The Write Material Ready Flag command is used to signal to the PD3K+ that the upstream material management has
the appropriate component loaded at the inlet valve stack(s) of the pump(s) prior to a recipe change. This flag is
only used when multiple materials for a pump are fed to the PD3K+ via a single valve at the inlet valve stack (i.e. a
piggable system). See
for more info on Single inlet valve stacks.
NOTE:
NOTE:
NOTE: This flag should be cleared prior to or during a material change operation upstream of the inlet valve stack to
avoid having the wrong material being fed into the pump during a recipe change.
Example: Setting the Material Ready Flag for Pump 1.

The Read User ID command reads back the current User ID. See
, for more details on Job
Log and User ID. The User ID can be up to ten ASCII characters in length and is packaged as three little endian
segments of ASCII characters. No arguments are required.
Example: Read User ID that is currently “John Doe”.
