ASGW is a component designed for Ethernet analyzer bus system. It is realized with the gateway software on
FCJ hardware. This system concentrates the Modbus accessed between multiple analyzers and DCS.
This system provides efficient engineering and communication performance.
ASGW has two type interfaces: Modbus TCP Ethernet one port and Mobus RTU serial.
Modbus mapping is realized with address table and programming is not necessary.
FCJ is described as ASGW is in this document.
