Canopen to modbus development

The embedded module can be used for TTL connection with the original serial port equipment, or 232/485 connection, so that the original serial port equipment has Canopen communication capability, and Canopen transfer Modbus products can also be developed.

The serial port is the main station of Modbus RTU, at Canopen end for Canopen from the equipment.

From the station communication module, the inside has integrated CANopen from the station protocol stack code, no

2 developments are needed. The protocol stack follows The CANopen protocol description documents DS301, DS302, DS303, and DS305 standards.

The module has the following characteristics.

Z network management service objects (NMT: Boot up, Node, Guarding, / Life, Guarding, Heartbeat)

Producer);

Z process data objects (TPDO and RPDO);

Z service data object (SDO server/SSDO);

Z emergency message object (emergency);

Z synchronous message object (Sync);

Z network configuration object (LSS slave station);

Z CAN bus supports the baud rate of 10Kbps ~ 1Mbps;
