Diagnostic software for -> PROFIBUS with which the traffic on the ->
network can be recorded and analyzed.
Synonym for -> bus segment.
Services provided by a communication protocol.
A -> bus parameter for -> PROFIBUS. The setup time specifies the
minimum interval on the sender between receiving an acknowledgment
and sending a new call frame.
Siemens Network and Communication. Product name for -> Siemens
networks and network components.
A bus parameter for -> PROFIBUS. The slot time (TSL) is the time
during which the sender of a -> frame waits for the acknowledgment
from the receiver before detecting a timeout.
A station is identified by an -> PROFIBUS address in the ->
PROFIBUS network.
A subnet is part of a -> network whose -> bus parameters (for example
-> PROFIBUS addresses) must be matched. It includes the bus
components and all attached stations. Subnets can, for example, be
connected together by -> gateways to form a network.
A -> system consists of several subnets with unique -> subnet
numbers. A subnet consists of several ->stations with unique ->
PROFIBUS addresses.
A -> system consists of several -> subnets with unique subnet
numbers.
The SYNC mode is a DP mode in which several or all -> DP slaves
transfer data to their process outputs at a certain time. The time at
which the data is transferred is indicated in the SYNC command (a
control command for synchronization).
All the electrical equipment within a system. A system includes, among
other things, programmable logic controllers, devices for operation and
monitoring, bus systems, field devices, actuators, supply lines.
A -> bus parameter for -> PROFIBUS. The token represents the right
to transmit for a -> station on PROFIBUS. A station compares the
actual token rotation time it has measured with the target rotation time
and depending on the result can then send high or low priority frames.
