: Node ID
On modules that do not have address switches the node ID can be selected using this object. On modules
with address switches the node ID is normally selected using the address switches. Only when the address
switches are set to an invalid value (0 or >127) this object overrides the address switch setting.
To change the node ID, first write the new node ID to this object. Then, store the new setting by writing the
save signature to object 2706
h
. After that, reset the module. The new setting then becomes active.
