Yokogawa DX Serial Driver

Modem Settings

l

Modem

:  Specify the installed modem to be used for communications.

l

Connect Timeout

:  Specify the amount of time to wait for connections to be established before

failing a read or write. The default is 60 seconds.

l

Modem Properties

:  Configure the modem hardware. When clicked, it opens vendor-specific modem

properties.

l

Auto-Dial

:  Enables the automatic dialing of entries in the Phonebook. The default is Disable.

For

more information, refer to "Modem Auto-Dial" in the server help.

l

Report Comm. Errors

:  Enable or disable reporting of low-level communications errors. When

enabled, low-level errors are posted to the Event Log as they occur. When disabled, these same
errors are not posted even though normal request failures are. The default is Enable.

l

Close Idle Connection

:  Choose to close the modem connection when there are no longer any tags

being referenced by a client on the channel. The default is Enable.

l

Idle Time to Close

:  Specify the amount of time that the server waits once all tags have been

removed before closing the modem connection. The default is 15 seconds.

Operation with no Communications

l

Read Processing

: Select the action to be taken when an explicit device read is requested. Options

include Ignore and Fail. Ignore does nothing; Fail provides the client with an update that indicates
failure. The default setting is Ignore.

Channel Properties — Write Optimizations

As with any server, writing data to the device may be the application's most important aspect. The server
intends to ensure that the data written from the client application gets to the device on time. Given this goal,
the server provides optimization properties that can be used to meet specific needs or improve application
responsiveness.

Write Optimizations

Optimization Method

: controls how write data is passed to the underlying communications driver. The

options are:

l

Write All Values for All Tags

:  This option forces the server to attempt to write every value to the

controller. In this mode, the server continues to gather write requests and add them to the server's
internal write queue. The server processes the write queue and attempts to empty it by writing data
to the device as quickly as possible. This mode ensures that everything written from the client
applications is sent to the target device. This mode should be selected if the write operation order or
the write item's content must uniquely be seen at the target device.

l

Write Only Latest Value for Non-Boolean Tags

: Many consecutive writes to the same value can

accumulate in the write queue due to the time required to actually send the data to the device. If the
server updates a write value that has already been placed in the write queue, far fewer writes are
