Resolution
On the Memory TAB for a discrete or analog Input modules, the starting input is set to 1. So %I0 and %IW0 are not used.
  • For inputs in Bit format: %I-1x - starts at %I1
  • For inputs in Word format: %IW-3x - starts at %IW1
NOTE: The State RAM address does start at address 0 for the discrete and analog Output modules. It is important to note that %IW and %MW are handled differently here. Since %M0 and %MW0 are not required to be assigned to I/O directly it is not covered by this effect. So for the discrete or analog Ouput modules, the starting input is set to 0.
