2 LSS Modes

Devices that communicate with the LSS protocol can be in one of two modes,

‘Configuration Mode’ and ‘Operation Mode’. Any device on the network that is not in ‘Configuration Mode’ is in ‘Operation Mode’. In ‘Configuration Mode’ all LSS services are available. In ‘Operation Mode’ only the switch mode services are available.

Switching the mode of a device to ‘Configuration Mode’ must be explicitly initiated by the LSS Master. Mode switching is independent of the NMT state. With the exception of the LSS service ‘Configure Node-ID’ the NMT state of the device is not affected by LSS services.

If the Node-ID of the LSS Slave is changed with the LSS service ‘Configure Node-ID’, and the slave is switched back from ‘Configuration Mode’ to ‘Operation Mode’, a power-on like reset must be performed by the LSS slave; this affects the NMT state. For this reason the LSS-Master must reside on the same device that holds the NMT-Master.

2.1Configuration and the Operation Modes

An LSS Slave can be in one of two LSS modes:

Configuration Mode

ƒWhen an LSS Slave is in this mode, it actively listens for and processes configuration commands from the LSS Master.

ƒSome configuration commands configure only one LSS Slave at the time (for example, to change of CANopen node ID)

ƒSome configuration commands configure multiple or all LSS Slave nodes (for example, to change the baud rate)

Operation Mode

ƒAn LSS Slave in this mode ignores the configuration commands from the LSS Master.
