Key issues

Question 1: What is the most essential upgrade of FX3GE compared to regular FX3G, and what actual value does it bring to users?

Answer: The most essential upgrade is the standard configuration of 100M Ethernet+2AI/1AO analog. Value: No need to purchase additional communication and simulation modules, reducing costs, saving space, simplifying wiring, and supporting web monitoring for remote maintenance.

Question 2: What is the analog resolution of FX3GE? What signals can be directly supported and which scenarios are suitable?

Answer: Analog quantity 12 digits (0-4000); Supports 0-10V voltage and 4-20mA current signals; Suitable for simulating closed-loop control scenarios such as pressure, temperature, flow rate, liquid level, and speed regulation.

Question 3: What are the I/O expansion rules for FX3GE and how many points can it carry at most? Which old series modules are compatible?

Answer: Maximum 256 points (local 128 points+remote 128 points); Fully compatible with FX3G, FX3U, and FX2N digital, analog, and communication expansion modules, protecting existing equipment investments.
