Safety view parameters

The
Safety
 view includes these parameters:
Parameter
Description
Safety Input
Requested Packet Interval (RPI)
Enter the RPI for the safety input connection.
For simple timing constraints, set the Connection Reaction Time Limit solely by adjusting the RPI, as necessary. For more complex timing constraints, set the Connection Reaction Time Limit by using the
Advanced
 button to access the necessary parameters.
Safety Input
Connection Reaction Time Limit
Displays the predicted maximum period of safety packets on the safety input connection.
If the Max Observed Connection Reaction Time exceeds the Connection Reaction Time Limit, a connection fault occurs.
Safety Input
Max Observed Network Delay - Time
Displays the value generated by the controller for safety input (and safety consume) connections.
The default value is 0. The Max Observed Network Delay value is updated automatically at a rate similar to the rate used by the Max Scan Time. This value is blank when working offline. The value is ?? when the status is Faulted or Connecting.
Safety Input
Max Observed Network Delay - Action
Resets the Max Connection Reaction Time value in the controller (for input connections).
This field appears shaded in Offline mode or when online and the status is not Running.
Safety Output
Requested Packet Interval (RPI)
Displays the RPI for the safety output connection.
The RPI is fixed to the Safety Task Period. If the Connection Reaction Time Limit is not acceptable, either the Safety Task Period must be adjusted (via the Safety Task Properties view) or adjust the Advanced Connection Reaction Time Limit to attempt to achieve the needed time limit.
Safety Output
Connection Reaction Time Limit
Displays the predicted maximum period of safety packets on the safety output connection.
If the Max Observed Connection Reaction Time exceeds the Connection Reaction Time Limit, a connection fault occurs.
Safety Output
Max Observed Network Delay - Time
Displays the value generated by the output device for safety output connections.
The default value is 0. The Max Observed Network Delay value is updated automatically at a rate similar to the rate used by the Max Scan Time. This value is blank when working offline. The value is ?? when the status is Faulted or Connecting.
Safety Output
Max Observed Network Delay - Action
Click to reset the Max Connection Reaction Time value in the output device (for output connections).
This field appears shaded in Offline mode or when online and the status is not Running.
Advanced
Opens the
Advanced Connection Reaction Time Limit Configuration
 dialog box to configure the connection reaction time limit.
Configuration Ownership
Indicates whether the current controller owns the configuration of the current device.
The value is read directly from the device and is available only online. When working offline, the label appears shaded and a value does not appear. The value is updated when you open the dialog box and when you change to or from Run mode.
  • Local is displayed when the current controller owns the device configuration.
  • Remote (SNN: nnnn_nnnn_nnnn, Address: mm) is displayed when another device owns the device configuration. The owning device Safety Network Number is
    nnnn_nnnn_nnnn
    . The node or slot number is
    mm
    .
  • When read fails, ?? is displayed, typically because the device status is faulted or connecting.
Refresh Ownership
Retrieves and displays the latest ownership information.
Reset Ownership
Opens the Reset Ownership confirmation dialog box.
If the reset ownership is confirmed, the device enters its out-of-box configuration. The device is not owned. It becomes owned by the first originator that successfully configures the device. If the device has connections or has been locked from RSNetWorx for DeviceNet, the reset prompt is rejected.
This field is enabled when safety secured to support the device replacement option. This field appears shaded when pending edits exist in the device properties or when working offline.
Enable Configuration Signature
Select this checkbox to enable the Configuration Signature options.
Clearing the checkbox causes a warning to display and causes the
ID
,
Date
, and
Time
 fields to appear shaded.
ID
Depending on the safety device being configured, displays or specifies the 32-bit unsigned number in hexadecimal based on the ID associated with the desired device as shown in an external configuration program.
When selecting the
Enable Configuration Signature
 checkbox:
  • The last ID value is loaded and the ID value is enabled based on the state of the controller.
  • If the ID value was not previously set, the
    ID
     field is blank.
  • If the ID value was previously set but not applied to the profile, the ID value displays.
  • If the ID value was previously set and unchanged, the ID value displays.
This field appears shaded in Run and Safety Secured modes and when the
Enable Configuration Signature
 checkbox is cleared.
Date
Depending on the safety device being configured, displays or specifies the date associated with the desired device as shown in an external configuration program. The date must be in the
mm/dd/yyyy
 or
dd/mm/yyyy
 format, based on localization settings.
When selecting the
Enable Configuration Signature
 checkbox:
  • The last date value is loaded and the date value is enabled based on the state of the controller.
  • If the date value was not previously set, the
    Date
     field is blank.
  • If the date value was previously set but not applied to the profile, the date value displays.
  • If the date value was previously set and unchanged, the date value displays.
This field appears shaded in Program, Remote Program, and Remote Run modes and when the
Enable Configuration Signature
 checkbox is selected.
Time
Depending on the safety device being configured, displays or specifies the time associated with the desired device as shown in an external configuration program.
When selecting the
Enable Configuration Signature
 checkbox:
  • The last time value is loaded and the time value is enabled based on the state of the controller.
  • If the time value was not previously set, the
    Time
     field is blank.
  • If the time value was previously set but not applied to the profile, the time value displays.
  • If the time value was previously set and unchanged, the time value displays.
This field appears shaded in Program, Remote Program, and Remote Run modes and when the
Enable Configuration Signature
 checkbox is selected.
Copy
Copies the Configuration Signature ID, Date, and Time value.
Paste
Pastes the copied Configuration Signature ID, Date, and Time value.
