We have bought a new PLC (Model: TM221M16T, SV:1.10). We have connected the PLC to laptop with Schneider mini USB cable TQBMXXCAUSBH045. Ecostruxure software shows M221(USB) in local devices. But every time I try to login the PLC with ecostruxure software, it fails to login with advisory "Communication detection error, Verify USB cable, mod-bus driver parameters, controller connection, power supply."

Could you connect to an other TM221 controller?
Did you try to uninstall the USB driver and to reinstall ESME Basic?
For me it looks like an driver issue.
The connection should be possible through Mini USB it is not neccassary to supply the controler additional via 24V DC.
Please check if the drive would be recognized corectly at the windows device manager

The TM221 Controller is brand new. I don't have any other.
I tried MachineExpertBasic_V1.2_build65304 but still, not able to login. I reinstalled USB driver also, SchneiderPLCUSBDriverSuite V22.214.171.124. When I connect the controller, device manager shows M221 Controller. But still ecostruxure cannot login.
