KS2000 Configuration software KS2000 Configuration software 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. 17: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline. - Page 32 KS2000 Configuration software 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.

Programming 5.1.2 Terminal configuration The terminal can be configured and parameterized via the internal register structure. Each terminal channel is mapped in the Bus Coupler. Depending on the type of the Bus Coupler and the mapping configuration (e.g. Motorola/Intel format, word alignment etc.) the terminal data are mapped in different ways to the Bus Coupler memory. -

Programming • R12: Minimum data length The particular byte contains the minimum data length for a channel that is to be transferred. If the MSB is set, the control and status byte is not necessarily required for the terminal function and is not transferred to the control, if the Bus Coupler is configured accordingly. -
