Diagnostics
The PNOZmulti has many options for diagnostics and fault detection:
} LEDs on the base unit and expansion modules
} Diagnostic data via the communication interface and via a fieldbus
} Error stack
} Diagnostic word in the PNOZmulti Configurator
} Expanded diagnostic options using a visualisation system, e.g. PMImicro diag
Only for base units PNOZmulti Mini and PNOZmulti 2
} Display messages can be configured in the PNOZmulti Configurator
Detailed information on the diagnostic options are available in the document "PNOZmulti
communication interfaces".
LEDs on the base unit and expansion modules
The LEDs signal
} Operating states (e.g. "RUN")
} External and internal errors
The key to the LEDs can be found in the operating instructions supplied with the units.
RS232/Ethernet interface
The RS232/Ethernet interface on the configurable control system PNOZmulti is used to
transfer diagnostic data to an user program.
Diagnostic data
The diagnostic data can be called up via the RS232/Ethernet interface or via a connected
fieldbus. All base units that have an Ethernet interface also support Modbus/TCP.
The diagnostic data may only be used for non-safety purposes, e.g. visualisation.
The diagnostic data on PNOZmulti systems is:
} Version:
Product number, device version,
Serial number
} Status of inputs/outputs:
Indicates whether inputs and outputs are active or inactive (open/closed)
} LED status:
Indicates the status of the LEDs on the base unit and expansion modules (on/off/
flashes), plus the operating mode (start up, RUN, STOP)
} Simplified status scan:
Shows group messages relating to the safety system: Signal changes, LED status, op-
erating statuses
