Chapter 4 PROFINET communication card

4.1 Overview

1. Thanks for choosing INVT PROFINET communication cards. This manual describes the
function specifications, installation, basic operation and settings, and information about
the network protocol. To ensure that you install and operate the product properly, read
this manual and the communication protocol section in the VFD operation manual
carefully before you use the product.
2. This manual only describes how to operate the PROFINET communication card and the
related commands but does not provide details about the PROFINET protocol. For more
information about the PROFINET protocol, read the related specialized articles or books.
3. This communication card is defined as a PROFINET slave station communication card
and is used on a VFD that supports PROFINET communication.
4. The communication card supports the linear network topology and star-shaped network
topology.
5. The communication card supports 32 inputs/outputs to read and write process data, read
state data, and read and write function parameters of a VFD.

4.2 Features

1. Supported functions
 Supports the PROFINET protocol, and supports PROFINET I/O devices
 Provides two PROFINET I/O ports and supports the 100 M full-duplex operation
 Supports the linear network topology and star-shaped network topology.
2. Supported communication types
 Standard Ethernet channels
Standard Ethernet channels are non-realtime communication channels that use the
TCP/IP protocol, and are mainly used for device parameterization and configuration
and to read diagnosis data.
 Real-time (RT) communication channels
RT channels are optimized channels for real-time communication. They take
precedence over TCP (UDP)/IP, which ensures that various stations on a network
perform data transmission with high time requirements at a certain interval. The bus
period may reach the precision of millisecond. These channels are used to transmit
data such as process data and alarm data.
 Isochronous real-time (IRT) communication channels
IRT channels are implemented through the built-in Switch-ASIC IRT chip. IRT
