Application Example
This example shows a program with the TRANSPARENT FRAME READ com-
mand.
Sample configuration The FINS 2902 command executes at the point indicated by this mark and the
PLC reads the transaction code that was received.
Operation • Set the TRANSPARENT FRAME READ command starting at D01000 in
the CPU Unit.
• Read the transaction code (100) and 10-byte data that was sent by node
address 2.
• Store the results of the reading starting at D02002. (The command code
is stored at D02000 and the response code is stored at D02001.)
