CP50M0 communication module
Buffer memory module
DRAM
Note
Of several CP50M0 or CP51M1 operated in a rack, only the CP50M0/CP51M1 that is
inserted on the extreme left has the buffer memory function. All others can only be
configured as pure communication modules (CP50M0: two PROFIBUS DP/MP interfaces).
