Chapter 4 PROFINET communication card
4.1
Overview
1. Thanks for choosing ASTRAADA 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.

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 communication can
further shorten the processing time of the communication stack software, synchronizing data
transmission of the program and device. The transmission delay is less than 1 ms, and the jitter is less
than 1 μs. The typical application is motion control.
3. Communication ports
Standard RJ45 ports are used in PROFINET communication. The communication card provides two RJ45 ports
with no transmission direction defined, and therefore you can insert a cable into the port without regard to
its direction.
Figure 4-1 shows the ports, and Table 4-1 describes the functions of the ports.
