Product Features
ABB NCSA-01 can communicate with the master station via the CS 31 bus and with the variable frequency drive via the DDCS fiber optic link, enabling transparent data transmission between the two protocols.
ABB NCSA-01 supports bidirectional transmission of 1-3 data sets (each data set contains 3 16-bit data words), meeting different control requirements (default 1 data set, expandable via parameter configuration).
ABB NCSA-01 supports “Word Mode” (station numbers 0-5, shared station numbers require address indexing) and “Binary Mode” (station numbers 0-57, independent numbering), compatible with different CS 31 master station configurations.
ABB NCSA-01 provides real-time feedback on link status via 3 LED indicators (DDCS, UART, ERROR), such as DDCS fiber optic link failures, CS 31 bus errors, and hardware faults, facilitating quick troubleshooting.
ABB NCSA-01 features built-in terminal resistors that can be enabled/disabled via a switch, accommodating bus end installation requirements and reducing signal reflection.
ABB NCSA-01 supports reliable grounding, optical link electrical isolation, and electromagnetic interference resistance (compliant with EMC standards EN 50081-2 and EN 50082-2).
Product Using Principle
ABB NCSA-01 can receive control commands sent by the master station via the CS 31 bus, which are encapsulated in the data set in the form of “data words.”
ABB NCSA-01 can convert CS 31 protocol data into DDCS protocol format and transmit it to the variable frequency drive via a fiber optic link. The operating status of the variable frequency drive is transmitted back to the NCSA-01 via the DDCS link, converted into CS 31 protocol, and sent to the master station.
ABB NCSA-01 can monitor the status of the CS 31 bus and DDCS link via built-in circuits. If a hardware fault is detected, it triggers an ERROR LED alarm.
If the module is located at the end of the CS 31 bus, enable the terminating resistor to reduce signal reflection and ensure stable communication.
