Installation of a CPU 41x-H

Interface for Expanded Memory

CPU 417-4H provides an additional interface for expanded memory. This make it
possible to expand the working memory. (See Chapter 4.5 )

Slot for Interface Modules

The H synchronization module can be inserted into this slot.

MPI/DP Interface

You can connect the following devices to the MPI of the CPU, for example:
• Programming devices
• Operation and monitoring devices
• Additional S7-400 or S7-300 controllers (see Section 4.6).
Use the bus connector with an angular outgoing cable (see the Installation manual,
Chapter 7)
You can also configure the MPI interface as a DP master and use it as a
PROFIBUS DP interface with up to 32 DP slaves.

Profibus-DP Interface

You can connect the distributed I/O, programming devices/OPs and additional
DP master stations to the PROFIBUS DP interface.
