Data Communication Settings
55
Output 2
This parameter is read-only if the scanner Output 2 is set to Use Local. If the scanner Output 2 is set to Use External
Fieldbus, then this parameter can be checked to allow the Fieldbus Master to drive the scanner Output 2 via bit 1 in
Byte 0 (LSB) of the Output Area.
For Ethernet/IP under the TCP/IP Services branch, the Fieldbus Master can drive Output 2 using Assembly Object
Instances.
TCP/IP Services
UserSocket #n
The TCP/IP protocol provides two (user-defined) application sockets for communication. For further details refer to the
following bibliography:
Internetworking with TCP/IP, vol. I (chap. 20), by Douglas E. Comer
UNIX, network programming, by W. Richards Stevens
All the parameters managing the Heartbeat are available in the Heartbeat parameters group.
Status
Enables the TCP/IP User Socket #n.
Data Tx
If enabled (checked), data from the scanner will be transmitted on the TCP/IP User Socket.
Heartbeat
This parameter enables/disables transmission of the Heartbeat message used to signal device or system status at
regular intervals. The Heartbeat message is independent from Data Tx and can be enabled even if data is not sent on
the TCP/IP User Socket (Data Tx - disabled).
Selections:
Disable
the Heartbeat message is not transmitted
Enable Unconditioned
the Heartbeat message is always transmitted, even if
communication is still active
Enable Conditioned
the Heartbeat message is transmitted only when there is no
communication
Type
It defines the type of the socket:
Selection:
Server
For all TCP/IP Host Interface Modules, the station waits for connection and can
communicate with one single client at a time. If a second connection is opened by
the same peer machine with an application socket of type server TCP, this new
connection will replace the first.
Client
The station tries a connection towards the server.
Server_address
This parameter is available only when the socket is configured as a Client. It defines the IP address of the server to
which the client tries to connect.
