Issue: 
What is the recommended replacement for the TWDLCAA24DRF Twido controller

Product Line:
All Twido Controllers

Environment:
TwidoSoft, TwidoSuite

Cause:
Product obsolescence of the entire line looking for the recommended PLC solution for this.

Resolution:
The recommended replacement for a TWDLCAA24DRF Twido controller is the TM221C24R controller, if you also want Ethernet the part would be TM221CE24R.

Characteristics Twido Reference vs Characteristics M221 Reference

Total I/O: 24 (Twido) vs 24 (M221)
Input: 14 (Twido) vs 14 (M221)
Relay Output: 10 (Twido) vs 10 (M221)
Trans Output: 0 (Twido) vs 0 (M221)
Analog Input: 0 (Twido) vs 2 (M221)
Power supply: 240VAC (Twido) vs 240VAC (M221)

Software Compatibility:
- SoMachine Basic Software could convert an application of Twido to M221 (except the function like Asi & CanOpen not supported by the M221)

Mechanical Compatibility:
- Same Width 70 mm & same Depth (Height) 90mm
- The M221Length is higher due to TB in 5.08 mm pitch vs TB in 3.81mm pitch on Twido
- M221 can support TM2 Digital & Analog IO module
- All module & accessory TWD*** are not supported by M221 in particular CanOpen, Asi, Serial Interface & display module.
- Twido + CanOpen Module = M241 CanOpen
- Twido + Asi Module = M221 Eth + Eth/Asi Gateway
