4.11 Program Discrete Outputs
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.
ATTENTION
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.
Prompt
ACTION STATE
NORMAL, INVERT
INPUT
OFF, discrete parameter, 0,

Programming Function Blocks and Features
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).
Source of the Discrete Output.
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
