🧩 Product Positioning

The PNOZ m B0 (772138) is a compact modular safety PLC within the PNOZmulti family. It operates independently. When I/O capacity is insufficient, PNOZmulti expansion modules (per esempio. 772140, 772142) can be added to expand safety inputs and relay outputs.

🛠️ Scenari applicativi tipici

Macchine utensili, macchine per l'imballaggio, linee di produzione automatizzate

Robot safety protection, safety gate interlocking

Emergency stop circuits, safety light curtain monitoring

Presse, conveyor safety control

⚠️ Critical Model Distinction (Confusione comune)

772138: PNOZ m B0 (semiconductor OSSD outputs, 4 OSSD channels)

772140: PNOZ m B1 (version with relay outputs)

📌 Configuration & Diagnostica

PC Connection: Use USB/Ethernet to connect to a PC for program download and online diagnostics via PNOZmulti Configurator

Local Indication: Front-panel LEDs for fast diagnosis of input, output and fault status

🔍 Spare Parts & Informazioni sulla sostituzione

Sostituzione diretta originale: Same part number 772138. Check the latest PILZ product obsolescence notice for end-of-life status.

Domestic equivalent reference: Innovazione, 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

1. No LEDs after power-up: Check DC24V supply and polarity
2. Flashing fault LED: Configuration validation error, wiring short-circuit, OSSD overload
3. Safety circuit cannot be enabled: Check wiring of safety input channels, contact status of E-stop / cancello di sicurezza, software configuration logic
4. Errore di comunicazione: Inspect network cable, IP address, 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 Configurator (free download from official website, graphical drag-and-drop configuration, no coding)

1. Hardware Point Assignment (PNOZ m B0 Terminal Block)

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).

1. New Project Setup in Software
2. Open Configurator → New project, hardware selection PNOZ m B0 (772138)
3. Entra [Configurazione hardware]: No expansion modules for this project, confirm directly
4. Entra [User Program] (graphical canvas, drag-and-drop function blocks)

III. Aggiungere & Configure Function Blocks

1) Add E-STOP Function Block

Drag E-STOP from the library onto the canvas

Input tab:

Tipo di interruttore: Type3 (Dual-channel NC)

✅ Check Detect short-circuit between contacts (mandatory for dual-channel fault diagnosis)

Channel1: I0, test pulse T0; Channel2: I1, test pulse T1

Reset tab: Ripristino manuale, reset input I4

Nome: E-STOP_Machine_EmergencyStop

2) Add Safety Gate Function Block

Drag the Safety Gate function block

Input tab:

Tipo: Type3 dual-channel normally closed

✅ Check detect short-circuit between contacts

Channel1: I2, T2; Channel2: I3, T3

Reset tab: Ripristino manuale, reset input I4 (shared reset button with E-stop)

Nome: `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)

Ingresso: 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.

1. Validation, Scaricamento & Online Diagnostics
2. Click [Project Validation] to check CRC, parameters and hardware matching, resolve all errors
3. Two download options:

Opzione A: Micro USB cable directly connected to PNOZ m B0 for online program download

Opzione B: Download to memory chip card, insert card into controller; program loads automatically on power-up

3. Online diagnostic: Real-time monitoring of I0~I4 input status, OSSD output status and fault codes
4. After download, set hardware to Run mode and perform field testing
5. Field Test Logic (Verifica)
6. Normal condition: Pulsante di emergenza rilasciato, safety gate closed → press reset → OSSD output ON (safety enable)
7. E-stop pressed: E-STOP block trips → AND output de-energized → OSSD OFF immediately
8. Safety gate opened: Safety gate block trips → AND output de-energized → OSSD OFF immediately
9. Fault recovery: After E-stop released / gate closed, reset button must be pressed again to re-enable safety output
10. Common Configuration Pitfalls (High Priority)
11. Type3 dual-channel: Two contacts must be independent, do not short internally, otherwise short-circuit detection triggers faults
12. Test pulse T must correspond one-to-one with input I; channels cannot share test pulses
13. Reset configuration: Machinery safety standards forbid automatic reset. Safety output cannot auto-restart after gate opening or E-stop activation
14. OSSD is semiconductor output with short-circuit monitoring; short circuit on downstream load triggers safety fault
15. Valutazione di sicurezza: This configuration achieves PL e / SIL3 only with correct wiring. Incorrect wiring downgrades safety level.

VII. Opzioni di espansione (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

Add Modbus TCP/Profinet communication to transmit safety status to PLC

✅ Application Selection Guide (When to choose PNOZmulti2)

Recommended when:

Safety logic is not simple series connection of E-stop + cancello di sicurezza, 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):

Soltanto 1 dual-channel E-stop, no other safety signals, logica semplice

No fieldbus, no motion monitoring, minimal safety I/O

📌 Typical Configuration Example (772138 Soluzione)

PNOZ m B0 (772100) + PNOZ m ES Profinet (772138) + EF I/O expansion modules

Applicazione: Robot workstation / machining center. Safety logic runs independently inside PNOZmulti2. Profinet transmits safety status and fault codes to Siemens S7 PLC / HMI.

🔎 Core Strengths Matching Application Highlights

1. Graphical drag-and-drop configuration, simple safety logic modification
2. Modular architecture: Unità base + Espansione I/O + bus + motion modules assembled on demand
3. Independent safety kernel: Safety logic runs autonomously, independent of upper PLC (core advantage of safety controllers. Protection remains valid even if main PLC fails.)
4. Supports IP67 distributed remote I/O for large production lines
5. Multi-axis safety motion monitoring, key selling point for machine tool and robot applications
6. Rich fieldbus interfaces for seamless connection with mainstream PLC brands
