SIMATIC Software is continuously enhanced and improved. The Software Update Service (previously: software maintenance service) is the easiest way to regularly take advantage of these improvements. It ensures automatic delivery of all new software versions that are released after ordering the Software Update Service so that your software is always up to date.

The Software Update Service

• Saves time and effort:
  Once it is ordered, the Software Update Service is automatically renewed every year.
• Lowers costs:
  The service pays for itself after the first update as it costs less than an individually ordered update.
• Makes budgeting easier:
  Software expenditures can be accounted for early in the budgeting process and they are easier to write off.
