5.6.4 Tables
Further information can be requested in table form.
A table consists of one or more PNOZmulti 2 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 2
repeats the two numbers and sends the requested data.
There are a total of 11 tables, with the following contents:
Table 20: Process data, base unit
Table 21: Process data, right­hand expansion modules
Table 22 Process data, left­hand expansion modules
Table 23: Process data, fieldbus module / communication module
Table 70: Diagnostic words
Table 71: Enable elements
Table 80: Project information
Table 90: Device data, base unit
Table 91: Device data, right­hand expansion modules
Table 92 Device data, left­hand expansion modules
Table 93: Device data, fieldbus module / communication module
The content of the tables is described in detail in the Appendix [ 101] .
5.7 Requests
A request is defined via the request number and segment number.
The following requests are available:
Request
No. Segment
No.
Meaning
0x14 0x01 Send virtual inputs to the PNOZmulti 2
0x14 0x02 Send virtual inputs to the PNOZmulti 2, request state of the
virtual outputs and LED status from the PNOZmulti 2.
0x2C 0x02 Request state of virtual inputs and outputs from PNOZmulti 2
0x2F Request data from the PNOZmulti 2 in table form
0x5C Request all input and output data from the PNOZmulti 2
5.7.1 Mask (Mask Byte 0 ... Mask Byte 15)
The mask is used to determine which of the virtual inputs sent in a Byte are to be set. For
example, if only inputs i0 to i5 are to be set in Byte 8, 0x3F must be entered in the mask in
Byte 24.
