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.
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.

NOTE
To support encoders with no differential signal i.e. only A+ and B+ channel without A- and B-, then connect A- and B- to the field power 0V. The reason for this is that A+ and B+ receive the signals output from the encoder, while A- and B- serve the role of establishing the reference voltage for the input signals, making their connection essential.

Gate Mode (Gate Function)
The gate function operates in one of the following modes:
- Store / Continue
- Store / Wait / Resume
- Store-reset / Wait
- Store-reset / Start
Store / Continue
When G ph are raising edge, the stored count value register will get counting value by current count value register. Next current count value will do counting continue. Below example picture shows timing waveforms of Store / Continue.
Store / Wait / Resume
When G Ph are rising edge, the stored count value register will get counting value by current count value register, and waits the current count value until falling edge. Next G Ph will be filling edge and current count value register resume counting. Below example picture shows timing waveforms of Store / Wait / Resume.
Store-reset / Wait / Start
When G Ph are rising edge, the stored count value register will get counting value by current count value register and current count value register reset at the same time. The current count value register waits until G Ph falling edge. Next current count value register start counting. Below example picture shows timing waveforms of Store-Reset/Wait/Start.
Store-reset / Start
When G Ph are rising edge, the stored count value register will get counting value by current count value register, and current count value register reset at the same time and the register start counting. Below example picture shows timing waveforms of Store-reset / Start.
Hardware Setup
CAUTION
- Always read this chapter before installing the module!
- Hot surface! The surface of the housing can become hot during operation. If the device is used in high ambient temperatures, always let the device cool down before touching it.
- Working on energized devices can damage the equipment! Always turn off the power supply before working on the device.
Space Requirements
The following drawings show the space requirements when installing the G-series modules. The spacing creates space for ventilation, and prevents conducted electromagnetic interference from influencing the operation. Installation position is valid vertical and horizontal. The drawings are illustrative and may be out of proportion.
CAUTION
NOT following the space requirements may result in damaging the product.
