KL2502, KL2512 - Dual Channel Pulse Width Output Terminals, 24 V DC

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.). In contrast to the analog input and output terminals, in the KL2502 the control byte and the status byte are always mapped, irrespective of the fieldbus system used.

 

BK2000 Lightbus coupler

With the BK2000 Lightbus coupler, the control/status byte is always mapped in addition to the data bytes (i.e. for all analog terminals). This is always located in the low byte at the offset address of the terminal channel.

Profibus coupler BK3000

With the BK3000 Profibus coupler, the KL2502 is represented by 6 bytes of input data and 6 bytes of output data (3 bytes per channel) as standard. Thus, 2 bytes of user data and 1 byte control/status data are mapped per channel.

BK4000 Interbus Coupler

In delivery state, the BK4000 Interbus Coupler maps the terminals with 6 bytes of input data and 6 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.

Other Bus Couplers and further information

Further information about the mapping configuration of Bus Couplers can be found in the Appendix of the respective Bus Coupler manual under Master configuration.

The chapter on Mapping in the Bus Coupler contains an overview of possible mapping configurations, depending on the configurable parameters.

 
Parameterization with KS2000
The KS2000 configuration software can be used for parameterizations via the serial interface of the Bus Coupler, independent of the fieldbus system.
