What will I find in my module?
Off-the-shelf products are shipped with a standard in-house-developed software.
The definition of standard, in this case, is “the environment which SECO adopts for validation”.
Anyway, custom in-house-developed software with different defaults can be built.
Contact your reference sales for further information.
