MultiSmart Installation & Operation Manual

24 PLC Extension IEC 61131-3 (ISaGRAF)

ISaGRAF, a control software environment which supports all of the internationally recognised IEC 61131-3
control languages and offering a combination of highly portable and robust control engine, is available in
MultiSmart. MultiSmart currently only supports ISaGRAF version 5. Earlier versions of ISaGRAF are not
supported.
This new development of MultiSmart allows system integrators and end-users to further enhance or adapt
the capability of MultiSmart. The existing functionality set in the product is very high, but there are always
customers or applications that push the envelope. The product has 1000s of tags, and system integrators or
end-users can now interface to these with the PLC engine. This means they can extend the capability
without having to rewrite existing functions.
The ISaGRAF implementation of IEC 61131-3 is added because it is the most proven platform and version 5
is chosen as it offers a number of advantages over version 3. One example is the ability in v5 to run different
'resources', or applications, at different rates to allow more critical applications to run more frequently.
NOTE:
This is an optional feature that must be purchased with the MultiSmart, or enabled later on the
MultiSmart before it can be used. To check if this feature is enabled refer to Section 28.
ISaGRAF 5 (and patches if any, which are needed for the ISaGRAF logic development), can be downloaded
from www.isagraf.com. The MultiSmart definition file required for the ISaGRAF programming can be
downloaded from
www.multitrode.com. The logic, after building, should be downloaded into the MultiSmart for ISaGRAF to
run.
