Atlas air compressorData AcquisitionGateway

1. Introduction

DAQ-GP-AMmodbus Gatewayis used to connect Atlas MK2, MK4 and MK5 computer controllers and convert the data of these controllers into standard ModbusRTU Protocol。 Through this Gateway, the operating status and parameters of the air compressor can be monitored, and the start, stop, loading, and unloading of the air compressor can also be controlled through serial communication. ThisGatewaycan connect 5 Atlas air compressors at the same time without additional configuration to form an air compressor group control network. The upper computer or PLC passes through RS485 Interface, using Modbus RTU Protocol, can interface with the network Real-time. The main parameters of DAQ-GP AMmodbus are as follows:

DAQ-GP AMmodbus compatible AC

The air compressor panel is as follows:

Support panel types

AC air compressorForm a "hand-in-hand" network, ultimately connected to the MKLAN interface of DAQ-GP AMmodbus, and the upper computer or PLC is connected through the Modbus interface.

2. Wiring

Connect the DB9 plug to the controller's LAN plug; The upper computer is connected to the "AB" terminal through a Modbus (485) cable;

Set the addresses on the controller panel to 1-10, and the corresponding Modbus slave addresses are 1-10;

When accessing the upper computer, collect data according to Modbus slave addresses 1-10, and use the table in Part 3 for the address table.

One to many connections
