The master interface module adds a DP master interface to the IM 151-7(F-)CPU / IM 151-8(F) PN/DP CPU. A lower-level PROFIBUS DP line can thus be established. This results in the following advantages:
Offloading of the central controller by means of distributed preprocessing
IM 151-7 (F-)CPU / IM 151-8(F) PN/DP CPU is possible as DP master in stand-alone mode
Use of the CPU in hierarchical networks, e.g. with IE/PB Link also on Ethernet (CBA, etc.)
