6.5.3 Word Block Data Read/Write (Server)
The following shows an example where the 262IF-01 acts as an FL-net message server to handle a word block data
read or write request with a data size of 10 words from a virtual address offset of 100 from remote device.
( 1 ) MSG-SND Function Setting
The MSG-RCV 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.
In the above setting, setting Execute (DB000201) to ON (=1) causes a waiting state for reception.
When a word block data read request (transaction code: 65005) is received from a remote device, the 262IF-01 sends a
word block data read response (transaction code: 65205). At this time, data in MW00100 to MW000109 (10 words) is
read.
When a word block data write request (transaction code: 65006) is received from a remote device, the 262IF-01 sends
word block data write response (transaction code: 65206). At this time, data with a data size of 10 words is read from
virtual address offset 0 of the remote device and written to MW00100 to MW000109 (10 words) of the 262IF-01.
The virtual space address data size specified in the request message is stored in the data address (DW00005 and
DW00006).
ΠFor transaction codes, refer to 6.1.5 ( 5 ) PARAM05: Data Address on page 6-13.
