What replaces the TWD Analog and Discrete I/O modules?
The TWD modules are replaced by TM2 modules as listed in the tables below:
TM2 modules are supported by version 2.20 and above of TwidoSuite software. For other versions of TwidoSuite and all TwidoSoft versions, TM2 modules can be used, but the equivalent TWD module must be declared.
The new TM2 modules are compatible with the old TWD modules that they replace. A faulty TWD card can therefore be replaced by its TM2 equivalent without the need to modify the software configuration, regardless of which software is used.
The TM2 modules are discontinued and the replacement is the TM3 family range. In the next link you can find the catalog:

If you wanted a new or a replacement of the TM2 you are probably using a Modicon M238 , Twido or OTB. The new family range TM3 is not compatible with those devices.
If you share your architecture with the Technical Support they can suggest you a newer platform to migrate:
