Overview
DAM3370/S is a communication protocol conversion module that converts Modbus communication protocol to Profibus communication protocol. Before using this module, the GSD file needs to be installed first; After installing the GSD file, insert DAM-3370/S into the Profibus network: configure the parameters of the Profibus slave and Modbus master through the user parameter message configuration interface
Main Parameters
● Profibus/Modbus bus bridge
● Adopting the standard Modbus RTU Master communication protocol, supporting Modbus RTU Slave
● Profibus dp communication method, supporting multiple configuration software and PLC systems
● Communication speed: Profibus 9.6~6Mbps (customizable 12Mbps) Isolation type Modbus 1.2K~115.2Kbps Isolation type
● Communication port photoelectric isolation
● Power supply: unprocessed+10~+30VDC
Note: There are two sets of Profibus interfaces, one set uses terminal wiring, and the other set uses standard DB9 interfaces that can be connected using Profibus connectors. Choose one of the two.
How to choose?
When the upper computer is a PLC and the lower computer is a Modbus RTU device with RS485 interface, choose DAM3370
When the upper computer is a Modbus RTU device with RS485 interface and the lower computer is a PLC, choose DAM3370S
