About the G-series System

Overview

Network Adapter Module – The network adapter module forms the link between the field bus and the field devices with the expansion modules. The connection to different field bus systems can be established by each of the corresponding network adapter modules, e.g., for MODBUS TCP, Ethernet IP, EtherCAT, PROFINET, CC-Link IE Field, PROFIBUS, CANopen, DeviceNet, CC-Link, MODBUS/Seria,l etc.
Expansion Module – Expansion module types: Digital IO, Analog IO, and Special modules.

Messaging – The system uses two types of messaging: Service messaging and IO messaging.

IO Process Data Mapping

An expansion module has three types of data: IO data, configuration parameter, and memory register. The data exchange between the network adapter and the expansion modules is made via IO process image data by internal protocol.

Data flow between network adapter (63 slots) and expansion modules
The input and output image data depend on the slot position and the data type of the expansion slot. The ordering of input and output process image data is based on the expansion slot position. Calculations for this arrangement are included in the manuals for networadapterser and programmable IO modules.

Valid parameter data depends on the modules in use. For example, analog modules have settings
of either 0-20 mA or 4-20 mA, and temperature modules have settings such as PT100, PT200, and PT500.
The documentation for each modudescribes of the parameter data.
