The PICPLC16 v6 development system provides a development environment for experimenting with industrial devices. Connection between the development system and these devices is established by means of relays. In addition, the PICPLC16 v6 features additional modules which also enable the microcontroller to be connected to external devices. The PICPLC16 v6 may be used as a stand-alone controller which communicates to remote devices through communication modules. Numerous modules, such as RS-232 communication module, real-time clock, ethernet controller, GSM module etc. are provided on the board and allow you to easily experiment with your microcontroller.
