BACKPLANE WITH PROCESSOR

摘要

The invention relates to a backplane with connections for connecting functional units. Conventional programmable controllers have a backplane with slots into which functional units, e.g. functional units in the form of a CPU, communication, input/output or other module suitable for the programmable controller can be inserted. Should a programmable controller have to be expanded in order e.g. to solve a more complex automation task, it is necessary to equip the programmable controller with new CPU and/or other intelligent functional modules or to replace already installed modules by more powerful ones. This procedure is expensive and prone to error. A backplane (1a; 1b) is proposed which allows adaptation to an automation task that is to be solved.
