AcuLink 810 Data Aquisition Server
Chapter 9: Protocols
9.1 Modbus
This chapter outlines to users how to add devices from the AcuLink 810 web interface using
the Modbus protocol.
The AcuLink 810 supports both Modbus RTU and Modbus TCP protocols.
9.1.1 RS485 Devices
The AcuLink 810 gateway supports RS485 serial communication. Users can set up an RS485
connection to the AcuLink with any Accuenergy or third party device. If connecting multiple
devices or 'daisy-chaining' the devices together, ensure that a unique device address (Mod-
bus Slave ID) is configured for each RS485 device. The AcuLink 810 can support up to 32
external RS485 devices.
NOTE: A termination resistor at the end of the RS485 network is optional when daisy-chain-
ing multiple devices. If using a resistor a termination value of 150 ohms can be used.
