INTERNAL/AUTHORIZED SERVICE PROVIDER INFORMATION DO NOT FORWARD TO CUSTOMER
BioTector analyzers are moving to native two-way, full Modbus communication. This enhancement allows access to a complete Modbus register map, including read and read/write registers of reaction results, settings, calibration, and diagnostic information from the analyzer.
-KEY MESSAGE POINTS:
- All B7000 configurations with Modbus RTU or Modbus TCP/IP will begin shipping October 1, 2018 with this new full Modbus capability. The new B7000 part number configurators launched September 1st are equipped with this option.
- All B3500 configurations with Modbus RTU or Modbus TCP/IP will be available Q1 2019 with this new full Modbus capability. New configurators with the new Modbus options will be launched just prior to allow quoting of this option.
- This upgrade replaces previous Modbus, Ethernet, and BioTector Network Control Unit options in the BioTector configurations.
We are excited to announce this enhancement of BioTector communications to allow for full Modbus functionality. Per this change, manuals, specification sheets, tender text, CSI specifications, and datasheets are also changing, and going forward, these new versions should be used. This new feature has several key benefits over the previous Modbus, Ethernet, and BioTector Network Control Unit (BNCU) functionalities.
The previous Modbus and Ethernet capabilities provided up to two measurement results directly or up to six results in multiplex mode. They also provided alarm signals for low reagent, warning, and fault.
Conversely, with the new Modbus RTU and Modbus TCP/IP functionality, the user will have access to a complete register map of information about the analyzer, including reaction results, settings, calibration, and diagnostic information. This communication enhancement significantly improves the remote visibility to the analyzer’s state as well as allows for remote control of the analyzer through Modbus read/write registers.
These new Modbus communication options also replace the BNCU option, which allowed access to monitor and control a BioTector analyzer remotely through a web browser. The BNCU required an internet connection and web browser access. It provided the user with a predefined dashboard to view the analyzers last reaction, reagents status, last fault or warning, and a trend graph. There were also options to program email notifications and create diagnostic reports.
The addition of full Modbus capability allows for the same level of access to the BioTector as the BNCU through a Modbus RTU (two-wire) or Modbus TCP/IP (Ethernet) network. By coupling a BioTector equipped with Modbus and a customer’s SCADA or PLC onsite, the customer will not only have access to the full BioTector Modbus register map, but all other Modbus connected Hach instrumentation as well. They will not need an internet connection or web browser access like with the more limited functionality of the BNCU.
-CALLS TO ACTION FOR THE SALES CHANNEL:
- Assist customers desiring Modbus connectivity by quoting the BioTector with Modbus RTU or Modbus TCP/IP.
- Use the new manuals, CSI specifications, tender texts, and datasheets when referring to BioTector analyzer documentation for new sales.

-TECHNICAL SUPPORT: Frequently Asked Questions
Q. Where can I find the new BioTector Modbus register maps?
A. Please find the B7000 Modbus register maps attached. There is one map for the B7000i and B7000i Dairy and a separate map for the B7000 TN/TP.
Q. Where can I find instructions for using the new BioTector Modbus?
A. Please find the B7000 Modbus instructions attached.
Q. Can an existing analyzer be upgraded to native Modbus?
A. No, we are not offering an option to upgrade existing analyzers in the field to native Modbus.
Q. Are the Modbus register maps the same between the old and new analyzers equipped with Modbus?
A. No, the previous Modbus registers were specific to the Acromag converter being used to convert analog signals from the analyzer to digital Modbus signals. The previous Modbus and Ethernet capabilities provided up to two measurement results directly or up to six results in multiplex mode as well as alarm signals for low reagent, warning, and fault.
Now that BioTector analyzers can be configured with native Modbus, the register maps contain much more comprehensive information about the analyzer, including reaction results, settings, calibration, and diagnostic information.
