity of
the individual components.
Memory reset
Procedure to set the memories of the CPU to a defined initial state.
PLC
P
rogrammable
L
ogic
C
ontroller: Component of the CNC by which the machine manufacturer
coordinates the interaction between the NC requirements (part program), the inputs of the
machine operator and the current machine state.
PROFIBUS
Standard for fieldbus communication in automation technology.
PROFINET
Open component-based industrial communication system based on Ethernet for distributed
automation systems. Communication technology promoted by the PROFIBUS Users
Organization.
Subnet
Part of a network whose parameters must be synchronized with the devices (e.g., with
PROFINET). It includes the bus components and all connected stations. Subnets can be
linked by means of gateways, for example, to form a network.
System diagnostics
In the SIMATIC environment, the term "system diagnostics" refers to diagnostics of devices
and modules. System diagnostics is used, for example, to monitor the states of the following
components in the system: Power supply, device, I/O.
