CO401Mem1 is a memory module with CANopen bus interface. This allows saving parameters or data in a non-volatile memory within CANopen bus applications.

The CO40Mem1 provides  8kByte of EEPROM memory. The memory is organized in two parallel memory banks to guarantee very high redundancy. The memory is represented by multiple objects within the CANopen object dictionary.

The CO401Mem1 integrates the CANopen draft standard DS401 (simple I/O device).
Additionally to the CANopen interface the CO401Mem1 supports a serial interface with RS232-levels. This interface also provides complete access to the memory.

The module already has CAN transceiver (82C251) and serial RS232 transceiver on board, so only few external components are required.
