Modbus is a well established protocol that is commonly used and ideally suited
for connecting multiple devices in a commercial/institutional or industrial
environment. This is largely because of its resilience when it comes to
electrical interference. The Rada Digital Faucet products are designed for serial
communications protocols, but can be configured to communicate with a BMS
(Building Management System) using the Modbus protocol. When configured for
Modbus, the product acts as an RTU (Remote Terminal Unit) that is monitored by
the BMS.
The following is a guide for connecting a Rada Digital Faucet product to a BMS
using a Modbus RTU protocol. Please review the Product Manual available at
www.radacontrols.com to familiarize yourself with the product specification and
installation before attempting to connect the BMS.
Sub networks can have up to 31 valves.
Each product requires commissioning via the Rada Digital Faucet App “RADA
AP1” available for Apple iPad. Commissioning must be done at the product
location over a Bluetooth®wireless network so that it can be monitored. All
settings for the products are applied from the App. Each product in a network
will need a unique network address (1 - 31) which is set from the App before the
network is made live. Links to download the “RADA AP1” App and the Guide are
found at www.armstronginternational.com be conducted strictly in accordance
with the information supplied with the disinfectant and with all relevant
Guidelines/Approved Codes of Practice.
