Logic Command Word
Comparison
Table 40 shows the line side converter communication Logic Command Word
comparison that applies to the Logix Add-On-Profile (AOP). The Logic
Command Word functions are predefined by the AOP and associated tags are
automatically assigned in the Logix project.
• “Start” is a momentary command, that is, a transition from ‘0’ to ‘1’
performs the start function. A ‘1’ to ‘0’ transition of the “Start”
command has no effect on operation and does NOT perform a stop
function.
• The “Run” command is a maintained function. A ‘0’ to ‘1’ transition of
the “Run” command performs the run function. A ‘1’ to ‘0’ transition of
the “Run” command performs a stop function.
• The “Stop” command must transition from ‘0’ to ‘1’ to perform a stop
function. The “Start” and “Run” commands are inhibited if the “Stop”
command is ‘1’. The “Start” or “Run” commands must transition from
‘0’ to ‘1’ after a stop command in order to perform the start or run
functions.

communication. For example x:7 [Dig Out Setpoint]
can be assigned to an Output Datalink, where x = slot/
