4. Modifica & Machine Modernisation Projects

Perfect for legacy equipment upgrades:

Replace dozens of discrete safety relays with one controller, simplify wiring and reduce troubleshooting time.

Logic is software-configured; the built-in LCD directly pinpoints fault locations, cutting spare part varieties.

Program backup via SD card; replacement units run immediately after card insertion.

5. Selection Boundaries (When NOT to choose 772100)
6. Large production lines with high I/O count and demand for standard non-safety I/O → Choose PNOZ m B1 (772101)
7. Native EtherCAT FSoE bus required → Choose PNOZ m B2 (772102)
8. Minimal safety points with zero expansion needed → Compact PNOZ m C0 (772105)
9. Multi-burner furnace systems → PNOZ m B1 Burner
10. Bus Communication Solution: 772100 + 772138

Install the PNOZ m ES Profinet (772138) module on the left slot of PNOZ m B0:

Hardwired local safety cut-off remains fully independent. Safety status, fault codes and I/O states are uploaded to the main PLC via Profinet.

The PLC only performs monitoring; safety shutdown never relies on fieldbus communication, fully complying with functional safety regulations.
