3. Replacement of FX2NC series
3.1 Outline
The production of the FX2NC series main unit and certain expansion equipment will be terminated in
September 2012.
The repair service period will end at the end of September 2019.
The procedure to replace the FX
2NC series with its successor, the FX3UC series, is outlined here.
3.1.1 Cautions
(1) “Recommended replacement models” lists the most tting FX3 series product based on specication
comparison. Depending on operation environment or the system conguration (connection status of
expansion equipment), or when the number of inputs and outputs in use is smaller, other products may
be more appropriate than the recommended replacement model.
(2) Recommended replacement models for extension blocks, extension units, special function modules,
expansion boards, and batteries are selected based on compatibility with current FX3 series main units.
(3) Pay close attention to notes marked as “Special remarks.” For attributes such as external dimensions,
there can be slight differences between the recommended replacement model and existing product.
Before performing replacement, be sure to review other relevant details such as dimensions, and power
supply requirements.
(4) For instances where there is no recommended replacement model, a message stating “No recommended
replacement model” will be shown. In this case, a FX3 series system may still be able to provide
equivalent operation.
Evaluate the requirements of the application and use a FX3 series system conguration for replacement.
