Configuring the Controller

From the
Equipment View
, define these properties for controllers:
System Type
,
Process Safety Time
,
Battery Alarm
, and
Remote Fault Reset
.

System Type
AADvance controllers support three types of systems: Standard, Eurocard, or Mixed.
System Type
Description
Standard
IO Bus 1 and 2, each containing 24 slots
Eurocard
IO Bus 1, containing 18 slots
Mixed
IO Bus 1 and 2, each containing 24 slots
The type of system affects the available I/O modules. The
Mixed
controller type enables configuring a standard controller with both
Standard
and
Eurocard
I/O modules.
TIP: The required system type must be set before adding I/O modules to a controller.
Process Safety Time
The process safety time (PST) defines the maximum time in milliseconds that the outputs of a controller remain in the ON state after detecting important diagnostic or application faults. When the defined PST is exceeded, the outputs go into their specified safe states. Set the PST for the controller. The default PST for the controller is 2500 ms. By default, each group of I/O modules inherits the PST from the controller. Also set an alternate PST for each I/O group.
Battery Alarm
The 9110 processor module contains a battery supporting retained variables and the Real Time Clock (RTC) when the system power is turned off. The system contains a processor battery alarm to alert that the battery voltage is low and the battery must be replaced. The battery alarm is enabled by default for
Standard
and
Mixed
controllers.
TIP: The
Battery Alarm
 must be disabled for
Eurocard
controllers.
Remote Fault Reset
The remote fault reset enables resetting faulty processors in the controller without needing to physically press the
Fault Reset
 button located on the T9110 front panel. As well, use the remote fault reset to join processors to a running system. The remote fault reset is required for sub-sea systems since it is impossible to physically manipulate the processors. By default,
Remote Fault Reset
 is disabled (0x00000000). To enable the feature, a non-zero hexadecimal value must be set matching the combined values of the control integers
Allow Remote Fault Reset MSB
 and
Allow Remote Fault Reset LSB
. Possible values range from 0x00000001 to 0xFFFFFFFF. When enabling
Remote Fault Reset
, a warning displays confirming the remote reset of the controller.
TIP: Set the
System Type
 before adding I/O modules. The defined PST must be larger than the execution time for the application to run. By default, the battery alarm is enabled. Disable the alarm for sub-sea systems or other systems lacking a battery. By default, the remote fault reset is disabled. It is recommended to enable the fault reset for sub-sea systems.
To configure the controller system type, process safety time, battery alarm, and remote fault reset
  1. From the
    Equipment View
    , double-click the required controller.
    The
    Equipment
    property page displays.
  2. From the
    Equipment
    property page, click the
    Processor
    tab.
  3. From the
    Processor
    tab, select the required
    System Type
    . Select one of the following:
    • Standard
    • Eurocard
    • Mixed
      The
      Equipment View
       refreshes to display the IO Buses and slots attributed to the specific system type.
  4. From the
    Processor
    tab, in the
    Process Safety Time
     field, type the required value ranging between 20 ms and 60000 ms.
    TIP: For large systems, set the PST for the controller to 1500 ms or more, ensuring sufficient time to educate a second or third processor module.
  5. Set the
    Battery Alarm
     value to
    Enabled
    or
    Disabled
    .
  6. Set the
    Remote Fault Reset
     value to 0x0 (disabled) or a non-zero hexadecimal value (enabled).
    • When enabling the property, a warning displays confirming the action. Click
      Yes
      to enable
      Remote Fault Reset
      .
