A practical, engineer-honest guide for evaluating Kinco AK840M / K615S PLC, GL2070HE / GL2100E HMI, and KC200 / Kemron KV4800 VFD as migration candidates for selected Mitsubishi FX5U, FX3U, GOT2000, FR-E700, and FR-A800 applications. Includes SKU cross-reference, spec comparison, migration checklist, and a candid list of what Kinco does not replace.
Kinco AK840M and KC200 are cost-effective Mitsubishi FX5U/FX3U and FR-E700 alternatives for small-to-mid machine control and general-purpose drive applications, priced roughly 30-45% lower, supporting Modbus RTU/TCP, EtherCAT, and CANopen, and shipping ex-stock in 3-7 business days from Shenzhen. Best fit for standalone machines, conveyor lines, and pump/fan VFD retrofits; not recommended for multi-axis interpolation (>2 axes) or existing CC-Link IE fieldbus networks. Subject to engineering review.
Mitsubishi FX5U pricing has increased 12-18% since 2024 supply chain adjustments. For machines requiring 16-64 I/O points without advanced motion, the AK840M delivers equivalent control at 30-45% lower hardware cost — with KincoBuilder included free (GX Works3 is a separate $800-1,200 license).
FX5U and FR-E700 lead times from official Mitsubishi distributors frequently exceed 8-12 weeks in peak season. Kinco AK840M and KC200 ship ex-stock from Shenzhen in 3-7 business days for standard configurations, reducing project timeline risk.
GX Works3 requires a paid license per seat. KincoBuilder (CoDeSys V3.5-based) is free, supports the same IEC 61131-3 languages (Ladder, ST, FBD, IL), and includes EtherCAT network configuration — no additional software purchase.
Mitsubishi's proprietary CC-Link IE ecosystem creates deep lock-in. Projects that standardize on open protocols (EtherCAT, Modbus TCP, CANopen) gain multi-vendor flexibility for future expansions without re-engineering the fieldbus layer.
Kinco provides English-language manuals, datasheets, and application notes without regional access restrictions. Mitsubishi's download portal requires region-specific accounts and occasionally restricts access to certain document versions.

Seven steps for a structured Mitsubishi-to-Kinco migration. Effort estimates assume a single-cabinet, 32 I/O deployment by an experienced controls engineer.
Export Mitsubishi ladder logic from GX Works3. Recreate in KincoBuilder using CoDeSys Ladder or Structured Text. Standard ladder instructions map 1:1; Mitsubishi-specific instructions (PLSY, DSZR, ZRN) require equivalent CoDeSys motion function blocks.
The AK840M uses Phoenix MC 1.5 plug-in terminals versus Mitsubishi's proprietary spring-clamp block. All field wiring must be re-terminated. Estimated 2-4 hours per cabinet for 32 I/O points.
If replacing Mitsubishi GOT2000 HMI (GS2107/GT2510), HMI projects must be recreated in Kinco DTools. GT Designer3 project files cannot be imported. Modbus TCP address mapping must be reconfigured to match AK840M register layout.
Replace CC-Link IE with EtherCAT or Modbus TCP. Existing third-party devices on CC-Link require protocol gateways or replacement with Modbus-compatible alternatives.
Mitsubishi FR-E700 parameter numbers do not map to KC200/KV4800 parameters. Use the Kinco/Kemron parameter cross-reference guide (available from Automation Liberty engineering support) to translate frequency settings, acceleration ramps, and protection thresholds.
Bench-test each migrated cabinet with simulated I/O before field deployment. Validate scan cycle timing, analog accuracy, and communication response under load. Allow 1-2 days per cabinet for commissioning.
Update electrical drawings, PLC address lists, and HMI tag databases to reflect new hardware. Archive original Mitsubishi project files for reference.
Case study coming soon. We have documented migration deployments currently under customer NDA review. This section will be updated once authorization is received.
No — the AK840M-32DR uses a different terminal layout (Phoenix MC 1.5 plug-in, 32-point) versus the FX5U’s proprietary spring-clamp connector block. All 32 digital I/O channels map 1:1 in function (24V DC sourcing inputs, relay/transistor outputs), but field wiring must be re-terminated. Estimated 2–4 hours per cabinet for an experienced electrician. See the FX5U Hardware Manual section 3.2 for the original pinout.
Yes. The AK840M-32DR provides dual Ethernet ports (EtherCAT master + Modbus TCP) plus one RS485 port (Modbus RTU) active simultaneously. This enables EtherCAT servo control while communicating with legacy Modbus RTU devices (VFDs, sensors, meters) on the same program scan. CANopen is also available on the CAN port.
The AK840M is priced approximately 30–45% lower than the FX5U at equivalent I/O count (32-point). Exact pricing varies by order volume and configuration. The pricing advantage increases further when factoring in Mitsubishi’s GX Works3 license cost (charged separately) versus KincoBuilder (included free). Request a BOM-level quote for precise comparison.
Median lead time is 3–7 business days ex-stock from Shenzhen warehouse for standard AK840M and KC200 configurations. Custom I/O configurations or large batch orders (>50 units) may require 2–3 weeks. Stock status is confirmed at quote time — we do not quote items we cannot ship.
Mitsubishi GOT2000 HMI screens use a proprietary communication protocol (MC Protocol) that is not directly supported by Kinco PLC. However, if you configure the GS2107/GT2510 to communicate via Modbus TCP (supported by most GOT2000 models), it can talk to the AK840M. Screen projects (created in GT Designer3) cannot be imported into Kinco DTools — a new HMI project is required.
The AK840M is CE-marked (EN 61131-2), UL-listed, and CCC-certified. Operating temperature range is −20°C to +60°C. For applications requiring functional safety, the AK840M supports STO (Safe Torque Off) via integrated safety relay input per the IEC 61131-3 safety programming model. Full EMC test reports are available upon request.
Do not use the AK840M for: (1) multi-axis interpolation requiring >2 synchronized axes at >100 kHz — retain the FX5U or evaluate the Kinco F1/F2 Motion series; (2) existing CC-Link IE networks — the topology replacement cost exceeds 70% of a new build; (3) Q-series multi-CPU rack applications (Q06UDEHCPU and above) — Kinco does not manufacture rack-mounted multi-CPU PLCs. See the full limitations list above.
No. Kinco does not manufacture rack-mounted multi-CPU PLCs equivalent to the Mitsubishi Q series. The Q-series fiber-optic backplane, multi-CPU synchronization, and iQ-R inter-module communication have no Kinco equivalent. For Q-series applications, consider retaining the existing hardware, sourcing Mitsubishi refurbished units, or evaluating CoDeSys-based rack PLC platforms from other vendors.
KincoBuilder is a free IEC 61131-3 programming environment supporting Ladder, Structured Text, Function Block Diagram, and Instruction List. GX Works3 is a paid license (approximately $800–1,200). KincoBuilder supports CoDeSys V3.5 runtime with EtherCAT configuration, online monitoring, and simulation. The main gap: GX Works3’s integrated motion setup wizard and CC-Link IE configuration tool have no equivalent in KincoBuilder — motion setup is done via separate EtherCAT ESI files.
Kinco is headquartered in Shenzhen, China (SSE: 688160). Automation Liberty provides English-language engineering support for migration projects — BOM review, program translation, and commissioning guidance. First-line support response within 1 business day. On-site commissioning is available for deployments exceeding 10 cabinets (quoted separately).
All cross-references below are candidate replacements subject to engineering review. Pin compatibility, program migration, and application suitability must be validated per deployment.
