FAQ

Question?

What size Micro Memory Card (MMC) is compatible with the CPU 316-2 DP (6ES7316-2AG00-0AB0)?

This CPU requires a Siemens Micro Memory Card (MMC) to operate. It supports MMC sizes up to 8 MB. It is crucial to use a genuine Siemens MMC, as standard SD cards are not compatible.

Can this CPU be programmed with TIA Portal, or does it require STEP 7 V5.x?

The SIMATIC S7-300 CPU 316-2 DP can be programmed using both classic SIMATIC STEP 7 V5.5 or later, and Siemens TIA Portal (e.g., V13, V14, V15). For TIA Portal, ensure you have the appropriate license and hardware support package installed.

What is the function of the mode selector switch (RUN-P/RUN/STOP)?

The switch controls the operating state of the CPU. 'STOP' halts program execution. 'RUN' executes the user program. 'RUN-P' allows for program changes while the CPU is running, though not all operations are permitted. The switch also has a position for Memory Reset (MRES).
