FAQ

Question?

Can I program this S5-95U CPU with modern TIA Portal software?

No, the SIMATIC S5 series requires legacy programming software like STEP 5. It is not compatible with the modern TIA Portal platform, which is designed for the S7-1200, S7-1500, S7-300, and S7-400 series.

What is the function of the battery, and how do I know if it needs replacement?

The 3.6V lithium battery is crucial for retaining the user program in RAM when the PLC is powered off. The 'BATTERY OFF/LOW' LED on the front panel will illuminate to indicate a low or failed battery, signaling that it needs to be replaced to prevent program loss.

What communication interfaces does the 6ES5095-8MA03 have?

This CPU has a built-in PG (Programming Device) interface, which is a proprietary serial interface (TTY/20mA current loop) used for programming and diagnostics with a Siemens programmer or a PC running STEP 5 software.
