Frequently Asked Questions
Q: Is the FX2N-128MR-001 still in production by Mitsubishi Electric?
A: The FX2N Series has reached end-of-production status from Mitsubishi Electric. However, new-in-box and refurbished units remain available through authorized aftermarket channels. Konmask.com maintains stock and sourcing capability for this model. Contact us for current availability.
Q: What is the difference between FX2N-128MR and FX2N-128MT?
A: The “MR” suffix denotes relay output, while “MT” denotes transistor (NPN) output. Relay outputs are suitable for AC and DC loads with higher current capacity per point; transistor outputs offer faster switching speeds ideal for pulse output and high-frequency applications.
Q: Can the FX2N-128MR-001 communicate with third-party HMIs or SCADA systems?
A: Yes. Via the built-in RS-422 port and optional communication boards (RS-232, RS-485, Ethernet), the FX2N-128MR-001 supports Modbus RTU, MC Protocol, and various third-party driver integrations compatible with Wonderware, Ignition, and other SCADA platforms.
Q: What programming software is required?
A: The FX2N-128MR-001 is programmed using Mitsubishi GX Developer or GX Works2 software. Both support ladder diagram (LD), instruction list (IL), and structured text (ST) programming environments.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a warranty period on all supplied units. Specific terms depend on unit condition (new/refurbished) and are stated in the quotation. Please contact us for details.
