Overview of
application
Supplier : Avantec,
Norway
The system supplied performs corrosion tests on
different Hastelloy materials. In order to do this 5 different sequences
have been implemented in software to run the tests on the materials, these
are automatic and under PC control, but manual sequences are also
undertaken.
Altogether the software handles 12 PID
controller loops and 8 sequences facilitated by the multitasking nature of
the DM2-386 package.
All the valves in the process are controlled
using two digital inputs which give the status at any one time in order to
achieve the necessary level of safety.
Temperature
sensors and 4-20 mA sensors such as Flow meters, PH meters and level
meters are mixed and matched on the same Datascan input modules, reducing
the space needed for the hardware, the wiring and therefore the overall
cost.
Datascan was used instead of Programmable Logic
Controllers for its 16 bit resolution on Analog Inputs, and the ease of
configuration.
