Creating Programs4-224.3.4 Status Information (12-bit mode)With the analog output unit, the following information can be monitored in the external inputarea WX. Status informationI/O No. DescriptionX20 Analog output unit power 0: OFF, 1:ON、X21-X23 Used in the systemX24 CH0 data writing status 0:Normal, 1:Error (Note 1)An error occurs when data written to the memory area (WY2/WY3) isout of each range, and the data conversion is not performed. Theerror is cleared when data within the range is written and theconversion is performed.X25 CH1 data writing statusX26 CH2 data writing statusX27 CH3 data writing statusX28-X2F Used in the system(Note 1): Output data and output CH switch flag are allocated to the same I/O number. Data error can be detectedsuccessfully with the flags when the digital input value is within the range of K-4096 to K4095.Even when the digital input value is out of the range, however, data conversion may be mistakenly conducted.To prevent this problem, be sure to set up the program to check the upper and lower limits of the digital value.
