8.3.4. Structure of the input/output data
8.3.4.1. Pyrometer module input data
The input data length is 23 Byte.
Address
without offset
Length Format Value
0 4 Byte REAL (Big Endian, Motorola) Target Temperature 2 color
4 4 Byte REAL (Big Endian, Motorola) Target Temperature 1 color wide
8 4 Byte REAL (Big Endian, Motorola) Target Temperature 1 color narrow
12 4 Byte REAL (Big Endian, Motorola) Internal temperature
16 4 Byte DWORD Error Code
20 1 Byte BYTE Bit0 (Bool) Trigger state ( 0
– reset, 1 – set)
21 2 Byte INT(Big Endian, Motorola) Measured attenuation
8.3.4.2. 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
without offset
Length Format Value
0 1 Byte BYTE Type of parameter
1 4 Byte REAL/ WORD
(Big Endian, Motorola) Parameter
The <Type of parameter> gives the meaning of the following parameters (with the same format
as described in the section 8.3.3.1 for Pyrometer parameters)
Parameter type Meaning Format
0 Do not change anything
1 Slope REAL
2 Emissivity REAL
3 Transmissivity REAL
4 Averaging time REAL
5 Peak hold time REAL
6 Valley hold time REAL
7 Set point for the relay REAL
8 Laser control WORD
If <Type of parameter> is set to 0 then the output data gets ignored.
As default, it should be set to 0 (zero).
8.3.5. Diagnostics
The diagnostics information of the fieldbus communicator can be read out acyclically using
standard diagnostics data sets defined in the PROFINET IO specification.
