Hazardous Area (You can find more article numbers for the R/H redundant system on the Programmable logic controller for the open-loop and closed-loop control of process chains in
the process engineering industry and in manufacturing technology. The automation system
consists of different components and integrated system functions according to the
automation task.
Backup CPU
Role of a CPU in the R/H redundant system. If the R/H system is in the RUNRedundant
system state, the primary CPU controls the process. The backup CPU processes
the user program synchronously and can take over process control if the primary CPU fails.
Baud rate
Data transmission rate indicates the number of bits transmitted per second (baud rate = bit
rate).
Bit memory
Bit memory is a component of the system memory of the CPU for saving intermediate
results. You access the bit memory through the user program bit by bit, byte by byte, word
by word or double word by double word.
Bus
Joint transmission path to which all devices in a fieldbus system are connected.
Bus cable connector
The bus cable connector is the physical connection between bus node and bus cable.
Bus, self-assembling
The modules are lined up on the mounting rail. They are mechanically and electrically
connected to each other with a U connector as they are swiveled into position. In this way
the bus is extended with each module.In SIMATIC S7, a code block contains part of the STEP 7 user program.
Configuration
Systematic arrangement of the individual modules (configuration).
Connection plug
The connection plug provides the physical connection between devices and the cable, for
example.
Consistent data
Consistent data is data that belongs together in terms of content. Consistent data items are
read and written together.
