WARNING
· Do not assemble the products and wires with power connected to the system. Doing so cause an “arc flash”, which can result in unexpected dangerous events (burns, fire, flying objects, blast pressure, sound blast, heat).
· Do not touch terminal blocks or IO modules when the system is running. Doing so may cause electric shock, short circuit or malfunction of the device.
· Never let external metallic objects touch the product when the system is running. Doing so may cause electric shock, short circuit or malfunction of the device.
· Do not place the product near inflammable material. Doing so may cause a fire. · All wiring work should be performed by an electrical engineer. · When handling the modules, ensure that all persons, the workplace and the
packing are well grounded. Avoid touching conductive components, the modules contain electronic components that may be destroyed by electrostatic discharge.
CAUTION
· Never use the product in environments with temperature over 60. Avoid placing the product in direct sunlight.
· Never use the product in environments with over 90% humidity. · Always use the product in environments with pollution degree 1 or 2. · Use standard cables for wiring.

3. About the G-series System
About the G-series System
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 module, e.g., for MODBUS TCP, Ethernet IP, EtherCAT, PROFINET, CC-Link IE Field, PROFIBUS, CANopen, DeviceNet, CC-Link, MODBUS/Serial 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.

About the G-series System
3.1. 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 network adapter 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 module provides a description of the parameter data.
