• Set the data writing parameters (line position and column position) as follows.
- Line position of writing destination : K-1 (Additional writing)
- Column position : K1 (Head)
• When executed once, the FLWR instruction adds data by 1 line. It is not possible to additionally write data
which increases columns in to a previously written line position.
• The time stamp is added at the time of writing if the addition of the time stamp when writing has been set.
• After writing, the line position stores the following value
- Line position after writing : Line position next to the written line position
- Column position after writing : K1
Program Example
