ABSTRACT The Paper presents design and development of a CPLD based wireless telecommand system simulating industrial plant automation, wherein master controller remotely controls the relays/ sensors. Transmitting end comprises of RF module and a CPU hosting a LabVIEW based virtual instrument. Front Panel of the virtual instrument consists of 4 switches, few controls to configure COM port and SEND button. Pressing the SEND button would transmit the status of 4 switches through RF module, interfaced to PC through COM port. Receiving end comprises of RF module and a CPLD development kit. CPLD hosts VHDL code to receive the transmitted string, decode the command and display the command on the LEDs/ monitor and operate a relay
