Still only one control system can be connected to the constant
temperature equipment via the Ethernet interface. It is not possible
to activate the equipment simultaneously from multiple systems.
As soon as you select the PC control option in the menu of the
constant temperature equipment, you can establish the connection
from the control system.
The constant temperature equipment is connected via the Ethernet inter-
face and can be accessed from the network or single system. The network
settings have been configured manually.
1.
Enter the number for the
Port
.
The value determines which port number is used to establish the
connection to the
Process SST
process interface. Port 54321
is the factory default setting, all free port numbers between
49152 – 65535 are permitted.
2.
Activate the
Process SST
function:
Open the
Modules
Ethernet
Process SST off / on
menu.
Select the option
on
and confirm your selection.
A terminal program can be used to establish the connection to the constant
temperature equipment. For example, the freeware
RealTerm
, which can be
downloaded from the following address: https://realterm.sourceforge.io/
The following settings are required:
1.
Start the terminal program on the connected system.
2.
Open the
Port
tab.
3.
Enter the configured IP address and port number of the Ethernet
interface into the
Port
field. The IP address and port number must be
separated by a colon.
4.
Send a test command such as the read command "TYPE” to the
constant temperature equipment.
If the device type designation, for example "ECO", is received in
response, the connection has been set up correctly.
7.4.2 Setting up the virtual COM port
Set up a virtual COM port on the connected PC for easy communication via
the activated process interface.
The software used to control the constant temperature equipment must
be capable of transmitting serial commands via Ethernet. If the software
cannot do this, install driver software on the control system that emulates
the Ethernet interface as a serial port. The "Virtual Serial Port Emulator" is an
example of suitable software and is also available as freeware.
"Virtual Serial Port Emulator" software is not a LAUDA product.
LAUDA cannot therefore offer any guarantees or support for the
software.
