2. Programming Concepts Notes: 1. Non-latched area cannot be modified 2. Latched area cannot be modified 3. Please refer to the table above for more information about serial ports. SX2 does not support I160. 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. 5. If the firmware version of an MPU is 2.0 or above, the MPU support the use of file registers. Please refer to the instruction MEMR/MEMW for more information about the reading/writing of data.
