Emerson DL8000 - Prompt Additives (0 X03)

DL8000 Preset Instruction Manual
Revised February-2016 Communications Protocols D-17
Prompt Additives
[0x03]
Allows the TAS to let an operator select additives at the keypad. The
command locks out the keypad and display to the TAS.
The DL8000 displays an additive selection screen with the suggested additive
selection [63,0,170]. The suggested additive selection can also be “no
additives.” The operator has to select an additive within the timeout time
[63,0,171]; otherwise the operation aborts and sets the Operation Timed Out
flag (bit 3 in [63,0,119]). If a timeout occurs, it blocks any further additive
selection.
If you set the timeout to zero, then the timeout doesn’t occur. You must then
use the Timeout Operation command (0x5) to end this operation.
This command does not result in an additive selection being set in the
DL8000. It just allows the TAS to obtain a possible additive selection from an
operator at the DL8000. The TAS can change the additive selection by writing
its own value at [63,0,60] (using Modbus write function code), but only when
the transaction is not authorized and the Operation Timed Out flag is not set.

Results
When an operator selects an additive, the DL8000
sets the Additive Selected flag (bit 5 in [63,0,119])
to tell the TAS that it can read the selected
additive. The TAS can read additive selected
bitmap [63,0,112] using Modbus read function
code.
