2.3 Operation of optris CT with the PROFIBUS-DP-V1 interface
After the GSD file (IT010A90.gsd) has been read into the configuration tool and transferred to the master, the
optris CT with PROFIBUS-DP-V1 interface is ready for data exchange. This can also be seen on the green
LED on the Profibus-DP-V1 interface, if the cover was removed from the optris CT (open only for testing
purposes).
2.4 Data conversion
The cyclic received data of the “object temperature” and the “internal sensing head temperature” are shown
in a 2 byte hex format. In this context the 1. byte is the high byte and the 2. byte is the low byte.
They are converted as following:
Hex format converts into decimal format, minus 1000 and divided by ten
Example:
0x04EB
→
1259
– 1000 / 10 = 25,9 °C
