Honeywell VRX180 Manual De Usuario

Discrete Output function blocks control the relay or open collector output hardware.  The Program 
Discrete Outputs menu item will appear if a Discrete Outputs board is installed.  

 

If a discrete output has been assigned to a time proportioning output (DAT), it will not be programmable here.  
See "OUTPUT RELAY" in Table 4-13. 

 

Select a DO to program, then program the prompts in Table 4-15.  See Table 4-2 for additional prompts. 

ACTION STATE 

NORMAL, INVERT 

Determines whether the relay will normally be energized or 
de-energized when the DO’s Input is ON(1). To select 
energized when ON, enter NORMAL (not inverted). To select 
energized when OFF, enter INVERT (inverted). 

INPUT 

OFF, discrete parameter, 0, 
1 

Source of the Discrete Output. 

EVENT ENABLE 

NONE, RISING, FALLING, 
BOTH 

Determines whether changes in DO’s status can be recorded 
as events in data storage.  For storage to occur, Data 
Storage must also be programmed to store Events. 

NONE - status changes are not stored 

RISING - OFF(0)-to-ON(1) changes can be stored 

FALLING - ON(1)-to-OFF(0) changes can be stored 

BOTH - Rising and falling changes can be stored
