Ordering

The different variants have their own specific order numbers that identify the type
designation for the desired hardware and software combination.
The type code designation can be seen in Fig. 7.-1:
Fig. 7.-1 Type code designation for ordering REF 542plus
Each code is dedicated to a specific application or module. The description for each
type code is listed in the following tables. The codes mentioned below are mostly
used for the operations field of REF 542plus. The codes are slightly different in
DNV and ATEX. Because ATEX certification is only valid for a specific version of
REF 542plus, it is required to obtain a new certification after each release. The
release 1.1 of ATEX certified units is REF 542plus with version V4C02, release 2.0
with version V4D02 and release 2.5 with version V4E04. For releases 1.1 and 2.0
the REF 542plus unit is delivered with the previous HMI V4 and for release 2.5
with the new HMI V5. Order the DNV certifies for marine application. Note that the
DNV version can only deliver with the previous HMI V4.
