Data Transfer with the DP Master
User Data Transfer Via an Intermediate Memory
The user data is located in an intermediate memory in the IM 151/CPU. This
intermediate memory is always used when user data is transferred between the
IM 151/CPU and the DP master. The intermediate memory consists of a maximum
of 32 address areas.
