Glossary
CPU
Central Processing Unit - here processor of the PC
CPU load
Load on the CPU of the PC - here: resulting from DP communication
Data_Ex
The slave is ready for productive operation
Data transmission rate
Transmission rate on the bus (unit: bps). A bus parameter for PROFIBUS. The
data transmission rate used depends on various conditions such as distance.
DB
Here: Database - The local database describes the communications network from
the view of the local system.
Deadlock
When more than one parallel process (here: threads) become blocked (A waits for
B and B waits for A).
Distributed I/Os
An input/output module used in a distributed configuration. The connection
between the programmable controller and the distributed I/Os is established via
the PROFIBUS bus system. For the programmable controller, the distributed I/Os
are no different from local process inputs/outputs.
DP
Distributed peripheral I/Os, communication protocol for PROFIBUS complying with
EN 50 170 Volume 2.
