Error code
The data must be processed (copied) into especially created tags in a correct format in accordance to column
“Format”. For example, to obtain the internal temperature of the device, one should create a REAL tag and an
instruction copying 4 bytes of the device’s input data into this tag, beginning with byte 12.
9.4 Output Data
Once the pyrometer has been initialized and is running in the data exchange mode, only the below listed
parameters can be changed, using the device’s output data.

UDINT
To send the parameters and their values to the device, they must be stored in the controller tags first and then
copied to their destination register in the device. Please note, that most of the values of the parameters are REALs
whereas the parameter for laser control uses UDINT format – at least this value must be stored in a separate tag.
9.5 Diagnostics
The EtherNet/IP device has a designated status register. The bits of this register make up for an error code, which
is sent as a part of input data.
