these I/O ports.
User area
I/O ports in the user output area
Data that you defined for the
FH Sensor Controller is written
to these I/O ports from the
FH Sensor Controller.
*1: 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 Result Set Request signal to request the output data.
*2: Refer to Settings Required for Data Output (p.29) for information on the Output Units that output measurement data.
*3: Use the Macro Customization Function to input and output to the User Area.
For the Macro Customization Function, refer to
Macro Customize Functions Programming Manual (Cat. No. Z367).
