Table 4-20   Compare’s Condition Type and Condition Time Prompts (continued) 

PULSE 

Used for interfacing with slower 
circuits. 
On rising edge of Result, 
creates pulse length 
CONDITION TIME and ignores 
additional rising edges of Result 
within that CONDITION TIME. 

Result switches ON(1) for 

≤

 

CONDITION TIME, then 
OFF(0). 

ON(1) for CONDITION TIME, 
then OFF(0).  During 
CONDITION TIME, any 
additional OFF(0)-to-ONs of 
Result are ignored.

RT PULSE 
(Re-triggerable pulse) 

Used for slower circuits. 

Result switches ON(1) for 

≤

 

CONDITION TIME, then 
OFF(0) 

ON(1) for CONDITION 
TIME, then OFF(0). 

 

Guarantees that CVn OS will be 
ON for CONDITION TIME after 
most recent rising edge of 
Result. 

Result switches ON(1) multiple 
times before CONDITION TIME 
expires 

ON(1) when Result first 
switches ON(1) and 
remains ON(1) until Result 
has not switched ON(1) for 
CONDITION TIME. 

 

 

Result switches ON(1) for 

≥

 

CONDITION TIME, then 
OFF(0) 

ON(1) for CONDITION 
TIME then OFF(0).
