PIC-IO board was designed as simple platform which to allow control of appliances and Industrial Automation with PIC, the idea was to build something like tiny PLC controller which is possible to program in C or assembler instead of the weird PLC relay language , If you need use Ladder Logic You can use This Software LD Micro Or FLOW CODE.
