Switch
PROFIBUS is a linear network. The communication nodes are linked by means of a passive
cable - the bus.
By contrast, Industrial Ethernet consists of point-to-point connections: each communication
node is interconnected directly with precisely one other communication node.
If a communication node is linked to several communication nodes, this communication node
is connected to the port of an active network component - the switch. Other communications
devices (including switches) can then be connected to the other ports of the switch. The
connection between a communication node and the switch remains a point-to-point
connection.
The task of a switch is thus to regenerate and distribute received signals. The switch "learns"
the Ethernet address(es) of a connected PROFINET device or additional switches and only
forwards those signals that are intended for the connected PROFINET device or switch.
A switch has a specific number of connections (ports). You connect at most one PROFINET
device or additional switch to each port.
Technology object
A technology object supports you in the configuration and commissioning of a technological
function.
The properties of real objects are represented by the technology objects in the controller.
Real objects can be, for example, controlled systems or drives.
The technology object includes all data of the real object that is required for its open-loop or
closed-loop control, and it signals the status information.
TIA Portal
Totally Integrated Automation Portal
The TIA Portal is the key to the full performance capability of Totally Integrated Automation.
The software optimizes all operating, machine and process sequences.
Total current
Sum of the currents of all output channels of a digital output module.
TWIN end sleeve
End sleeve for two cables
Type of coordination 1
The motor starter may be non-operational after a short circuit has been cleared. Damage to
the motor starter is permissible.
