GENERIC Driver Communications Settings

To establish communication with a device, configure the associated Board, Port and I/O Device in Plant SCADA Studio's Topology activity.

Boards

You do not need to complete any board settings.

Ports

You do not need to complete any port settings.

I/O Devices

Complete the I/O Devices settings as follows.

• I/O Device Name

  A name for your Disk I/O Device, for example: DISK_PLC or MEMORY_PLC.

  Each I/O Device must have a unique name in the Plant SCADA system.

• I/O Device Number

  A unique number for the Disk I/O Device (1-4095)

  Each I/O Device must have a unique number in the Plant SCADA system.

• I/O Device Address

  Leave this property blank if you are using a memory device. If you are using a disk device, enter the path and file name of the disk file, for example: [RUN]:DSKDRV.DSK

  If you are using redundant Disk I/O Devices, you must specify the path to both the primary file and the Standby file in the configuration of both disk I/O Devices.

  For example, if this is the Primary Disk I/O Device enter:

  Primary_File, Standby_File

  If this is the Standby Disk I/O Device enter:

  Standby_File, Primary File

  Where:

  Primary_File is the name (and path) of the Primary Disk I/O Device file. You may use path substitution in this part of the field.

  Standby_File is the name (and path) of the Standby Disk I/O Device file. You may use path substitution in this part of the field.

  Note:
  1. If the specified Disk I/O Device file is not found, Plant SCADA will create a new (empty) file with the specified file name.
  2. To use redundant Disk I/O Devices, you must be using a network that supports peer-to-peer communication.
  3. Disk files must have write permission (on both Primary and Standby servers).
  4. If a corrupt file is detected during a read or write, Plant SCADA will change the mode to read only, and display an error message.
  5. The frequency with which Plant SCADA writes data to the Disk I/O Device(s) is determined by the [DiskDrv]UpDateTime parameter.

• I/O Device Protocol

  Enter GENERIC.

• I/O Device Port Name

  If you are creating a disk device, you must enter DISK.

  If you are creating a memory device, you must enter MEMORY.

• I/O Device Startup Mode

  If you are not using redundant Disk I/O Devices, leave this property blank.

  If you are using redundant Disk I/O Devices, use either:

  PrimaryEnable immediate use of this Disk I/O Device

  StandbyWrite This Disk I/O Device will remain unused until the computer with the primary Disk I/O Device configured becomes inoperable. All write requests sent to the primary Disk I/O Device are also sent to this Disk I/O Device.

  Note: To use StandbyWrite mode, you must also configure an I/O Disk Device in the primary server. Both I/O Devices must have the same I/O Device name and number.

• I/O Device Log Write, Log Read, Cache and Cache Time

  Leave these properties blank.
