Mounting and wiring Assembly Fig. 4: Attaching on mounting rail The Bus Coupler and Bus Terminals are attached to commercially available 35 mm mounting rails (DIN rails according to EN 60715) by applying slight pressure: 1. First attach the Fieldbus Coupler to the mounting rail. 2. -
Page 14: Fig. 5 Disassembling Of Terminal
Mounting and wiring Disassembly Fig. 5: Disassembling of terminal Each terminal is secured by a lock on the mounting rail, which must be released for disassembly: 1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doing so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of the bus terminal block easily without excessive force. -

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. 7: 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 18: 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 25: 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. 13: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline. - Page 26 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 27: Access From The User Program
Access from the user program Access from the user program KL401x, KL402x - 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 28: Fig. 16 Mapping In The Interbus Coupler - Example For Kl4012, Kl4022
Access from the user program BK4000 Interbus Coupler The BK4000 Interbus Coupler maps the terminals in the delivery state with 2 bytes per channel: • KL4011, KL4021: 2 bytes of output data • KL4012, KL4022: 4 bytes of output data Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000 configuration software is required. -
Page 29: Mapping In The Bus Coupler
Access from the user program Mapping in the Bus Coupler As already described in the Terminal Configuration section, each Bus Terminal is mapped in the Bus Coupler. This mapping is usually done with the default setting in the Bus Coupler / Bus Terminal. The KS2000 configuration software or a master configuration software (e.g. ComProfibus or TwinCAT System Manager) can be used to change this default setting. -
