Modbus Addressing
The SV2 Series valve models with intelligence levels of 6 with embedded Modbus RTU open protocol communications can
communicate with an external Modbus master device either directly or through a secondary port of the HMI with the 'Gateway-
Connect to External Systems' selection as explained in the Introduction portion of the
CONNECTIVITY section.
Before attempting external Modbus master connection, each connected valve must be fully individually setup and programmed
including any intelligent features, Modbus addressing, bias resistor setup and baud rates.
This manual provides an overview of connectivity to the valve and an external Modbus master. Detailed wiring, setup and
programming information is provided in the reference documents listed in the previous Connectivity Notes section.
The HMI / PC Tools and the SV2 Series valves support RS-485 Modbus RTU communications with:
• 1 start bit
• 8 data bits
• 1 stop bit
• no parity
Refer to the APPENDIX of this manual for the detailed Modbus addressing information.
CHAPTER 4 : ACCESSORIES, FIELD REPLACEMENTS AND INTELLIGENT
FEATURES
The SV2 Series valves are built on a flexible modular platform, including modular components that could be added and/or
replaced in the field plus several accessories. Additionally, there are intelligent features which can be utilized when certain
accessories are used with the SV2 Series valves. Accessories and field replacement parts include C6097 pressure switches, HMI
or PC programming tools for any intelligent features, Pressure Modules, flanges, replacement electronics and replacement
solenoids. All of these items are detailed in this section of the manual. For further information and/or detailed installation
instructions, refer to the documents noted in each section.
