Yokogawa DX Serial Driver
Inter-Device Delay
: Specify the amount of time the communications channel waits to send new requests to
the next device after data is received from the current device on the same channel. Zero (0) disables the
delay.
Note:
This property is not available for all drivers, models, and dependent settings.
Device Properties — General
A device represents a single target on a communications channel. If the driver supports multiple controllers,
users must enter a device ID for each controller.
Identification
Name
: This property specifies the name of the device. It is a logical user-defined name that can be up to
256 characters long, and may be used on multiple channels.
Note
: Although descriptive names are generally a good idea, some OPC client applications may have a
limited display window when browsing the OPC server's tag space. The device name and channel name
become part of the browse tree information as well. Within an OPC client, the combination of channel name
and device name would appear as "ChannelName.DeviceName".
For more information, refer to "How To... Properly Name a Channel, Device, Tag, and Tag Group" in server
help.
Description
: User-defined information about this device.
Many of these properties, including Description, have an associated system tag.
Channel Assignment
: User-defined name of the channel to which this device currently belongs.
Driver
: Selected protocol driver for this device. This property specifies the driver selected during channel
creation. It is disabled in the channel properties.
Model
: This property specifies the specific type of device that is associated with this ID. The contents of the
drop-down menu depends on the type of communications driver being used. Models that are not supported
by a driver are disabled. If the communications driver supports multiple device models, the model selection
can only be changed when there are no client applications connected to the device.
Note:
If the communication driver supports multiple models, users should try to match the model
selection to the physical device. If the device is not represented in the drop-down menu, select a model that
conforms closest to the target device. Some drivers support a model selection called "Open," which allows
users to communicate without knowing the specific details of the target device. For more information, refer
to the driver help documentation.
