Device Properties
The Properties page includes the following settings:
Setting
Description
In the Properties section:
Number
The relative position of the device in the list, from 0 to 127.
By default, this number is assigned sequentially to devices in the project, beginning with the number 000 that is assigned to the first local slave.
Active Configuration
  • Enable: adds this device to the Control Expert project configuration
  • Disable: removes this device from the Control Expert project configuration
NOTE:
  • Changing this setting also changes the addresses of items in project memory. Selecting Enable adds the device’s inputs and outputs to project memory; selecting Disable removes these inputs and outputs from memory.
  • Alternatively, if you enable the I/O Communication Control service, you can turn ON and OFF the connection between a communication module and a remote device by toggling the output CONTROL_BIT for that connection. This leaves unchanged the size of the project’s input and output data images.
In the IO Structure Name section:
Input area:
Instance Variable Name
The editable base name for input variables. By default, it is the concatenation of:
  • the string DEVICE_
  • the device number
  • the suffix _IN
Structure Name
The read-only name for input structures. By default, it is the concatenation of:
  • The prefix T_
  • the string DEVICE_
  • the device number
  • the suffix _IN
Output area:
Instance Variable Name
The editable base name for output variables. By default, it is the concatenation of:
  • the string DEVICE_
  • the device number
  • the suffix _OUT
Structure Name
The read-only name for input structures. By default, it is the concatenation of:
  • The prefix T_
  • the string DEVICE_

  • the suffix _OUT
Default Name button
Restores the default variable and structure names.
In the Items Management section of the page, edit the following:
Import mode
  • Automatic: I/O items are taken from the device DTM and updated if the items list in the device DTM changes. Items cannot be edited in the Device Editor.
  • Manual: I/O items are added when the device DTM is first added to Control Expert. Thereafter, all I/O item edits are made manually in the Device Editor. Changes to the device DTM do not impact the I/O items list.
Reimport Items
Imports the I/O items list from the device DTM, overwriting any manual I/O item edits. Enabled only when Import mode is set to Manual.
