Ethernet Encapsulation
This driver supports Ethernet Encapsulation, which allows the driver to communicate with serial devices
attached to an Ethernet network using a terminal server or device server. Ethernet Encapsulation mode is
invoked by selecting it from the COM ID dialog on the Channel Properties page. More help on Ethernet
Encapsulation can be found in the main OPC Server help file. When used directly with a serial port, this driver
supports only a single connection to a single controller per serial port. When operating in the Ethernet
Encapsulation mode, the driver will support up to 31 controllers per channel. In this mode a single controller can
be paired with a terminal server/device server to form a single node.
Flow Control
When using an RS232/RS485 converter, the type of flow control that is required will depend upon the needs of
the converter. Some converters do not require any flow control and others will require RTS flow. Consult the
converter's documentation in order to determine its flow requirements. We recommend using an RS485
converted that provides automatic flow control.
Note: When using the manufacturer's supplied communications cable, it is sometimes necessary to choose a
flow control setting of RTS or RTS Always under Channel Properties. For the Simatic/TI 505 Serial select RTS_
ALWAYS for either protocol.
Cable Connections
Modem Setup
This driver supports modem functionality. For more information, please refer to the topic "Modem Support" in the
OPC Server Help documentation.
