Portfolio of the migration products
Early on Siemens recognized the significance of migration for
process automation, and for many years has offered a wide
range of innovative migration products and solutions for its glo-
bally proven systems. Right from the beginning, the maxim of
Siemens’ migration strategy is to modernize the existing in-
stalled basis in steps without completely changing the system;
and where possible without or with minimal plant downtime.
Siemens has the products to support customers’ endeavors to
achieve long-term safeguarding of investments together with
maximization of their return on assets, even for legacy systems
from other vendors.
Siemens’ know-how in the migration sector has continuously
grown as time has passed. The experience gained in numerous
migration projects has been incorporated into new products and
technologies which are even more efficient. For example, "Data-
base Automation" (DBA) is available for engineering of operation
and monitoring systems. Using DBA and a plug-in interface, it is
possible to download the configuration data, and to display and
configure them using a standardized user interface. DBA allows
system-based migration of operator system data from different
output systems in standardized form, thus providing uniform
software quality, security and understandability.
The migration products can be categorized as follows:
