●
TCPIP designates the network protocol used
●
host address is the IP address or host name of the device
●
LAN device name defines the protocol and the instance number of a sub-instru-
ment;
– inst0 selects the VXI-11 protocol (default)
– hislip0 selects the newer HiSLIP protocol
●
INSTR indicates the instrument resource class (optional)
●
port determines the used port number
●
SOCKET indicates the raw network socket resource class
Example:
●
Instrument has the IP address 192.1.2.3; the valid resource string using VXI-11
protocol is:
TCPIP::192.1.2.3::INSTR
●
The instrument name is RSFSV; the valid resource string is:
TCPIP::RSFSV::INSTR
●
A raw socket connection can be established using:
TCPIP::192.1.2.3::5025::SOCKET
●
The DNS host name name is FSV-123456; the valid resource string using HiSLIP
is:
TCPIP::FSV-123456::hislip0
Identifying instruments in a network
If several instruments are connected to the network, each instrument has its own IP
address and associated resource string. The controller identifies these instruments by
means of the resource string.
For details on configuring the LAN connection, see Chapter 11.2.6, "Setting Up a Net-
work (LAN) Connection", on page 623.
VXI-11 Protocol
The VXI-11 standard is based on the ONC RPC (Open Network Computing Remote
Procedure Call) protocol which in turn relies on TCP/IP as the network/transport layer.
The TCP/IP network protocol and the associated network services are preconfigured.
TCP/IP ensures connection-oriented communication, where the order of the
exchanged messages is adhered to and interrupted links are identified. With this proto-
col, messages cannot be lost.
HiSLIP Protocol
The HiSLIP (High Speed LAN Instrument Protocol) is the successor protocol for
VXI-11 for TCP-based instruments specified by the IVI foundation. The protocol uses
two TCP sockets for a single connection - one for fast data transfer, the other for non-
sequential control commands (e.g. Device Clear or SRQ).
HiSLIP has the following characteristics:
