Program Plan Intro
Data Files:
- Data files include information needed to carry out user program such as timer and counter values, data storage, status of input and output devices, etc.
- Contents of data table can be divided into two categories such as status data and numbers or codes.
- The status data can be of either ON/OFF type and are stored in unique bit locations.
- Similarly, the numbers or codes can be represented by groups of bits that are stored in unique byte or word locations.
