THE PROCESS
An essential part of complex control,
weighing and dosing equipment is a PLC.
EME uses the latest generation PLC for
all process control tasks and calculations.
All weighing and dosing tasks are carried
out with the utmost precision, as the pro-
grammes reacts within 100 milliseconds.
Dosing speeds for raw materials are set
in the recipes and the PLC uses these
parameters to control the dosing equip-
ment. In the case of power controlled
dosing systems the dosing speed is ad-
justed automatically. Any deviations from
the set points in the dosing results are
detected and automatically corrected in
the subsequent charge of the same re-
cipe and the operator receives a warning
message. This significantly increases the
dosing accuracy for the constituents.
Individual dosing computers are no longer
required as weighing indicators can be in-
tegrated in the new high capacity PLCs.
This decreases the number of interfaces
and so reduces the fault potential and
programming costs.
