9. Creating Programs (FX3S, FX3G, FX3GC, FX3U, FX3UC)
This chapter explains how to create programs which change parameters of inverters and give operation
commands to inverters.
As explanation, a program example is shown for each applied instruction.
9.1 Differences between FX2N, FX2NC and FX3S, FX3G, FX3GC, FX3U, FX3UC
Instruction devices used in inverter communication are different between FX3S, FX3G, FX3GC, FX3U, FX3UC
PLCs and FX2N, FX2NC PLCs.
When using a program for FX
2N, FX2NC PLCs in FX3S, FX3G, FX3GC, FX3U, FX3UC PLCs, change the devices
according to the tables below.
1. Inverter communication instructions
*1. Only available for FX3U and FX3UC PLCs.
2. Related devices
1) Bit devices
*2. In the FX
2N and FX2NC PLCs, M8063 does not turn ON when an inverter communication error occurs.
*3. Cleared when the PLC mode is changed from STOP to RUN.
*4. The IVBWR instruction is supported only in FX
3U and FX3UC PLCs.
*5. Cleared when PLC power supply is turned from OFF to ON.
2) Word devices
*6. Cleared when PLC power supply is turned from OFF to ON.
*7. Cleared when the PLC mode is changed from STOP to RUN.
*8. The IVBWR instruction is supported only in FX
3U and FX3UC PLCs.
