The buffer size adapts to the data type of the chosen signals. If a Boolean type is mapped, only bit 0 is used in the chosen signal address,
and the remaining 7 bits are not used.
The actual interpretation of the value that is read or written depends on the data type and representation. For example, motor current is
a real-type 32-bit value that is represented as float, and publishing the motor current as an actual value does not need any scaling and
factoring.

Functional Extension Options

2.5
Each functional extension option is defined by its own PROFINET device model with a module and submodule(s).
Slot 1 contains the application and the subsequent slots contain the installed options. Each option supports a module access point
(MAP), and other submodules contain the process data.

Network Topologies

2.6

Overview

2.6.1
Communication interface X1/X2 is used for fieldbus connection.
The communication interface in the iC7 drives and power converters has 2 Ethernet ports (X1 and X2) and an embedded switch with 2
Ethernet RJ45 connectors. It has 1 MAC and IP address, and is considered a single device in the network. The communication interface
supports 3 network topologies:

Line topology

Star topology

Ring topology

Line Topology
2.6.2
In many applications, line topology enables simpler cabling and the use of fewer Ethernet switches. Observe network performance and
the number of devices in a line topology. Too many devices in a line may exceed network update time limits.
