Function and positioning

This module serves as the multi-protocol network core expansion unit of SYSTEM 2005 PLC, integrating dual CAN buses and RS232 interfaces, achieving parallel and redundant communication of multiple buses. Both CAN-Bus interfaces are electrically isolated, supporting CAN 2.0A/B and CANopen master/slave stations, with a maximum of 500kbps per path. It can build redundant CAN networks or connect multiple CANopen servo, frequency converters, and remote I/O. The RS232 interface can be configured as an online debugging or data transmission interface, connecting to the upper computer or serial port terminal to achieve program download, monitoring, and data interaction. Interconnections between interfaces and between interfaces and the system bus are electrically isolated, with strong anti-interference ability; supports hot swapping, maintenance without power-off; configured through Automation Studio for CAN baud rate, node address, and RS232 parameter settings, suitable for redundant CAN networks, multi-CAN device networking, serial port online debugging, and upgrading of old equipment to multiple protocols.
