Hach-Lange ORBISPHERE 6110 OPC Instruction Manual - Manual (Page 5)

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

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 ).

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.
