Inputs
The ProMix PD3K+ Network Inputs are Write-Read capable, but should be treated as outputs from a PLC or other
networking device. These registers allow the user to control system operation and configure system settings remotely.
Invalid values (i.e. out of bounds or not consistent with system configuration) will be ignored by the ProMix PD3K+.
All values must be written as integers. Floating point numbers are not supported.
Do not rely on these registers for Read status, other than to confirm data that has been written and accepted.
NOTE:
NOTE:
NOTE: The PD3K+ system does not refresh the values for these registers. At power up all input registers initialize
to invalid values.

Alarm/Deviation
The Clear Active Alarm register is used to
acknowledge an alarm remotely so that the system
may resume operation. Be sure that the alarm
condition has been alleviated. Write a 1 to this
register to acknowledge the latest active alarm. If
more than one alarm is currently active only the most
recent alarm will be acknowledged. A repeated write
should be performed to clear any remaining active
alarms. See figure 9.
(See
for more information
on clearing alarms.)
NOTE:
NOTE:
NOTE: This register is not polled by the ProMix
PD3K+. An alarm is cleared only when a value of ‘1’
is written to this register. It is recommended that the
automation reset this register by writing a 0 to it at all
other times to avoid inadvertently clearing an alarm.*

The Go to Recipe Number register is used as a
queue for the next recipe to be loaded when a recipe
change is initiated. A number between 0 and 40 can
be written to this register. However, a recipe must be
enabled via the ADM before it can be loaded. See

NOTE: Writing to this register does not trigger a recipe
