2. Programming Concepts Notes: 1. Non-latched area cannot be modified 2. Latched area cannot be modified 3. COM2: built-in RS485 port. COM3: built-in RS485 port. 4. The PLC occupies 16 input points (X0~X17) and 16 output points (Y0~Y17). The extension input point starts from X20 and extension output point from Y20.
