4.9 Calibration
The concept "calibration", which has historical roots at Beckhoff, is used here even if it has nothing to do with
the deviation statements of a calibration certificate.
• Vendor calibration, index 0x80n0:0B
The vendor calibration is enabled via index 0x80n0:0B. The parameterization takes place via the
indices:
◦ 0x80nF:01 vendor calibration: Offset
◦ 0x80nF:02 vendor calibration: Gain
• User calibration, index 0x80n0:0A
The user calibration is enabled via index 0x80n0:0A. The parameterization takes place via the indices:
◦ 0x80n0:17 User calibration: Offset
◦ 0x80n0:18 User calibration: Gain
• User scaling, index 0x80n0:01
The user scaling is enabled via index 0x80n0:01. The parameterization takes place via the indices:
◦ 0x80n0:11 User scaling: Offset
◦ 0x80n0:12 User scaling: Gain
Vendor calibration
The vendor reserves the right to carry out the basic calibration of the terminal/box modules. There-
fore, the vendor calibration cannot be changed.
