Overview and Specifications

Overview

The Modbus protocol is a communications protocol that is based on a client-server architecture. It was created in 1979. In the industry, Modbus has developed into a de facto standard since it is an open protocol.

Modbus allows connecting a server and several clients, usually via Ethernet. Three different operating modes are differentiated for data transmission: Modbus ASCII, RTU and TCP.

Each bus participant must have a unique address. In this case, the address 0 is reserved for a broadcast. Each participant may send messages via the bus.

Kollmorgen AKD Drive offers the TCP mode Modbus. TCP/IP packets are used to transmit the data. The TCP port 502 is reserved for Modbus TCP.

Note: The AKD-P-NxPN (Profinet) drive is the only AKD model in the family that does not support Modbus TCP communications.
