Listed briefly in this section is information on the steps required for preparing an
M7-400 for operation:
You will learn the following:
• A checklist with the order in which preparations must be made
• How to connect operator panels and I/O devices
• How to connect a programming device via the COM interface
• How to connect a programming device via the MPI to a single M7-400, to two or
more nodes in a network or to ungrounded nodes
• How to check the status and error display by switching on for the first time
All other information which is important for preparing for operation applies (except
for the reset) both to the S7-400 and M7-400 modules and is described in
Chapter 8.
