Event E018


Qualified person

Event message:

  • PCS Offline

Explanation:

The system has not received any communication data from the power conversion system (PCS) within the specified time period and interprets this as a connection interruption to the PCS. This error prevents the system from cooperating with the PCS to perform charging/discharging operations and has triggered an error protection state.

Corrective measures:

  • Check the communication cables (e.g. CAN bus, Ethernet, RS485) between the device and the PCS. Make sure all connections are secure and check for loose, disconnected, or damaged interfaces.

  • Access the backend of both the system and the PCS device to ensure that the communication parameters (e.g., baud rate, device address, protocol version) are configured consistently.

  • Make sure that the PCS device is functioning normally and that its communication functions are intact.

  • After the physical connections have been repaired or the communication parameters adjusted, the communication connection is automatically restored and the error is resolved.
