Initialization

FINS messages
Ending
The basic procedure for using the message service is outlined in the following
flowchart.
Routing tables
already written
Write the routing tables using the
Support Software.
Transfer the routing tables to the
other nodes using the Support
Software. (Routing tables transferred
to the Board will be recorded in the
Board's EEPROM memory.)
Open the application interface using
the ClkOpen function.
Send FINS message using the
ClkSendFins function.
Check for responses to FINS message
using the ClkRecvFins function.
Close the application interface using
the ClkClose function.
Note 1. Routing tables are not needed if all communications take place with other
nodes in the local network, but routing tables must be prepared if there are
communications between nodes on different networks.
2. Repeat the process to send and receive FINS messages as often as re-
quired by the application.
3. To used Windows-based messages to determine if a FINS message has
been received, use the ClkSetMessageOnArrival and ClkSetThreadMes-
sageOnArrival functions to register the Windows-based messages to be
used for notification. When not using Windows-based messages, check pe-
riodically for FINS messages using ClkRecvFins.
