Product Dimensions：

Siemens wants to keep your control systems stable. If you’re on the fence about when to 

upgrade your APACS+ process control system or QUADLOG safety controller during the 

next 10 years, its ok, Siemens offers a program to maintain your plant until you decide.

The typical life expectancy of distributed control systems is 20-25 years. APACS+ was 

introduced in 1992 and is now 20 years old. We are supporting you through 2020 with 

parts and components to keep your plant up and running until then . . . and beyond.

When maintaining a system like APACS+ for years to come, you may want to 

consider the following areas in order to optimize and improve your plant’s process:

n System performance

n System capacity

n Key system components

Siemens offers products that can help you during this critical time.

Increase your system performance:

n Improve the performance of your M-NET network by upgrading to Ethernet, using an 

Industrial Ethernet Module (IEM).

n Improve the performance of your APACS+ controller, especially if you’ve changed the 

configuration in the last 20 years, with an upgraded CPU allowing for a faster scan 

rate, using an ACMx Module (or CCMx for your QUADLOG safety system). 

Increase your system capacity:

n If you’ve increased the size of your configuration in the last 20 years, you may want to 

think about more memory. Not only does the new ACMx module have more memory 

than previous versions, the overhead code needs less of it, thereby freeing up the 

extra memory for your configuration. The extra memory can be used to support your 

larger configuration or expanded I/O capacity.

n Before deciding on a migration path forward, you may need to expand your plant. New 

APACS+ or QUADLOG I/O modules are available for the new process area in your plant. 

These modules are compatible and can be integrated with a SIMATIC PCS 7 system so 

the investment can be used well into the future.

n When adding a new area to the plant, you may require more than just I/O modules. 

Whole integrated APACS+ controllers (Racks, ACMx, Power Supplies and I/O) are also 

available. These can help you automate the remaining process area for years to come 

before you decide to migrate.

We have the same series of models in stock.  If you don't find the model you need, please contact us and we will provide you with an official quotation！
