Connection plug
The connection plug provides the physical connection between devices and the cable, for
example.
Consistent data
Data whose content belongs together and must not be separated is known as consistent
data.
Counter
Counters are components of the system memory of the CPU. You can modify the content of
the "counter cells" using STEP 7 instructions (e.g. count up/down).
CPU
The CPU uses the integrated system power supply to supply the electronics of the modules
via the backplane bus. The CPU contains the operating system and executes the user
program. The user program is located on the SIMATIC Memory Card and is processed in the
work memory of the CPU. The PROFINET interfaces on the CPU allow simultaneous
communication with PROFINET devices, PROFINET controllers, HMI devices, programming
devices, other controllers and other systems. The S7-1500 CPUs support operation as an IO
controller and I-device. Similarly to the PROFINET interface, the PROFIBUS interface available
on some of the S7-1500 CPUs allows communication with other devices. When the interface
is used as PROFIBUS DP interface, the CPU on the PROFIBUS DP also assumes the role of a DP
master.
Crimping
Procedure whereby two components joined together, e.g. wire end sleeve and cable, are
connected with one another through plastic strain.
Cycle control point
The cycle control point marks the end of a cycle and the start of the next cycle. The cycle time
statistics and monitoring of the configured maximum cycle time start at the cycle control
point.
Once the cycle control point has been reached, the CPU writes the process image output to
the output modules, reads the state of the inputs to the input modules and then executes the
first cyclic OB.
Cycle time
The cycle time represents the time a CPU requires to execute the user program once.
Cyclic interrupt
You can find relevant information under the entry "Interrupt, Cyclic "
