4.5 Configuration of Line Diagnosis
4.5.1 Line Diagnosis for Lamp Loads and Inductive Loads
To detect short-circuits, a 24 V pulse (normal voltage level) is sent to the output circuit for the
duration of 500 µs. After this time, a 10 V pulse is sent to detect open-circuits for the duration of
the monitoring time.
To configure the line diagnosis, the following parameters must be set in SILworX and the
following signals must be set in ELOP II Factory Hardware Management.
SILworX ELOP II Factory Value
DO.LM period DO.LSLB Interval Freely configurable
1…100 s
DO.Line Monitoring Time DO.LSLB Monitoring Time Freely configurable
0…50 ms
Default: 0 ms
2-pole [BOOL] -> DO[xx].2-Pole TRUE
Line Monitoring [BOOL] -> DO[xx].LSLB Monitoring TRUE
DO[xx].SC Monitoring with
Reduced Voltage DO[xx].SC Monitoring with
Reduced Voltage FALSE

4.5.2 Line Diagnosis for Ohmic, Capacitive Loads
To diagnose the line for ohmic capacitive loads, the remote I/O sends a 10 V test pulse
(reduced voltage level) to the output circuit for the duration of the monitoring time. This type of
line diagnosis is particularly recommended for ohmic and ohmic capacitive loads. With inductive
loads or lamp loads, error messages related to the short-circuit may be generated.
To configure the line diagnosis, the following parameters must be set in SILworX and the
following signals must be set in ELOP II Factory Hardware Management.
SILworX ELOP II Factory Value
