3.5.5 MODBUS TCP Industrial Ethernet Communication
3.5.5.1 Overview
The Modbus TCP Industrial Ethernet adapter module (MD580–SI‑EM1 for short) meets
international Modbus TCP Industrial Ethernet standards. The module is used on the
MD580 series AC drive, so that the AC drive can work as a server on the Modbus TCP
Industrial Ethernet and be controlled by a Modbus TCP Industrial Ethernet client. This
effectively improves system communication efficiency and enriches the networking
functions of the MD580 series AC drive.
Features:
● Supports switch networking.
● Does not support IP address allocation using DPCH.
● Supports the minimum HMBT communication period of 6 ms.
● Supports reading of up to 124 parameters per time.
● Supports connection of up to two Modbus TCP clients. The minimum
communication period is doubled to 12ms when two clients are connected.
● Supports up to 100 m node‑to‑node transmission distance.
3.5.5.2 Electrical Connection
The MD580‑SI‑EM1 uses a standard Ethernet RJ45 socket for connection to the PC
background. The pin signal definitions are the same as those of the standard Ethernet
pins. It supports both crossover and straight‑through cabling modes.
