NOTE
The performance of the
LAN interface is impacted as more web pages, ports and
sockets are open at the same time. No more than two pages are open at the same time.
The rules for the One Client/Multiple Clients are:
Web Page Not logged-in Maximum of 2 copies of the web page may be open at any time.
You may view but cannot change the power supply operation.
Web Page
You cannot log in as ‘admin’ if a VISA or TCP socket port is already open.
If you are logged in, any VISA, TCP or UDP connections are blocked.
One TCP socket may be open if no
VISA or ‘admin’ web page is open.
UDP sockets are blocked.
Multiple connections of TCP and UDP are
allowed to be open at a time, if no ‘admin’
web page is open.
Up to 3 TCP and 3 UDP connections may be
open at a time.
UDP Socket
VISA Connection Only one VISA port may be open at
Up to two VISA ports may be open at a
Mixed VISA and Sockets N/A Up to two VISA ports and 3 TCP/UDP
Sockets may be open at a time.
4.7.8.4 Input Buffer Requirements
With a controller using TCP or UDP sockets, the power supply can receive commands much faster
than it can process. To make sure the
LAN is not overloaded, it is required that the
controller sometimes sends a query and then waits for the response. The response is the
acknowledgement from the power supply
that it has finished processing all commands.
It is recommended that your controller routinely sends “SYST:ERR?”. This query takes 10 mSec.,
and verifies that all commands have been accepted correctly.
NOTE
When using sockets, it is recommended that no more than 20 SCPI commands may be sent
before a query is sent
4.7.8.5 Message Terminators
When using a program that sends separate SCPI commands through a TCP socket, the socket
drivers may combine all the messages into one long packet. Therefore, it is necessary to add a
terminator character to the end of each SCPI command.
NOTE
All SCPI commands must have a terminator character.
