MN1941WEN Troubleshooting 6-7
The Manager node cannot scan/recognize a node on the network using the Mint
NODESCAN keyword:
Assuming that the network is working correctly (see previous symptoms) and the bus is in an
‘Operational’ state, check:
Only nodes that conform to DS401, DS403 and other ABB CANopen nodes are
recognized by the Mint NODESCAN keyword. Other types of node will be identified with a
type “unknown” (255) when using the Mint NODETYPE keyword.
Check that the node in question has been assigned a unique node ID.
The node must support the node guarding process. NextMove e100 does not support
the Heartbeat process.
Try power-cycling the node in question.
If the node in question does not conform to DS401 or DS403 and is not a ABB CANopen
node, communication is still possible using a set of general purpose Mint keywords. See the
Mint help file for further details.
The node has been successfully scanned / recognized by the Manager node, but
communication is still not possible:
For communication to be allowed, a connection must be made to a node after it has been
scanned:
ABB controller nodes are automatically connected to after being scanned.
Nodes that conform to DS401, DS403 must have the connections made manually using
the Mint CONNECT keyword.
If a connection attempt using CONNECT fails then it may be because the node being
connected to does not support an object which needs to be accessed in order to setup the
connection.
