Flying Master Add-on

Dynamic NMT mode Master or slave

Configuration, monitoring, control of slave devices

[DeepL] sysWORXX CANopen Source Code

The extension module CANopen Flying Master implements a CANopen Manager according to CiA standard 302 Part 2 with the possibility to determine the NMT mode Master or Slave dynamically at runtime. In a CANopen network, only one CANopen device may be NMT master. This CANopen device controls the configuration of the slave devices, monitors these slave devices and is able to start or stop these slave devices.

To use the Add-On Module theCANopen Manager Stack is required.

Features / Details

In a CANopen network there can be several CANopen devices with the Flying Master. At the start of the network (power-on) all Flying Master devices negotiate among themselves which of these devices acts as NMT Master. This process is called NMT Flying Master Negotiation. The Flying Masters that do not act upon the NMT Master continue to operate as NMT Slaves and monitor the active NMT Master via the Heartbeat Protocol.

If the active NMT master fails (e.g. detection of a heartbeat timeout), NMT Flying Master Negotiation is restarted and the active NMT master is redefined among the remaining flying master devices.
