Configuring I/O Modules for AADvance Applications

Configure the modules after adding the required I/O modules to the I/O bus of a controller. The following are the types of I/O modules in an AADvance controller, each requiring different information to complete their configuration:
  • Digital Inputs
  • Analog Inputs
  • Digital Outputs
  • Analog Outputs
For all types of I/O modules, configure the process safety time (PST) and status variable.
When configuring I/O modules, define the process safety time (PST). 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. By default, the PST is inherited from the controller. Also specify a smaller PST for each I/O group.
When configuring an I/O module, use a status variable to get data from the module such as the health, ready, online, run, and shutdown statuses. The status variable must have the structure data type T9K_TA_GROUP_STATUS.
Task
Procedure
Configure process safety time for an I/O module
  1. From the
    Equipment View
    , expand the IO bus and double-click the required I/O module.
    The
    Equipment
    property page displays.
  2. From the
    Equipment
    property page, in the module-specific tab, clear the
    Inherit
    option.
  3. In the
    Process Safety Time
     field, type the required value ranging between 20 ms and 60000 ms. The value must be smaller than the PST set for the controller.
Wire a status variable to an I/O module
  1. In the
    Dictionary
    , declare a variable with the following properties:
    • Data Type: T9K_TA_GROUP_STATUS
    • Direction: VarInput
  2. In the
    Equipment View
    , expand the IO bus and double-click the required I/O module.
    The
    Equipment
    property page displays.
  3. From the
    Equipment
    property page, in the module-specific tab, click eqv_spv in the
    Status Variable
     field.
    The
    Variable Selector
     displays.
  4. In the
    Variable Selector
    , select the required variable and then click
    OK
    .
The following example displays the module-specific tab to define the PST and wire the status variable for an I/O module:
