Page 13: Basic Function Principles
Product overview Basic function principles The high-precision KL3172 analog input terminals can measure two voltages (KL3132, KL3162, KL3172, KL3182) or two currents (KL3142, KL3152) and display them with a resolution of 16 bits (65535 steps). High- precision measurements are ensured through cyclic self-calibration. By default, the inputs are switched as differential inputs. - Page 14 Product overview Name Name Unit Register Output value of the A/D converter Process data for controller Vendor calibration: Offset (can be disabled via bit R32.5 [} 49] of the R17 [} 47] feature register) Vendor calibration: Gain (always active) [1 x 2 + 1] R18 [} 47] Calibration: Offset (can be enabled via bit R32.5 [} 49] of the feature R1 [} 46]...
- Page 15 Product overview • In the first phase of the calibration, an input voltage of 0 V is applied to both analog inputs (zero calibration). The zero points of both analog input stages can be determined in this way. For this measurement, the respective absolute value of the channels is of interest. The value is subsequently stored in the RAM (register R1 [} 46]).

Configuration Software KS2000 Configuration Software KS2000 KS2000 - Introduction The KS2000 configuration software permits configuration, commissioning and parameterization of bus couplers, of the affiliated bus terminals and of Fieldbus Box Modules. The connection between bus coupler / Fieldbus Box Module and the PC is established by means of the serial configuration cable or the fieldbus. Fig. 15: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline. - Page 30 Configuration Software KS2000 Commissioning The KS2000 software facilitates commissioning of machine components or their fieldbus stations: Configured settings can be transferred to the fieldbus modules by means of a download. After a login to the terminal station, it is possible to define settings in couplers, terminals and Fieldbus Box modules directly online. The same high-level dialogs and register access are available for this purpose as in the configuration phase.
