Mounting and wiring • The High Density Terminals (HD Terminals) include electronics and connection level in a single enclosure and have advanced packaging density. Standard wiring (ELxxxx / KLxxxx) Fig. 9: Standard wiring The terminals of ELxxxx and KLxxxx series have been tried and tested for years. They feature integrated screwless spring force technology for fast and simple assembly. -
Page 19: Wiring
Mounting and wiring The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal point without tools. -

Page 27: Configuration Software Ks2000
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. 16: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline. - Page 28 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.

Page 29: Access From The User Program
Access from the user program Access from the user program Terminal configuration The terminal can be configured and parameterized via the internal register structure. Each terminal channel is mapped in the Bus Coupler. Mapping of the terminal data in the Bus Coupler memory may differ, depending on the Bus Coupler type and the set mapping configuration (e.g. Motorola/Intel format, word alignment etc.). -
Page 30: Mapping In The Bus Coupler
Access from the user program • KL3041 and KL3051: 2 bytes of input data • KL3042 and KL3052: 4 bytes of input data • KL3044 and KL3054: 8 bytes of input data Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000 configuration software is required. -
