Remote DH+ Addressing
Blender Total Rate — F9:90 — Read Only — total rate that all the augers are running at,
this is not the extrusion rate
Extrusion Rate — F25:1 — Read Only — the rate at which the extruder is taking away the
blended material
Stable Extrusion Flag — B3:3/1 — Read Only — this flag is set once the blender
accurately learns the extrusion rate. This flag should be read before using the
“Extrusion Rate” data described above, if this flag is set to “0” then the OEM should use
previous relationships for extrusion rate per RPM. This relationship can be developed
using the “Stable Extrusion Flag”, “Extrusion Rate”, and the current extruder RPM. Once
this relationship has been developed it should be stored by the OEM.
Extruder RPM — F9:29 — Read Only — available only if “Extruder RPM Voltage
Reference” is enabled (the customer supplies the blender with a 0-10 Volt/4-20 mA signal
that references drive speed, usually this can be taken from the drive itself and is
recommended if the customer plans to use the “Extrusion Rate” information for extrusion
control calculations.
Extruder RPM Voltage Reference — N11:0/1 — Read/Write — Maintained — when set to 1
this instructs the blender to use a 0-10V/4-20 mA signal to calculate extruder RPM. This
is then used by the blender to develop and buffer the relationship between extrusion rate
and extruder RPM. This should always be used when the customer is planning on using
the “Extrusion Rate” information for extrusion control calculations.
Maximum Extruder RPM — F9:180 — Read/Write — only used if the “Extruder RPM
Voltage Reference” is enabled, use this to adjust the displayed “Extruder RPM” value of
the blender. If the displayed RPM is too low then increase this value, if it’s too high then
decrease this value.
User Password — N11:35 — Read/Write — only used when the operator is accessing the
“Calibration/Diagnostics” page from the Panel View. If set to “0” then no password will
be necessary for the operator to calibrate the blender from the Panel View.
Handling the blender recipe — the current blender recipe that is running in the blender
can be read without any special procedure. In order for the OEM to properly change the
recipe remotely they will need to complete a procedure in the proper order and examine
certain addresses to ensure that the recipe that the operator enters is accepted. This
procedure is already handled at the Panel View, but if you wish for the operators to be
able to enter in the blender recipes at the OEM screen then this procedure must be
followed.
