IKA VC 10 lite Guía Breve página 24

Interfaces and outputs
The device can be operated in "Remote" mode via an RS 232 or
USB interface using the laboratory software labworldsoft ® .
The RS 232 interface at the back of the device is fitted with a
9-pole SUB-D port which can be connected to a PC. The pins are
assigned serial signals.
Please comply with the system re-
NOTICE
quirements together with the ope-
rating instructions and help sec-
tion included with the software.
USB interface
The Universal Serial Bus (USB) is a serial bus for connecting the
device to the PC. Equipped with USB devices can be connected to
a PC during operation (hot plugging). Connected devices and their
properties are automatically recognized.
Use the USB interface in conjunction with labworldsoft ® for opera-
tion in "Remote" mode and also to update the firmware.
Installation
First, download the latest driver for devices with USB in-terface
from http://www..com//lws/download/usb-driver.zip and install
the driver by running the setup file. Then connect the device
through the USB data cable to the PC.
Serial interface RS 232 (V 24)
Configuration:
• The functions of the interface connections between the de-
vice and the automation system are chosen from the signals
speci-fied in EIA standard RS 232 in accordance with DIN 66
020 Part 1.
• For the electrical characteristics of the interface and the allo-
cation of signal status, standard RS 232 applies in accordance
with DIN 66 259 Part 1.
• Transmission procedure: asynchronous character transmissi-
on in start-stop mode.
• Type of transmission: full duplex.
• Character format: character representation in accordance
with data format in DIN 66 022 for start-stop mode. 1 start
bit; 7 character bits; 1 parity bit (even); 1 stop bit.
• Transmission speed: 9600 bit/s
• Data flow control: none
• Access procedure: data transfer from the device to the com-
puter takes place only at the computer's request
Command syntax and format
The following applies to the command set:
• Commands are generally sent from the computer (Master) to
the stirrer machine (Slave).
• The stirrer machine sends only at the computer's request.
Even fault indications cannot be sent spontaneously from the
device to the computer (automation system).
• Commands are transmitted in capital letters.
• Commands and parameters including successive parameters
are separated by at least one space (Code: hex 0x20).
• Each individual command (incl. parameters and data) and
each response are terminated with Blank CR LF (Code: hex
0x20 hex 0x0d hex 0x20 hex 0x0A) and have a maximum
length of 50 characters.
• The decimal separator in a number is a dot (Code: hex 0x2E).

The above details correspond as far as possible to the recommen-
dations of the NAMUR working party (NAMUR recommendations
for the design of electrical plug connections for analogue and
digital signal transmission on individual items of laboratory control
equipment, rev. 1.1).
The NAMUR commands and the additional specific commands
serve only as low level commands for communication between
the stirrer machine and the PC. With a suitable terminal or com-
munications programme these commands can be transmitted di-
rectly to the stirrer equipment.
The software package, labworldsoft ® , provides a convenient
tool for controlling the equipment and collecting data under MS
Windows, and includes graphical entry features, for motor speed
ramps for example.
The following table summarises the (NAMUR) commands under
-stood by the control equipment.
NAMUR Commands Function
IN_NAME Read device name
IN_PV_3 Read PT 1000 value
IN_PV_66 Read current pressure value
IN_SP_66 Read pressure target value
IN_SP_70 Read hysteresis target value
IN_MODE_66 Read current evacuation mode
IN_ERROR Read error status
OUT_SP_66 Set pressure target value
OUT_SP_70 Set hysteresis value
OUT_MODE_66 Set evacuation mode
START_66 Start evacuation
STOP_66 Stop evacuation
RESET Switch to normal operating mode

Maintenance and cleaning
The device is maintenance-free. It is only subject to the natural
wear and tear of components and their statistical failure rate.
Cleaning
- For cleaning disconnect the mains plug!
- Use only cleaning agents which have been approved by to
clean devices.
These are water (with tenside) and isopropanol.
- Wear protective gloves during cleaning the devices.
- Electrical devices may not be placed in the cleansing agent for
the purpose of cleaning.
- Do not allow moisture to get into the device when cleaning.
- Before using another than the recommended method for
cleaning or decontamination, the user must ascertain with that
this method does not destroy the device.
