Acyclic Communication using Record Data Sets

3.1.8 Acyclic Communication using Record Data Sets
In addition to cyclic data communication (PROFIBUS IO standard in
compliance with IEC 61158), PROFIBUS IO also offers acyclic
communication services as an option. These acyclic services run parallel to
cyclic data transfer. The data sets are addressed via the module slots, the sub-
module slots and the data set number (index) of the module. In doing so, the
sub-module slot should always be addressed with 1. The meaning of the
indexes can be determined in the area of 0x0000 to 0x7FFF according to the
manufacturer specifications. The area of 0x8000 to 0xFFFF is established by
the PROFINET IO standard and the following applications.

Data Set Detail diagnostics for PROFIsafe I/O Modules

Via channel diagnostics, the PROFIsafe I/O modules indicate if a fault has
occurred and if it has been caused by a module or channel failure. In the event
of a channel failure, the detail diagnostics is made available at "record data"
set 0x0024 (36) for the input channel and at "record data" set 0x002C (44) for
the output channel. Detailed module faults can be determined via "record
data" set 0x0034 (52). The length of the detail diagnostics that must be
requested is 2 bytes. The coding of the detail diagnostics is as follows:
Detail diagnostics "F Input channels PROFIsafe" (Data set 36, 2 Byte long)
Fault
0x0K01 Cross connection between two input channels that are supplied from two
0x0K27 Discrepancy fault with 2 channel evaluation. K contains the input channel
Detail diagnostics "F Output channels PROFIsafe" (Data set 44, 2 Byte long)
Fault
0x0K04 Overload to output channel K.
0x0K06 Wire break on output channel K.
0x0K23 Short circuit after 24 V of the output channel K.
0x0K24 Short circuit after 0 V of the output channel K.
Description
different clock signal sources. K contains the number of the input channel
that does not receive a clock signal because of the cross connection. If
there is a cross connection between two independent clock signal sources,
K is written to the input channel that had recognized the fault at first.
that has determined the discrepancy fault.
