Specification of module number of FX3 intelligent function module and buffer memory
For FX3 intelligent function module connection method, number of connectable FX3 intelligent function modules and handling
of I/O numbers, refer to manuals of the CPU module and FX3 intelligent function modules.
• Module number of FX3 intelligent function module
Use the module number to specify for which equipment the RBFM/WBFM instruction is used. (Setting range: K1 to K16)
A module number is automatically assigned to each intelligent function module connected to the CPU module. The module
number is assigned as No.1
No.2
No.3… starting from the equipment nearest the CPU module.
• Buffer memory number
The intelligent function module incorporates a RAM memory. The RAM memory is called buffer memory. Buffer memory
numbers range from #0 to #32767 and their contents vary depending on the function of the extension equipment. (Setting
range: K0 to K32767)
For the contents of buffer memory areas, refer to manuals of intelligent function modules.
Error code
(SD0/SD8067)
