The only thing I can think of is in reference to the memory used by the system. Here is th formula: # of controller tasks *4000= _______bytes (min. 1 task per controller) # of digital I/O points *400= ________bytes # of analog I/O points *2600=_________bytes # of communication cards *5000= _________bytes count all communications module, not just the ones in the local chassis Add them up and you get estimated memory usage. The 1794-L33 CPU has 64 K memory; the 1794-L34 CPU has 512 k memory.
