TWLNOZ485T has no replacement. Serial interface adapters TWD NAC 485D/T provide 1 extra RS485 serial connection by Mini-DIN connector and screw terminals. If they are not available, you will need to migrate the Twido platform into the new controller M221. There is one additional serial link port on TM221MXXX controllers (RJ 45 connector) RS485. If TM221CXXX controllers are used, there is also 1 additional serial link on screw terminal block with communication cartridge TMC2SL1, however, only one communication cartridge can be applied even though there are maximum two cartridges for controllers with 40 I/O.
