Frequently Asked Questions

• Can I use this CPU with TIA Portal?

  Yes, it is fully supported in TIA Portal V13 and later.

• What is the maximum number of DP slaves on the 2nd interface?

  Up to 96 slaves with a total address area of 6 KB each for inputs and outputs.

• Does it support isochronous mode?

  Yes, with a shortest clock pulse of 5 ms (or 2.5 ms without SFC 126/127).

• Is the working memory expandable?

  No, it is fixed at 768 KB, but load memory is expandable via FEPROM/RAM cards.

• What battery type does it use?

  Standard backup battery with typical current draw of 40 µA.

• Can I run multiple CPUs in one rack?

  Yes, up to 4 CPUs in UR1 or UR2 racks (multicomputing).

• How do I update the firmware?

  Firmware updates are done via STEP 7 using the memory card or online function.

Selection Guide

• Choose this CPU if: you need 768 KB working memory, 3 onboard interfaces, and support for up to 128 DP slaves.
• Compare with 414-2: The 414-3 adds a 3rd IF slot and larger address area (6 KB per interface).
• For larger applications: consider 416 or 417 CPUs with more memory and I/O capacity.
• Memory card recommendation: FEPROM for permanent storage, RAM for temporary expansion.
