Set Node Guarding / NMT Slave Assignment

Nodes can be easily set to Guarding-Master or Guarding-Slave status by writing values to Index H1F81 using
the Command Interface (CIF). The parameters for guarding are included in the information that can be written
to the CAN bus.
The module needs to be NMT Master to use these functions.
Note
• If the node number to be guarded exceeds the range K1 to K127, the corresponding BFM will display the
value which caused the problem.
• The FX -CAN module may write a value of HFFFF to the "Slave configuration" parameter of a node that
3U
has a parameter configuration error.
• The FX -CAN module may write a value of HFFFF to the "Guard Time" parameter of a node that has a
3U
parameter configuration error.
• If the "Retry Factor" parameter exceeds 255, an error value will be displayed in the corresponding BFM.
• The FX -CAN module may write a value of HFFFF to the "Retry Factor" parameter of a node that has a
3U
parameter configuration error.
• If the node number, slave configuration, retry factor and guarding time is just copied to the corresponding
result BFM, the remote node does not support Index H100C (guarding time)/H100D (retry factor). In this
case, the remote node cannot detect a missing guarding request of the network master.
Execution procedure: Set Node guarding/NMT Slave Assignment
1) Write the Slave number, Slave Configuration, Guard Time and Retry of the target node to BFM #1001 to
#1064. Set the Node-ID of the configured NMT Slave to Slave number. For the setting value of the Slave
Configuration, Guard Time and Retry Factor, refer to the following section.
Write HFFFF to the Slave number following the last target node to complete "Node guarding/NMT slave
assignment" settings.
2) Write the command code H8400 to BFM #1000.
When the command code H8400 is written to BFM #1000, the command is executed.
3) When the executed command is successful, H8401 is written to BFM #1000.
→ If H740F, H000F or HFFFF is read from BFM #1000, refer to Section 10.9
