11.2 Diagnostic messages to the S7 controller
Cause of error and possible solution
Received and sent CAN messages may have
been lost.
Check for communication problems caused by
EMI. If these can be excluded, there may be a
hardware fault and the module must be
replaced.
No heartbeat message has been received from
the node within the specified time or the node
has not responded to a node guarding request
within the set monitoring time. If the message
occurred during startup, the start procedure is
repeated for all nodes. In all other cases the
reaction configured under "Reaction to failure
of node" is executed.
The node signals an unexpected network
status (NMT status).
Signaled NMT status {1:x}.
If the message occurred during startup, the
start procedure is repeated for all nodes. In all
other cases the reaction configured under
"Reaction to failure of node" is executed.
Errors were detected when starting the node.
Details are output in one or more additional
diagnostic messages.
Depending on the "Node is mandatory on the
network" setting, the node is restarted or all
nodes are restarted.
The node has not responded to a request (OD
1000) for 30 seconds.
Check whether the node is correctly connected
to the CAN bus and that it is not in "Stopped"
state.
The start operation is continued.
-
During startup no heartbeat or node guarding
message was received from this node within
the specified time.
The device type ID ({1:x}) of the node differs
from the configured device type ID.
Check whether the correct device is connected
and the right EDS file was loaded. If the device
type ID is 0, the ID could not be read by the
device.
The Manufacturer ID ({1:x}) of the node differs
from the configured Manufacturer ID.
Check whether the correct device is connected
and the right EDS file was loaded. If the
Manufacturer ID is 0, the ID could not be read
by the device.
