Ethernet IO Module export China

BL202 coupler is a data acquisition and control system based on a powerful 32-bit microprocessor design with a Linux operating system.

The BL202 distributed I/O system consists of 3 parts: Coupler, I/O modules and terminal modules.

The communication between the node and the field devices (eg PLC) takes place via the Ethernet interface of the fieldbus coupler, and the communication between the fieldbus coupler and the I/O modules takes place via the local bus.
