The SETLED command is not implemented in the M-series PLCs and there is no plan to add such peripherals.

However, you could drive a 7-segment LED using the PLC's digital output port. But you will need 8 outputs to drive a single digit of 7 segment LED (plus decimal point is 8). If it very easy to use TBASIC to output the output bit combintation to display 0-9 on the 7 segment display.
