Group: Safety_Response_Time
Parameter
Description
Default value
Unit
This parameter makes it possible to manually and individually configure the
safety response time for the module.
The parameters for the safety response time are generally set in the same
way for all stations involved in the application. For this reason, these parame-
ters are configured for the SafeLOGIC controller in SafeDESIGNER. For appli-
cation situations in which individual safety functions require optimal response
time behavior, the parameters for the safety response time can be configured
individually on the respective module.
No
-
Manual_Configuration
Parameter value
Description
Yes
Data from the module's "Safety_Response_Time" group is used to calculate the
safety response time for the module's signals.
No
The parameters for the safety response time are taken from the
"Safety_Response_Time" group on the SafeLOGIC controller.
This parameter describes the synchronization characteristics of the network
being used. They are defined in Automation Studio / Automation Runtime.
Yes
-
Synchronous_Network_Only
Parameter value
Description
Yes
In order to calculate the safety response time, networks must be synchronous and
their cycle times must either be the same or an integer ratio of the cycle times.
No
No requirement for synchronization of the networks
Max_X2X_CycleTime_us
This parameter specifies the maximum X2X cycle time used to calculate the
safety response time.
•
Permissible values: 200 to 25,000 μs (corresponds to 0.2 to 25 ms)
5000
μs
Max_Powerlink_CycleTime_us
This parameter specifies the maximum POWERLINK cycle time used to calcu-
late the safety response time.
•
Permissible values: 200 to 25,000 μs (corresponds to 0.2 to 25 ms)
5000
μs
Max_CPU_CrossLinkTask_
CycleTime_us
This parameter specifies the maximum cycle time for the copy task on the CPU
used to calculate the safety response time. The value 0 indicates that a copy
task is not included for the response time.
•
Permissible values: 0 to 25,000 μs (corresponds to 0 to 25 ms)
5000
μs
Min_X2X_CycleTime_us
This parameter specifies the minimum X2X cycle time used to calculate the
safety response time.
•
Permissible values: 200 to 25,000 μs (corresponds to 0.2 to 25 ms)
200
μs
Min_Powerlink_CycleTime_us
This parameter specifies the minimum POWERLINK cycle time used to calcu-
late the safety response time.
•
Permissible values: 200 to 25,000 μs (corresponds to 0.2 to 25 ms)
200
μs
Min_CPU_CrossLinkTask_
CycleTime_us
This parameter specifies the minimum cycle time for the copy task on the CPU
used to calculate the safety response time. The value 0 indicates that configu-
rations without a copy task are also included for the response time.
•
Permissible values: 0 to 25,000 μs (corresponds to 0 to 25 ms)
0
μs
Worst_Case_Response_Time_us
This parameter specifies the limit value for monitoring the safety response time.
•
Permissible values: 3000 to 5,000,000 μs (corresponds to 3 ms to 5 s)
50000
μs
Node_Guarding_Lifetime
This parameter specifies the maximum number of attempts to be made dur-
ing the time set with parameter "Node_Guarding_Timeout_s". The purpose of
these attempts is to ensure that the module is available.
•
Permissible values: 1 to 255
Note
•
The larger the configured value, the greater the amount of asynchro-
nous data traffic.
•
This setting is not critical to safety functionality. The time for safe-
ly cutting off actuators is determined independently using parameter
"Worst_Case_Response_Time_us".
