PROFIBUS
Bus system based on the PROFIBUS standard. Components of the SIMATIC S5 and S7 series (programming devices, programmable logic controllers, programmable control systems, distributed I/Os) can be networked using
PROFIBUS.
Programmable Logic Controller System
The programmable logic controllers (PLC) of the SIMATIC S5 system consist of one or more CPUs and various I/O modules. The PLCs of the SIMATIC S7 system (for example,
Programmable Controller (AS)
This programmable controller (PLC) consists of the central unit, a CPU and of diverse I/O modules.
