PNOZ mc10p sercos III
Overview
The data from the PNOZmulti is stored in a buffer. There is read/write access to the input
data (Byte 2048 to 2067); other data is read-only.
The object buffer is structured as follows:
Byte Content
0 - 19 Output data
79 - 127 I/O expansion modules, left
128 - 255 Diagnostic word (Low Byte)
256 - 383 Diagnostic word (High Byte)
384 - 511 Status of inputs
Status of input LED
Status of outputs
Status of LED
512 - 639 Configuration
640 - 767 Element types
2048 - 2067 Input data
2112 - 2117 Diagnostic data
Information
The first 20 input/output bytes are transferred cyclically by the PNOZmulti.
The rest of the data is updated piece by piece in each cycle. This may mean
that interdependent data is inconsistent. Updating all of the data can take up
to 500 ms
System requirements
Communication via sercos III is only possible with units from the stated version number on-
wards:
} PNOZ mc10p from Version 1
} Base units PNOZ mXp from Version 6.5
