FAQs

What is this module used for?

It's the main processor (CPU) for the Siemens S5-155H controller. It runs your automation program to control machines and processes.

How do I connect my programming laptop to it?

Use the built-in 20 mA TTY port (15-pin socket). You will need a matching cable to connect to your PG/PC for setup and monitoring.

Is 1664 KB of memory enough for my project?

For most S5 programs, it is very large. You can store a very extensive logic program and data. If needed, add the Flash EPROM submodule for even more space.

Can I use this to upgrade my old S5 system?

Yes, it is a direct replacement CPU for the S5-155H rack. Always check your rack model and backup your program first.

What happens if the power goes out?

The program in RAM needs a battery backup. For permanent storage without power, use the Flash EPROM memory submodule to save your program safely.
