Pilz 773721 PNOZ Mc 3p PROFIBUS-DP Communication Module 24VDC Base Unit Expansion 9-pin Sub-D Female Connector

1. Overview of the Pilz 773721 PNOZ Mc 3p

The PNOZ mc3p (order number 773721) is a compact communication expansion card designed specifically for the PNOZmulti Classic system. The module connects directly to the PNOZmulti base unit via the backplane bus, upgrading the entire safety system to a Profibus-DP slave without additional wiring. Simply dial in the station address, and the 24 V power supply and 5 V logic supply are instantly ready. The DP port operates at up to 12 Mbit/s, auto-sensing, and safety I/O data is mapped to the PLC master in milliseconds, seamlessly integrating safety and standard control.

2. Core Features:

Fieldbus Integration: It functions as a PROFIBUS DP slave in the PNOZmulti Classic system and can communicate directly with any DP-V0/V1-compliant master (such as the Siemens S7-300/400/1200/1500), enabling transparent transmission of safety I/O data.
Virtual I/O Mapping: 128-bit virtual safety inputs and 128-bit virtual safety outputs are provided via the backplane bus and can be freely assigned in the PNOZmulti Configurator, eliminating the need for additional hardware wiring.
Online Diagnostics: Integrated LEDs (BF, RUN, ERR) provide real-time indication of bus faults, configuration errors, and communication status. Fault information can be read via a master or PG, facilitating remote maintenance.
Quick Startup: Station addresses 0–99 are set via top-mounted DIP switches, and baud rates from 9.6 kbit/s to 12 Mbit/s are automatically detected, ensuring plug-and-play operation.
