General coupler configuration (table 0)
Table 0 of the Bus Coupler contains the data for the general coupler configuration. It is not, as a general rule,
necessary to change this; however, for special applications it is possible to change the settings using the
KS2000 configuration software, or through direct access via register communication. The write protection
must first be removed in order to do this (see above).
The relevant register entries are described below:
K-Bus configuration
Table 0, register 2, contains the K-Bus configuration, and is coded as follows (default value: 0x0006):
MSB
0 0 0 0
A: Auto-reset
If there is a K-Bus error, attempts are made cyclically to start the K-Bus up again through a reset. If
emergency telegrams and guarding are not evaluated, activation of auto-reset can lead to output and input
information being lost without that loss being noticed.
0: No auto-reset (default)
1: Auto-reset active
G: Device diagnostics
Reporting (by means of emergency telegram), that, for example
- a current input is open circuit (with diagnostics)
- 10 V exceeded at a 1-10V input terminal
0: Device diagnostics switched off
1: Device diagnostics active (default)
D: Diagnostic data
from digital terminals is included in the process image (e.g. KL2212). This flag is only evaluated when device
diagnostics is active (see above).
0: Do not display
1: Display (default)
Process image description
Table 0, register 3, contains the process image description, and is coded as follows (default value: 0x0903):
MSB
0 0 0 0
k0...k1: Reaction to K-Bus errors
0,2: Inputs remain unchanged (default = 2);
1: Set inputs to 0 (TxPDO with zeros is sent)
f0...f1: Reaction to fieldbus error
0: Stop the K-Bus cycles, watchdog in the terminals triggers, fault output values become active. The old
output values are initially set during a restart.
1: Set outputs to 0, then stop the K-Bus cycles (default). 2: Outputs remain unchanged.
