SAFEIO.24 Safety relay 2 output Sets the digital output for safety relay 2.
See also parameter SAFEIO.21 Safety relay
1 output.
Note: The output must always be redundant.
Otherwise the feedback signal of the safety
relay is not used (see SAFEIO.25 Safety
relay 2 feedback).
None
None No output connected
DO X113:7 & X114:7 Redundant output X113:7 & X114:7
DO X113:8 & X114:8 Redundant output X113:8 & X114:8
DO X113:9 & X114:9 Redundant output X113:9 & X114:9
SAFEIO.25 Safety relay 2
feedback
Sets the digital feedback input of safety
relay 2.
Parameter SAFEIO.26 Safety relay 2
feedback type sets the type of the feedback
input.
None
None No input connected
DI X113:1 Single input X113:1
DI X113:2 Single input X113:2
DI X113:3 Single input X113:3
DI X113:4 Single input X113:4
DI X114:1 Single input X114:1
DI X114:2 Single input X114:2
DI X114:3 Single input X114:3
DI X114:4 Single input X114:4
SAFEIO.26 Safety relay 2
feedback type
Sets the type of the feedback signal for
safety relay 2.
Note: The feedback delay is 800 ms for both
feedback types, that is, a feedback signal
from the safety relay must be received within
800 ms.
Mechanicall
y linked NC
contacts
Mechanically linked
NC contacts
Feedback of the safety relay is NC (inverted
state compared with the relay).
Mechanically linked
NO contacts
Feedback of the safety relay is NO (same
state compared with the relay).
SAFEIO.31 DI diagnostic pulse
length
Sets the length of the diagnostic pulse for
digital inputs.
1ms
0.5 ms Length of the diagnostic pulse is 0.5 ms.
1 ms Length of the diagnostic pulse is 1 ms.
2 ms Length of the diagnostic pulse is 2 ms.
SAFEIO.32 DI diagnostic pulse
period
Sets the time during which the FSO module
must receive at least one whole diagnostic
pulse.
10,000 ms
