Industrial Bus Expansion IO System Adapted to KV-7000 PLC Master Station Modbus TCP for Data Collection and Control

BL200 series product is Edge I/O System for data acquisition and industrial control.

The system consists of two parts : Edge I/O controller and distributed I/O modules group.

Various types I/O modules are optional, for example digital, analog and others particular use. The Edge I/O controller supports various Fieldbus protocols such as Modbus, MQTT, OPC UA, Profinet, EtherCAT, BACnet etc.

he Edge I/O system is design based on powerful microprocessor 32-bit ARM926EJ-S™  and uses Linux operating system. It can quickly access to industrial field device and software (such as PLC, MES, SCADA and ERP systems), but also able connect to various cloud platforms (AWS IoT Cloud, Thingsboard, Ignition, Huawei Cloud, and Cloud).

It supports programmable logic control, edge computing, customization applications, very suitable for IIoT and industrial automation.

In addition, the device also provides SDK, allowing users to carry out secondary development to meet the needs of the fragmented applications in niche market.

In the industrial field communication, the edge I/O system is considered as a Fieldbus node. The communication between the node and field devices (eg PLC) is through the Ethernet port of Edge I/O controller. The communication between the edge controller and the I/O modules is via the board bus locally insides device.

The two RJ45 Ethernet ports of the BL200 have integrate the switch function inside, which can establish a linear topology without the need for additional switches or hubs.

Two sets of independent power supplies are used to supply 24V DC to the edge controller and I/O modules group respectively, therefore they are electrically isolated from each other.

When people assemble I/O modules, each I/O module can be arranged in any sequence combination. it is not required to be grouped by module type. However, a terminal module (identified as TERM) must be inserted at the end so as to ensure data transfer properly.

People can configure BL200 parameters through web browser for testing the device.

BL200 is especially suitable for distributed application scenarios, because BL200 can be cascaded with each other through Ethernet cables. various I/O modules can be distributed on different floors of different buildings in different locations according to user needs.

The whole system has the characteristics of easy expansion, easy configuration, convenient network wiring and high reliability,  can be widely used in

industrial automation/industry 4.0/smart factories,

smart building HVAC/smart parking lots/smart communities,

sewage treatment plants,

new energy power generation Factory (solar photovoltaic, wind power generation)
