17.2.4 Output Data Structure
The pyrometer module provides output data. The output data length of pyrometer module is 3 Byte.
The output data may be used to change the initialization of the device (which was set once at start-up)
when the bus is in data exchange mode.
To do so the following structure is defined:

Type of parameter

2 Byte
Integer (Big Endian, Motorola)
Parameter
The <Type of parameter> gives the meaning of the following parameters (with the same format as
described in section 17.2.2.2 Parameters of the Pyrometer Module, page 113):
Type of parameter
Meaning
0
ignore output data
1
emissivity
2
laser
3
background temperature (for background temperature compensation)
4
averaging time
5
peak hold time
6
valley hold time
7
set point for the relay
If <Type of parameter> is set to 0 then the output data gets ignored. So it should be set to 0 as default.
17.2.5 Diagnostics
The diagnostics information of the fieldbus communicator and the pyrometer modules can be read out
anti-cyclically using standard diagnostics data sets defined in the Profinet IO specification.
Errors occurring when configuring and setting the parameters of the fieldbus communicator and the
connected pyrometer modules as well as external errors are reported by the communicator via
channel specific diagnostic.
In productive data exchange between the I/O controller and the fieldbus communicator, one byte IOPS
process data qualifiers are available for each module providing information of the validity of the
pyrometer module data (good/ bad). In the event of an error occurs during operation, the problem-
