FAQ

Q1. What is GE's legacy in the industrial automation industry?
GE (General Electric), founded by Thomas Edison in 1889, was a global leader in PLC systems, including the famous Series 90-70, PACSystems RX3i/RXi, and VersaMax I/O platforms. While GE's industrial automation division was acquired by Emerson in 2019, these products remain widely used in factories worldwide .

Q2. Does GE support hot-swapping of I/O modules?

Yes, most GE PACSystems and VersaMax I/O modules support hot insertion (hot-swapping) when used with compatible Network Interface Units. This allows module replacement without powering down the entire system. However, always verify your specific NIU configuration before performing hot-swap .

Q3. What is the most common failure mode in GE PLC modules?

Power supply aging (capacitor failure) and communication faults (Ethernet/Profibus dropouts).
