MiniPLC adopts the programming method with function blocks. 20 function blocks are configured in total, and each block can achieve a specific control function independently, e.g. time-delay ON, time-delay OFF, setting switch time, counter function, etc. As several blocks are linked up in a specific way, the relatively complicated control function can be realized. It will be more simple and apparent than the conventional PLC instruction programming.

The following types of operator for MiniPLC function blocks are available for options:
1. Options of input port: I1 - IC(Input port), Q1- Q8 (Output port), Moo-M126 (Intermediate relay), HI (High potential status), LO (Low potential status), X (No input connection), P0 - P9 (Telephone two-tone pulse)
2. Options for output port: Q1 ~ Q8 (Output port), Moo~M126 (Intermediate relay).
