Synchronization of link scan and user programs
The routine of a user program can be executed in sync with the operations of a link scan of cyclic transmission.
Execution of routine synced with a link scan
A user program synced with a link scan is executed by registering a routine to be called automatically at the completion of a
link scan.
Registration and clearing of routines
Use the C Controller module dedicated function (CCPU_EntryLinkScanEndFunc) to register routines.
After registration, the registered routine is repeatedly called each time a link scan is completed. When NULL is specified to a
routine to be registered, the routine is deregistered.
• During CC-Link IE Field Network synchronous communication
Registered routines are called at the following timing during CC-Link IE Field Network synchronous communications.
