• Data Exchange: M0/M1 files (SLC ↔ PROFIBUS), up to 1536 bytes cyclic input / 1536 bytes cyclic output.

2. Key Features

• Single PROFIBUS DP‑V1 master port (DB9, RS‑485)

• Full DP‑V1 support (acyclic services, alarm handling, data exchange)

• DP‑V0 backward compatible (works with legacy DP slaves)

• Max slaves: 125 (with repeaters)

• Cyclic data: 1536 bytes IN / 1536 bytes OUT

• Acyclic messaging: Parameterization, diagnostics, read/write

• Dedicated processor: No SLC CPU load impact

• Configuration: ProSoft Configuration Builder (PCB) softwareProSoft Technology Inc

• Diagnostic LEDs: PWR, RUN, BP LINK, DP LINK, DP ACT

• Battery‑backed RTC & CMOS (21‑day backup, non‑replaceable battery)ProSoft Technology Inc
