FX3U and FX2N
What is the difference between the 2 wire system and the 4 wire system when 3U and 2N PLC communicate with 485BD boards?
The difference between FX2N-4AD and FX3U-4AD
FX2N-4AD and FX3U-4AD? Is the FX2N series PLC only FX2N-4AD, while the FX3U series PLC can be both FX2N-4AD and FX3U-4AD? What are the specific differences between the two?
Thank you
