2.7.6 Special unit initial value setting [GX Developer Ver. 8.24A or later]
The initial values of the buffer memory (BFM) in special function blocks/units connected to an FX3U/FX3UC PLCs (Ver.
2.20 or later) can be set as a parameter in GX Developer (Ver. 8.24A or later).
When this parameter is used, it is not necessary to execute initial setting in a user program for special function blocks/
units requiring initial setting. The special unit initial value setting uses 4000 steps (8 blocks) in the memory capacity.
→ For the setting procedure, refer to Subsection 2.7.9.
→ For GX Works2, refer to the FXCPU Structured Programming Manual [Device & Common].
