System manual CECX / System overview
3.1.1 Structure of field bus systems
Field bus systems can be assembled by means of plug-in option modules
or add-on field bus modules. This enables communication with remote de-
vices (filed bus slaves) and control systems. The installation of different op-
tion modules in the CECX modular control system makes coupling or a ga-
teway function possible. For example, this makes cross-linking a CANopen
field bus system with a PROFIBUS-DP field bus system possible.
