Terminal configuration

4 KL1512

2.2 Functional Description

The input terminal KL1512 counts binary pulses and transmits the current

value to the higher-level control system.

The maximum input frequency is limited to 1 kHz. The minimum pulse

width of the input signal is 500 microseconds. This means, not mark nor

space of the input signal may be shorter than 500 microseconds!

The counters react to the rising edge of the input signal.

LED display The LEDs indicate the states of inputs 1 and input 2.

Process data

Standard output format

6 bytes (2 bytes of user information data and 1 control/status byte per

channel ) are mapped. The process data presents themselves as follows

per channel:

• 1 Byte Control/Status

• 16 Bit unsigned Integer

Mapping of the terminal is described in further detail in the appendix.

3 Terminal configuration

Note

The terminal can be configured and parameterized by way of the internal

terminal’s data is mapped differently in the bus coupler’s memory

depending on the type of the bus coupler and on the set mapping

configuration (e.g. Motorola/Intel format, word alignment etc.).

Contrary to the analog and output terminals, in the case of the KL1512 the

control and status byte is always also mapped, regardless of the field bus

system used.

Lightbus coupler BK2000 When using the Lightbus coupler BK2000, the KL1512 is automatically

mapped with 6 bytes of input data and 6 bytes of output data.
