The CLICK CPU module can store up to 8,000 steps (instructions) of ladder program in its flash EEPROM memory.

• All program documentation is downloaded to the PLC with the ladder logic. This is especially useful if you find yourself editing the program with a different programming PC in the future.
  
  
• The ladder program can be organized into subroutines with no limit on the number of subroutines other
  than the total available memory.
  
  
• Up to 8 Interrupt routines can also be defined, and can be initiated based on a time interval or via the
  8 physical inputs on the CPU module.
