LED status
The status of the LEDs is stored in a byte as follows:
} Bit 0 = 1: LED OFAULT is lit or flashes
} Bit 1 = 1: LED IFAULT is lit or flashes
} Bit 2 = 1: LED FAULT is lit or flashes
} Bit 3 = 1: LED DIAG is lit or flashes
} Bit 4 = 1: LED RUN is lit
} Bit 5-7: Reserved
Tables
Further information can be requested in table form.
A table consists of one or more segments. Each segment is made up of 13 Bytes.
The communications partner requests the required data using the table number and seg-
ment number. The PNOZmulti repeats the two numbers and sends the requested data.
There are a total of 10 tables, with the following contents:
Table 1: Configuration
Table 2: Reserved
Table 3: State of inputs
Table 4: State of outputs
Table 5: Status of LED
Table 6: Reserved
Table 7: Diagnostic word
Table 8: Element types
Table 9: Transfer/state of the expanded virtual inputs and outputs
Table 10 State of the virtual inputs and outputs on the integrated link inter-
face on the PNOZ mm0.2p
Table 11 State of the safe inputs and outputs on the safe Ethernet connec-
tion
Element types The element type's byte is entered in Table 8
The content of the tables is described in detail in the Appendix.
Requests
A request is defined via the request number and segment number.
