2.2 Software requirements
2.2.1 Components
FX Configurator FP Version 1.00 or later (optional, but needed of using this
document)
GX Developer Version 8.23Z or later
or GX IEC Developer Version 7.00 or later
3. Explanation of System Configuration
3.1 Memory configuration
The F3U-20SSC-H has two types of memory for initial data transfer processes and
continuous communication with servo equipment and programming devices. The
module’s flash memory retains parameter information and table data for initializing servo
equipment at power-ON while the buffer memory (BFM) constantly communicates with
servo equipment and PLC sequence programs. To set up positioning parameters, servo
parameters and table information for the F3U-20SSC-H, it is necessary to send data to
the module from a PLC sequence program or from FX Configurator-FP. Due to the
convenience and reduced complexity of program coding, FX Configurator-FP should be
used whenever possible to program table operations.
Below is a diagram of how the 20SSC-H memory communicates with servo amplifiers,
PLCs and other equipment.
