Socket communication
TCPIP::<IP address or hostname>::port::SOCKET
●
port determines the used port number
●
SOCKET indicates the raw network socket resource class
Socket communication requires the specification of the port (commonly referred to as
port number) and of "SOCKET" to complete the VISA resource string with the associ-
ated protocol used.
The default port for socket communication is port 5025.
Example:
A power sensor has the IP address 10.111.11.20; the valid resource string using
VXI-11 protocol is:
TCPIP::10.111.11.20::INSTR
The DNS host name is nrp18sn-100001; the valid resource string is:
TCPIP::nrp18sn-100001::hislip0 (HiSLIP)
TCPIP::nrp18sn-100001::inst0 (VXI-11)
A raw socket connection can be established using:
TCPIP::10.111.11.20::5025::SOCKET
TCPIP::nrp18sn-100001::5025::SOCKET
11.2 Status reporting system
The status reporting system stores all information on the current operating state of the
sensor, and on errors which have occurred. This information is stored in the status reg-
isters and in the error queue. You can query both with the commands of the STATus
subsystem.
11.2.1 Overview
Fig.11-1 shows the hierarchical structure of information in the status registers.
