when an alternative model is set.
Using an alternative model
*1. For Ver. 8.18U to 8.24A of GX Developer, the PLC type is FX3UC.
*2. "FX
2N" is selected when the FX-10P(-E) is used.
Contents of restrictions
• Programming is enabled only in the function ranges such as instruction/device range and program size
available in both the PLC model to be programmed and the alternative PLC model.
• In the FX
3S PLC, memory capacity setting of the PLC parameter must be set to 4,000 steps or less.
• Use a programming tool which can select FX
3S, FX3G, FX3GC, FX3U or FX3UC when changing the
parameters such as memory capacity and file register capacity.
• Use a programming tool which can select FX
3G when executing communication using the standard (USB)
built-in port of the FX
3S/FX3G/FX3GC PLCs.
