6.5.2 Word Block Data Write (Client)
The following shows an example where the 262IF-01 acts as an FL-net message client to request a word block data
write with a data size of 100 words from a virtual address offset 0 to the remote device (node number 254).
( 1 ) MSG-SND Function Setting
The MSG-SND function is set as follows:
( 2 ) Parameter Setting
The parameter list from DA00000 is set as follows:
ΠFor register access method and notes at register input, refer to 6.4 Displaying a Register List and Notes at Register
Input on page 6-30.
When the Execute (DB000201) is set to ON (=1) from the above settings, the 262IF-01 sends a word block data write
request (transaction code: 65006).
Data of MW00000 to MW000511 (512 words) is read and written in the virtual address of a remote device for data size
of 512 words from offset 0.
When a word block data response (transaction code: 65206) is received from a remote device, COMPLETE in the
MSG-SND function goes ON for one scan.
ΠFor transaction codes, refer to 6.1.5 ( 5 ) PARAM05: Data Address on page 6-13.
