KL8524 - Register description

The registers are used for the parameterization of the Bus Terminals and are available for each channel. They can be read or written by means of the register communication.

R7: Command register

To execute a standard command, the user code word 0x1235 must be entered in register R31.

Command 0x7000: Restore Factory Settings

Entering 0x7000 in register R7 restores the delivery state for the following registers.

  • Register R32: 0x0000
  • Register R33: 0x0000
  • Register R34: 0x0000
  • Register R35: 0x0000
  • Register R36: 0x0000
  • Register R37: 0x0000
  • Register R38: 0x0000
  • Register R39: 0x0000
  • Register R40: 0x0000
    to
  • Register R63: 0x0000

R8: Terminal description

The name of the terminal is contained in register R8.
KL8524: 0x214C (8524dec)

R9: Firmware version

Register R9 contains the ASCII coding of the terminal's firmware version, e.g. 0x3141 = '1A'. The '0x31' corresponds here to the ASCII character '1', while the '0x41' represents the ASCII character 'A'.
This value cannot be changed.

R12: Minimum data length of a channel

R16: Hardware version number

Register R16 contains the hardware version of the terminal.

R31: Code word register

  • If you write values into the user registers without first entering the user code word (0x1235) into the code word register, the terminal will not accept the supplied data.
  • If you write values into the user registers and have previously entered the user code word (0x1235) in the code word register, these values are stored in the RAM registers and in the SEEPROM registers and are therefore retained when the terminal is restarted.

The code word is reset when the terminal is restarted.

R32: Enable PLC Set LED

Using this register you can allow the PLC to set the status LEDs of the individual channels.

2) Switchover delay: A delay time can be specified, after which the switch position becomes effective.

Delay time in output mode 1

Output mode 1 can be used if the two outputs may not be switched on at the same time (e.g. fan motor with star-delta switching).

The delay time starts in output mode 1 when changing from

  • switch position 1 to switch position 2
  • switch position 2 to switch position 1
  • Fast switching from 0 to 2 or from 2 to 0 always takes place via switch position 1 and thus also starts the delay time.

Examples:

  • Output 1 switches on immediately when the three-stage switch is switched from 0 to 1.
  • The delay time starts when the three-stage switch is switched from 1 to 2. No output is switched during the delay time. Output 2 is switched on when the delay time expires.
  • The delay time starts when the three-stage switch is switched back from 2 to 1. No output is switched during the delay time. Output 1 is switched on when the delay time expires.
  • Switching from 1 or 2 to 0 takes place immediately. Both outputs are switched off immediately.
  • If the switch is switched back to the previous switch position during the delay time, the previous output immediately becomes active again.

Delay time in output mode 2

Output mode 2 can be used if there has to be a minimum time before output 2 is switched on (e.g. consumers with two stages that would have an excessively high starting current if switched on directly in stage 2).

The delay time starts output mode 2 when changing from

  • switch position 1 to switch position 2
  • Fast switching from 0 to 2 always takes place via switch position 1 and therefore also starts the delay time.

Examples:

  • Output 1 switches on immediately when the three-stage switch is switched from 0 to 1.
  • The delay time starts when the three-stage switch is switched from 1 to 2. Output 1 remains switched on as long as the delay time is running. Output 2 is additionally switched on when the delay time expires.
  • The switching back of the three-stage switch from 2 to 1 takes place immediately. Output 2 switches off, output 1 remains switched on.
  • Switching from 1 or 2 to 0 takes place immediately. Both outputs are switched off immediately.
  • The delay time starts again if the switch is switched from 1 to 2 when the delay time is running.
