*1: The Response Area (3) and Data Output Area (4) are assigned to continuous memory addresses or to variables.
*2: You can use output controls (handshaking) to prevent output data from being externally output from the communications buffer
until the Controller (master) turns ON the DSA signal to request the output data.
*3: Refer to Settings Required for Data Output (p.29) for information on the Output Units that output measurement data.
*4: Use the Macro Customization Function to input and output to the User Area.
For the Macro Customization Function, refer to
FZ5 Macro Customize Functions Programming Manual (Cat. No. Z367).
