FAQ

The FM 356-4 is configured using the "FM 356-4 Configuration Package" software, which integrates into the SIMATIC STEP 7 environment (classic, not TIA Portal).

Yes, the FM 356-4 is versatile and can control both stepper motor drives (with pulse/direction interface) and servo drives (with analog or pulse/direction interface), making it suitable for a wide range of applications.

No, the SIMATIC S7-300 FM 356-4 is part of the classic SIMATIC world and is programmed and configured using STEP 7 V5.x. For TIA Portal, you would need to use a technology module from the S7-1200 or S7-1500 series.
