8.6.4.2. Pyrometer module output data
The output data length of Input/Output module is 5 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:
Address
Length
without offset
0 1 Byte
1 4 Byte
The <Type of parameter> gives the meaning of the following parameters (with the same
format as described in the section 8.6.3.1 for Pyrometer parameters)
Parameter type
0 Do not change anything
1 Slope
2 Emissivity
3 Transmissivity
4 Averaging time
5 Peak hold time
6 Valley hold time
7 Set point for the relay
8 Laser control
If <Type of parameter> is set to 0 then the output data gets ignored.
As default, it should be set to 0 (zero).

8.6.5. Diagnostics

The diagnostics information of the fieldbus communicator can be read out acyclically 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 Endurance®
PROFINET IO, 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-indicator in APDU-Status is set by the communicator
and a diagnostic alarm is additionally transmitted.
