Prerequisites
This document assumes the following is already installed on the 6110 instrument and the PC:
6110 Instrument
• Operating system version 1.10 or later
• TPA software version 2.11 or later
Note: The above can be verified by selecting CONFIGURATION>Instrument parameters>System information
from the instrument and checking the main board installed versions.
PC
• OPC client software installed and configured following instructions provided by the OPC client
software provider
Overview
OPC (Open Process Control) is a software interface standard that allows Windows PC programs to
communicate with industrial hardware devices. The OPC client software is installed on a PC and
communicates directly with the OPC server installed on the 6110 instrument (as illustrated in
Figure 1).
Figure 1 Ethernet configuration between 6110 instrument and local PC
The OPC server feature allows communication with up to 5 OPC clients at the same time.
Set up the link between server and client
The server is installed on the 6110 instrument and the client on the PC. Follow these instructions to
establish the link between the two.
Note: The PC screen shots illustrated below are from the Softing OPC software. If using software from a different
supplier the screens will differ but the concept is still the same.
1. From the CONFIGURATION menu on the instrument select Communication option and then
press the Ethernet configuration button.
2. Make a note of the instrument ID displayed in the Device name box of this screen, then check
the OPC option at the bottom of the screen.
3. The first time this option is selected, a registration key is required. This can be found on the case
of the Hach-Lange supplied OPC CD-ROM. Enter the registration key in the box provided.
4. After the registration key has been validated, press the information button next to the OPC
checkbox to display the CLSID number as illustrated below. Make a note of this number.
English

5. Start the OPC client application on the PC to display the initial screen.
6. Enter the CLSID number in the <CLSID of the OPC Data Access Server> field followed by the
instrument ID in the <Computer name or address> field. Click on the CLSID number and the
server URL will automatically appear in the URL box.
7. Click on the Add Server button to establish the link between the 6110 instrument and the PC.

English
Note: If communications problems are encountered between the OPC client and server it may be necessary to
adjust the DCOM and/or Firewall configurations. Information on these can be found on the internet or from your
OPC client software supplier.
8. Click on the DA Browse tab to display the data available.
Refer to the documentation for the OPC client software installed for details on accessing the data
available.
OPC items
The OPC protocol identifies the data passed between server and client with a three level hierarchy
called an item. The item may contain data, error messages, warning messages, etc.
To ensure total synchronization between PC and instrument, all modifications that are made to data
elements on the instrument are automatically sent to the client PC as a message item.
The following data items are sent in read-only format from the instrument to the OPC client, and
represent data from the 6110 instrument:
• Package - Data about the package currently selected by the instrument
• Measurement - Data about the last measurement made by the instrument
• Calibration - Data about the current calibration parameters being used by the instrument
Note: No historical data is available from the instrument.
Message items can be sent from the instrument to the OPC client ("Message Out" items) and from
the OPC client to the instrument ("Message In" items).
English

All date fields are formatted according to the ISO 8601 extended format "YYYY-MM-DDThh:mm:ssZ"
where "T" is the Date/Time separator and "Z" signifies "UTC time". An undefined date is sent as
"0000-00-00T00:00:00Z"

"Messages.Message Out.Warnings" item
This output item provides information about any warning(s) associated with the system. A warning
does not prevent the instrument from running a measurement analysis. This is a flag field where the
indicated value is computed by the addition of all active warnings.
The list items are identical to those listed in the corresponding errors table (see "Messages.Message
Out.Errors" item on page 11).
"Messages.Message Out.Message In Last Error" item
This item indicates the last error raised by an incoming OPC message. For example, when a
"Message In.New Package" item (see "Messages.Message In.New Package" item on page 10)
requests setting the package to one that is not defined on the 6110 instrument, the error value will be
"POOR".
Note: In the following table "par_name" represents the parameter name to which the error relates.
Error value Error description
