applies to all drivers equally.
This is a Read/Write tag.
_InterRequestDelay
The _InterRequestDelay is a tag that allows the time interval between
device transactions to be changed on the fly. The _InterRequestDelay is
defined as a Long data type. The valid range is 0 to 30000 milliseconds.
This parameter tag only applies to drivers that support this feature.
This is a Read/Write tag.
_EncapsulationIp
Class: Parameter Tag
The _EncapsulationIp tag allows the IP of a remote terminal server to
be specified and changed on the fly. This parameter tag is only
available on serial drivers that support
mode. The _EncapsulationIp is defined as a string data
type, allowing the entry of an IP address number. The server will reject
entry of invalid IP addresses. This tag is only valid for a Serial driver in
Ethernet Encapsulation mode.
This is a Read/Write tag.
_EncapsulationPort
Class: Parameter Tag
The _EncapsulationPort tag allows the port number of the remote
terminal server to be specified and changed on the fly. The
_EncapsulationPort is defined as a long data type. The valid range is 0
to 65535. The port number entered in this tag must match that of the
desired remote terminal server for proper Ethernet Encapsulation to
occur. This tag is only valid for a Serial driver in Ethernet Encapsulation
mode.
This is a Read/Write tag.
_EncapsulationProtocol
Class: Parameter Tag
The _EncapsulationProtocol tag allows the IP protocol used for Ethernet
Encapsulation to be specified and changed on the fly. The
_EncapsulationProtocol is defined as a string data type. Writing either
"TCP/IP" or "UDP" to the tag specifies the IP protocol. The protocol
used must match that of the remote terminal server for proper
Ethernet Encapsulation to occur. This tag is only valid for a Serial driver
in Ethernet Encapsulation mode.
This is a Read/Write tag.
_AutoCreateTagDatabase
Class: Parameter Tag
The _AutoCreateTagDatabase tag is a Boolean tag that is used to
initiate the automatic OPC tag database functions of this driver for the
device to which this tag is attached. When this tag is set TRUE, the
communications driver will attempt to automatically generate an OPC
tag database for this device. This tag will not appear for drivers that do
not support Automatic OPC Tag Database Generation.
This is a Read/Write tag.
_Enabled
Class: Parameter Tag
The _Enabled tag is a Boolean tag that allows the active state of the
device to be turned On or Off. When this tag is set FALSE, all other
user-defined tags and data from this device will be marked as invalid
and Writes will not be accepted for the device. When this tag is set
TRUE, normal communications will occur with the device.
This is a Read/Write tag.
_Error
Class: Status Tag
The _Error tag is a Boolean tag that returns the current error state of
the device. When FALSE, the device is operating properly. When set
TRUE, the driver has detected an error when communicating with this
device. A device enters an error state if it has completed the cycle of
request timeouts and retries without a response.

This is a Read Only tag.
_NoError
Class: Status Tag
The _NoError tag is a Boolean tag that returns the current error state
of the device. When TRUE, the device is operating properly. When
FALSE, the driver has detected an error when communicating with this
device. A device enters an error state if it has completed the cycle of
