Memory Display Image on PLC I/O
The memory display image on PLC I/O varies depending on the PLC to be used.
Using data output to the Data Output area of the PLC link from the serial data output processing item as an
example, this section illustrates how the memory display image varies depending on the model.
Data storage image (Data Output area DM1000)
When the PLC link Data Output area is set to DM1000, data is stored as follows in the PLC I/O memory.
*1: Up to 8 expressions can be registered in the serial output flow on the FZ4 side. If 8 expressions are registered, data is stored
as follows.

As an example, if 3 data items, expression 0 (DATA0) = 1.000, expression 1 (DATA1) = 200.000, and
expression 2 (DATA2) = 1000.000, are output from FZ4, they are stored to the PLC Link area as
measurement data as follows.
*1: Data is stored to the PLC I/O memory as follows for a decimal number per channel.
