PRE-OPERATIONAL

t: Toggle bit. The value of this bit must alternate between two consecutive
responses from the NMT Slave. The value of the Toggle bit of the first response
after the Node Guarding protocol becomes active is 0. The Toggle bit in the
Node Guarding protocol is only reset to 0 when reset_communication is passed
(no other change of the state resets the Toggle bit). If a response is received
with the same value of the Toggle bit as in the preceding response then the new
response is handled as if it was not received.

The NMT Master polls each NMT Slave at regular time intervals. This time-
interval is called the guard time (see the

100C-00 Guard time

object) and may

be different for each NMT Slave. The response of the NMT Slave contains the
state of that NMT Slave. The

node life time

is given by the

100C-00 Guard

object value multiplied by the

100D-00 Life time factor

object value. The

node life time can be different for each NMT Slave. If the NMT Slave has not
been polled during its life time, a remote node error is indicated through the
'Life Guarding Event' service.
A remote node error is indicated through the 'Node guarding event' service if:

•

the remote transmit request is not confirmed within the node life time;

•

the reported NMT Slave state does not match the expected state.

If it has been indicated that a remote error has occurred and the errors in the
guarding protocol have disappeared, it will be indicated that the remote error
has been resolved through the 'Node Guarding Event' and 'Life Guarding Event'
services.

At system boot the “Node guarding protocol” is disabled; this protocol is enabled
automatically as soon as the Master device sends an RTR message (Remote
Transmission Request) the first time.
