🔍 Spare Parts & Ersatzinformationen
Originaler direkter Ersatz: Same part number 772138. Check the latest PILZ product obsolescence notice for end-of-life status.
Domestic equivalent reference: Innovation, Xinje safety PLC, Schneider XPSM series. These are solution-level alternatives only, not direct hardware drop-in replacements. Safety logic must be reconfigured.
📎 Common Troubleshooting Checklist
- No LEDs after power-up: Check DC24V supply and polarity
- Flashing fault LED: Configuration validation error, wiring short-circuit, OSSD overload
- Safety circuit cannot be enabled: Check wiring of safety input channels, contact status of E-stop / Sicherheitstor, software configuration logic
- Kommunikationsfehler: Inspect network cable, IP-Adresse, software version compatibility
PNOZmulti Configurator Getting Started Example (PNOZ m B0 /772138)
Project Goal: Dual-channel E-stop + dual-channel safety gate, shared external reset button, meeting PL e / SIL3. Uses only onboard I/O of the base unit, no expansion modules.
Software: PNOZmulti Konfigurator (free download from official website, graphical drag-and-drop configuration, no coding)
- Hardware Point Assignment (PNOZ m B0 Terminal Block)
| Signal | Hardware Channel | Beschreibung |
| Dual-channel E-stop (normalerweise geschlossen) | I0 / I1, test pulses T0 / T1 | Typ 3 Zweikanalig, cross-contact short-circuit detection |
| Dual-channel safety gate (PSEN mechanical safety gate, normalerweise geschlossen) | I2 / I3, test pulses T2 / T3 | Typ 3 Zweikanalig, cross-contact short-circuit detection |
| Manual reset button (normalerweise offen) | I4 | Reset signal, single-channel input |
| Safety semiconductor OSSD output | O0, O1 (paired OSSD) | Safety enable output, treibt Servo an / contactor safety circuit |
Wiring Note: E-stop and safety gate must use two independent normally closed contacts. The reset button is normally open. Manual reset is mandatory (per safety standards: manual confirmation required after fault clearance; automatic restart on power-up is prohibited).

- Open Configurator → New project, hardware selection PNOZ m B0 (772138)
- Eingeben [Hardwarekonfiguration]: No expansion modules for this project, confirm directly
- Eingeben [User Program] (graphical canvas, drag-and-drop function blocks)
III. Hinzufügen & Configure Function Blocks
1) Add E-STOP Function Block
Drag E-STOP from the library onto the canvas
Input tab:
Schaltertyp: Type3 (Dual-channel NC)
✅ Check Detect short-circuit between contacts (mandatory for dual-channel fault diagnosis)
Kanal1: I0, test pulse T0; Kanal2: I1, test pulse T1
Reset tab: Manueller Reset, reset input I4
Name: E-STOP_Machine_EmergencyStop
2) Add Safety Gate Function Block
Drag the Safety Gate function block
Input tab:
Typ: Type3 dual-channel normally closed
✅ Check detect short-circuit between contacts
Kanal1: I2, T2; Kanal2: I3, T3
Reset tab: Manueller Reset, reset input I4 (shared reset button with E-stop)
Name: `SAFETY_GATE_ProtectionGate`
3) Add AND Logic Block
Logic rule: E-stop OK AND Safety gate closed → Safety output enable
Drag AND logic block
Two AND inputs: connect to OK output of E-STOP block and OK output of Safety Gate block respectively
AND output → connect to [Semiconductor Safety Output OSSD] function block
4) Add Semiconductor Safety Output OSSD
Drag OSSD output block, assign hardware O0, O1 (paired safety output)
Eingang: Output signal from AND block
Output feedback: Contactor feedback monitoring not implemented in this example; can be added later if required
Simplified logic description: E-stop released AND safety gate closed → press reset, OSSD safety output ON. If any safety condition is violated, OSSD cuts off immediately.
- Validierung, Herunterladen & Online Diagnostics
- Klicken [Project Validation] to check CRC, parameters and hardware matching, resolve all errors
- Two download options:
Option A: Micro USB cable directly connected to PNOZ m B0 for online program download
Option B: Download to memory chip card, insert card into controller; program loads automatically on power-up
- Online diagnostic: Real-time monitoring of I0~I4 input status, OSSD output status and fault codes
- Nach dem Download, set hardware to Run mode and perform field testing
- Field Test Logic (Überprüfung)
- Normal condition: E-stop released, safety gate closed → press reset → OSSD output ON (safety enable)
- E-stop pressed: E-STOP block trips → AND output de-energized → OSSD OFF immediately
- Safety gate opened: Safety gate block trips → AND output de-energized → OSSD OFF immediately
- Fault recovery: After E-stop released / gate closed, reset button must be pressed again to re-enable safety output
- Common Configuration Pitfalls (Hohe Priorität)
- Type3 dual-channel: Two contacts must be independent, do not short internally, otherwise short-circuit detection triggers faults
- Test pulse T must correspond one-to-one with input I; channels cannot share test pulses
- Reset configuration: Machinery safety standards forbid automatic reset. Safety output cannot auto-restart after gate opening or E-stop activation
- OSSD is semiconductor output with short-circuit monitoring; short circuit on downstream load triggers safety fault
- Sicherheitsbewertung: This configuration achieves PL e / SIL3 only with correct wiring. Incorrect wiring downgrades safety level.
VII. Erweiterungsoptionen (Modify within the same project later)
Add safety light curtain function block
Add contactor feedback monitoring (external feedback circuit)
Add OFF-Delay for inertial stopping

✅ Application Selection Guide (When to choose PNOZmulti2)
Recommended when:
Safety logic is not simple series connection of E-stop + Sicherheitstor, requiring AND/OR logic, Timer, zone safety, conditional interlocks
High quantity of safety I/O, many safety gates, light curtains and E-stops to be centrally managed
Safety motion monitoring required (SLS/SSM/SS1 etc.)
Fieldbus communication needed (Profinet, EtherCAT) to upload safety diagnostics to standard PLC (772138 Profinet module widely adopted)
Frequent product changeovers requiring safety logic modification without hardware swap
Inter-safety communication between multiple machines (Multi Link module for safe data exchange between two PNOZmulti2 controllers)
Not recommended (simple applications, discrete safety relays offer lower cost):
Nur 1 dual-channel E-stop, no other safety signals, einfache Logik
No fieldbus, no motion monitoring, minimal safety I/O
📌 Typical Configuration Example (772138 Lösung)
PNOZ m B0 (772100) + PNOZ m ES Profinet (772138) + EF I/O expansion modules
Anwendung: Robot workstation / Bearbeitungszentrum. Safety logic runs independently inside PNOZmulti2. Profinet transmits safety status and fault codes to Siemens S7 PLC / HMI.
🔎 Core Strengths Matching Application Highlights
- Graphical drag-and-drop configuration, simple safety logic modification
- Modular architecture: Basiseinheit + I/O-Erweiterung + Bus + motion modules assembled on demand
- Independent safety kernel: Safety logic runs autonomously, independent of upper PLC (core advantage of safety controllers. Protection remains valid even if main PLC fails.)
- Supports IP67 distributed remote I/O for large production lines
- Multi-axis safety motion monitoring, key selling point for machine tool and robot applications
- Rich fieldbus interfaces for seamless connection with mainstream PLC brands
