Yueyang Tongtu is a professional supplier of the GE Fanuc PLC series, which is a classic modular programmable control system in the industrial field. It is characterized by high stability, long service life, and strong compatibility and expansion capabilities, covering micro, medium, and large-scale control architectures.
The mainstream includes VersaMax, 90-30, 90-70, RX3i, and RX7i five core series, which distinguish between small single-machine control, medium process control, and large redundant distributed control levels.
The entire series adopts an open backplane bus architecture and supports modular free combination of CPU, power supply, analog/digital I/O, high-speed counting, motion control, and communication modules.
This series has a large number of existing equipment that are in service in old heavy industries, energy infrastructure, and large-scale manufacturing production lines, belonging to an industrial super-long life cycle industrial control system.
Unlike the new lightweight PLCs, the GE FANUC industrial control hardware focuses on industrial-grade conservative design, resisting power grid fluctuations, electromagnetic interference, and supporting 24-hour uninterrupted continuous operation, suitable for long-term operation, expansion, and spare parts replacement scenarios of old systems.

• Support old software and hardware, support equipment retrofit and renovation, significantly reducing upgrade costs.
Q1: Can the old GE Fanuc PLC modules be mixed and networked across different series?
A: It is not recommended. Different series have different bus protocols and backplane architectures, and mixing them can easily cause networking failures and program abnormalities.
Q2: Is the stability of the dismantled module reinstallation guaranteed after it is discontinued?
A: All dismantled modules have undergone full functional aging tests and are selected after passing the screening process before being delivered. They can stably adapt to industrial continuous operation conditions.
Q3: Can CPUs from different hardware batches be directly replaced?
A: The firmware version needs to be checked. Some old programs are not compatible with the new version of the CPU. We will conduct a version adaptation assessment in advance.
Q4: Is the GE Fanuc PLC suitable for high-speed and precise motion control scenarios?
A: Basic motion control can be adapted. For ultra-high precision and high-speed scenarios, it is recommended to optimize with dedicated motion modules.
Q5: Does the expansion of an old system require rewriting the program?
A: Compliance replacement of modules of the same specification does not require rewriting the program. We can provide expansion adaptation guidance.
Q6: Can long-term spare parts reserve services for discontinued modules be provided?
A: Yes, we can provide customized long-term spare parts stocking plans based on the factory's operation and maintenance needs.
Q7: Can complete and compliant acceptance documents be provided for overseas projects?
A: We can provide test reports, traceability materials, and customs declaration documents, which are suitable for overseas project review and acceptance.
