7.3.2 Checking the network connection
You can use the
ping
console command from a connected system to easily
check whether the interface on the constant temperature equipment is
available. Here, a single request (echo request) is sent to the configured local
IP address. If the equipment is available, it usually returns four responses
together with the respective transmission time.
The constant temperature equipment is switched on and connected to a
single system or the network.
1.
Open the command line interpreter (console) on a connected system.
Starting the console
A command line interpreter can be used on every operating
system. On a Windows 10 operating system, for example, it
can be accessed as follows:
Start (right-click)
Run
cmd.exe
2.
Enter the command "ping” and the IP address of the constant tem-
perature equipment:
Syntax: "
ping XXX.XXX.XXX.XXX
"
Example:
ping 120.0.1.12
.
3.
Press [Enter] to confirm the entry
If available, the constant temperature equipment responds to the
request immediately.
If the remote station is unavailable, check whether the following criteria have
been met:
The constant temperature equipment is connected to the same network
as the test system.
The test address corresponds to the address displayed in the menu of
the constant temperature equipment.
The configured network settings are correct.
If necessary, contact your system administrator.
7.4 Setting up the process interface
7.4.1 Activating the process interface (Process SST on/off)
The process interface option is only available when the DHCP client
is deactivated. It ensures that the constant temperature equipment
is always controlled via a fixed IP address.
The Ethernet interface can be configured as a process interface for con-
trolling and monitoring the constant temperature equipment via Ethernet.
The equipment can be accessed from your own application; the LAUDA
command set is used for data transmission.
