3. DATA EXCHANGE WITH CPU
The F130 exchanges data with CPU using the following devices: High performance I/O unit relay
area (measurement value and hold value) and high performance I/O unit DM area (Initial setting
data).
Measurement value
・
Hold value
Analog signal from the strain gauge type sensor is converted into digital data.
Measurement
・
Hold data is allocated to one of the relay area of the CPU units’ high performance I/
O unit based upon the unit number. The data is exchanged regularly every time I/O refresh takes
place.
Initial setting data
Parameter settings for using F130 as a Loadcell Interface.
A set of initial setting data for each F130 is allocated, based on its unit number, to a DM area for
high performance I/O unit (inside CPU unit), and is written to this area when the unit is powered
on, or a refresh cycle is started.
