State of the K-Bus

An internal bus or Bus Terminal error is indicated in the K-Bus state. A more precise fault description can be obtained

via a function block (in preparation). To this end, link the K-Bus state variable with your PLC program.

Error bit Description Error type

0 No error No ERROR.

Bit 0 K-Bus error ERROR

Bit 2 K-Bus is re-triggered NOTE

Read the K-Bus state via ADS

In the default configuration and TwinCAT configuration you can read the K-Bus state about ADSREAD.

Parameter ADSREAD function block Description

NetID local - empty string

Port 1

IndexGroup 16#0006

IndexOffset 16#000C_9000
