Abstract: A modular control system, which is constructed from terminal modules and function modules to fit these, for use in industrial automation in particular is provided. With the known embodiments, which comprise different terminal modules for different functionalities, subsequent system extensions can often only be achieved with significant outlay. With the inventive modular control system this problem is resolved by the use of novel terminal modules of identical structure, with the different functionalities being provided by additional function units. Additional advantages, in addition to simpler modification of the system configuration, are lower planning and assembly outlays, simpler and error-free pre-assembly of the standard terminal modules, simpler stocking of spare parts, clear transparency in respect of the supply of supply voltages, potential forwarding and separation and specialist functions such as simple and transparent handling during gradual commissioning.
