Object dictionary settings
The object dictionary settings contained in the module extension parameters are treated as CDCF for each setting target
node. (Including the settings for the own node)
When the power is turned on or the CPU module is reset, CDCF is saved into Concise DCF (index 1F22H, subindex 01H to
7FH) in the object dictionary of the RJ71CN91. ( Page 213 Concise DCF)
When the module extension parameters are saved after being changed, each node ID in the CDCF before change is
compared and the following processing is performed.
CDCF before change
The new node ID matches the node ID before change.
The new node ID does not match the node ID before change.
When the own node is the NMT master, if some unnecessary CDCF still remains, the configuration manager function may
operate to change the settings for other nodes. Therefore, to change the module extension parameters (node ID change or
node ID deletion), delete all CDCFs using CANopen Configuration Tool.
*1 All CDCFs can be deleted by using the [Restore Object Dictionary to default on all nodes] button in the "CANopen Configuration"
window.
