Each of the selections in a signal module can comprise the following data types:
· Boolean
· Unsigned 8/16/32
· Signed 8/16/32
· Float 32
The buffer size adapts to the data type of the selected 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.

2.5.1 Functional Extension Options
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.

2.6 Network Topologies
Communication interface X1/X2 is used for fieldbus connection. The iC7 series communication interface 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
2.6.1 Line Topology
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.

Product Overview

NOTICE

When line topology is used, take precautions to avoid timeout in the PLC when more than 8 drives are installed in series. Each drive in the network adds a small delay to the communication due to the built-in Ethernet switch. When the update time is too short, the delay can lead to a timeout in the PLC.

– Set the update time as shown in the table. The numbers given are typical values and can vary from installation to installation.

e30bk812.10

Illustration 3: Example of Line Topology
NOTICE
Installing drives of different current ratings in line topology may result in unwanted power-off behavior.
– Mount the drives with the longest discharge time first in the line topology. In normal operation, the drives with bigger cur-
rent ratings have a longer discharge time.
2.6.2 Star Topology
In a star network, all devices are connected to the same switch or switches. Star topology reduces the damage caused by single cable failure. In a star topology, a single cable failure affects a single drive instead of all drives. In many applications, this topology enables simpler cabling depending on the location and distance of the device.

Illustration 4: Example of Star Topology

2.6.3 Ring Topology
Ring topology enables the same simpler cabling and reduced cabling costs as line topology, but also reduces the damage caused by a single cable failure in a similar manner as star topology.

NOTICE

When line topology is used, take precautions to avoid timeout in the PLC when more than 8 drives are installed in series. Each drive in the network adds a small delay to the communication due to the built-in Ethernet switch. When the update time is too short, the delay can lead to a timeout in the PLC.

– Set the update time as shown in the table. The numbers given are typical values and can vary from installation to installation.

Not recommended

The ring topology protocol depends on the protocol in use.
For PROFINET, the Media Redundancy Protocol (MRP) is used. The MRP is designed to react deterministically on a cable failure. One of the nodes in the network has the role of Media Redundancy Manager (MRM), which observes and controls the ring topology to react to network faults. Usually this device is a PLC or network switch.

3.2.1 Grounding
· Ensure that all stations connected to the fieldbus network are connected to the same ground potential. When distances between the stations in a fieldbus network are long, connect the individual station to the same ground potential. Install equalizing cables between the system components.
· Establish a grounding connection with low HF impedance, for example, by mounting the drive on a conductive backplate. · Keep the ground wire connections as short as possible.
3.2.2 Cable Routing
NOTICE
EMC INTERFERENCE Failure to isolate fieldbus communication, motor, and brake resistor cables can result in unintended behavior or reduced performance.
– Use shielded cables for motor and control wiring, and separate cables for fieldbus communication, motor wiring, and brake
resistor.
– Minimum 200 mm (7.9 in) clearance between power, motor, and control cables is required. For power sizes above 315 kW
(450 hp), increase the minimum distance to 500 mm (20 in).

NOTICE
