Product Overview

2.2 Description of functions

The incremental encoder interface terminal KL5111 enables the connection of any incremental encoders
to the bus coupler or to the controller. The terminal can be operated in two modes (which can be set via
the feature register). The terminal is supplied as an incremental encoder interface. In this mode, the
terminal evaluates the sensor signals A, B, C as a four-fold quadrature decoder. The se nsor is powered
with the available power supply voltage (24 V DC). The KL5111 can also be used as a 16-bit up/down
counter. A period measurement with a resolution of 200 ns of the input A is possible independently of the
set mode.

LED display

The signal LEDs indicate the status of the sensor inputs A, B, C. The corresponding LED is activated with
every high signal at the input.

Connections

A, B, zero signals
Shield connection
24 V

power contacts for sensor powering with automatic potential bridging to the neighboring terminal

DC

Operation modes

These can be set via the feature register (default: incremental encoder):
A, B, zero pulse incremental encoder (default)
Up/down counter with:

• A = Count , the positive edges of the input pulses are counted

• B = = Up/down input

B = 0: up counting direction
B = 1: down counting direction

• C = Gate-Eingang
C = 0: counter enabled
C = 1: counter disabled

Functions

• Counting

• Counter setting

• Arming the zero pulse and storing the valid value

• Determining the period between two pulses with a resolution of two 200 ns (the time between two

positive edges of the input signal A is evaluated)

• Indication of the input signals A, B, C, in the process data

• Indication of a counter overflow or underflow.

Process data

The KL5111 occupies 6 bytes of input data and 6 bytes of output data. The control/status byte is at the
least significant byte offset. The data word D0/D1 contains the counter word (read/set) and the data word
D3/D4 contains the latch word (read).
