    Refer to individual product manuals for speci�c register maps and descriptions.

    Data registers are 16 bits wide with addresses using the standard MODICON protocol.

    Floating point values use the standard IEEE 32-bit format occupying two contiguous 16 bit registers.

    ASCII values are stored with two characters (bytes) per register in hexadecimal format.

    Coil registers are single bit values which control and indicate the status of a relay; 1 = on, 0 = o�.

    Agrowtek’s intelligent sensors, relays and peristaltic pumps are designed to communicate via the standard industrial MODBUS RTU protocol for PLC and OEM control applications.

    Each device may be assigned an address of 1-247. Address 254 is a universal broadcast address. Addresses may be sent to the address register by MODBUS command, or con�gured using the LX1 USB link with PC software.

    LX1 USB AgrowLINK Agrowtek’s intelligent devices may be connected to the LX1 USB AgrowLINK for �rmware updates, calibration, addressing and testing/manual op- eration.

    Standard drivers automatically install in Windows for the LX1 USB AgrowLINK. MODBUS com- mands may be sent over USB from a terminal or software application. More advanced GrowNET™ commands are also available over the LX1 USB conection.

    USB Connection Requirements: 115,200 baud, 8-N-1

    Connections

    LX2 ModLINK™ LX2 ModLINK™ connects Agrowtek’s intelligent sensors, peristaltic dosing pumps, and control relays equipped with a GrowNET™ RJ45 port to a standard RS-485 serial bus for use with the MODBUS RTU protocol. ModLINK is an MCU-bu�ered bridge between Agrowtek’s high-speed, full duplex GrowNET™ devices connected with RJ45 cables, to a terminal block for integration with PLC systems. 15kV ESD rated RS485 terminals with 70V fault protection to protect against wiring errors and short circuits. LX2 may be con�gured for 19,200 -115,200 baud rates and any serial data format usung the LX1 USB Link and free PC application.

    HX8 GrowNET hubs connect multiple devices to a MODBUS network using only one LX2 ModLINK.

    HX8 hubs supply power to all 8 ports from one power supply to operate sensors and relays from the GrowNET (Ethernet) cable connection for fast, easy installation (pumps require their own power supply.)

    HX8 Hubs are fully bu�ered for excellent signal performance in long distance and distributed applications. Daisy chain hubs as needed for the number of ports required.

    Uses standard RJ45 Ethernet cable for all connections.

    The default serial data format for the LX2 ModLINK interface is: 19,200 baud, 8-N-1.

    Alternate speeds and formats may be con�gured with the LX1 USB AgrowLINK and the cross-over adapter supplied with the LX2 ModLINK.

    Data Format & Speed

    Open the ModLINK utility and set: Device Address = 254 (address must be set to 254 to con�gure the LX2.)

    Con�gure the serial settings according to your master control device, then press the “Set” button.

    “OK” reply con�rms the settings have been successfully con�gured on the LX2.

    The LX1 USB AgrowLINK may be used to con�gure the LX2 ModLINK and set device (slave) addresss of devices.

    Setting Device (Slave) Address

    Download ModLINK Utility

    1. Connect the GrowNET™ device to the USB AgrowLINK with a standard Ethernet cable. 2. Connect the USB AgrowLINK to the PC and allow the drivers to install automatically. If the drivers do not install automatically download and install them Download Driver.

    The slave ID is stored in each device at address register 1 (40001) and can be modi�ed in several ways.

    1. Send a modbus command using the broadcast address (254) to modify the value in register 1. 2. Use the LX1 USB link connected to a device with the AgrowLINK software utility to set the address.

    Device address 254 is a universal broadcast address which can be used to set an address on a device which has an unknown address or has a 0 address. The device to be con�gured must be the only device on the bus when using the broadcast address or con�icts may occur.

    To set a device address of “5”, send the value “5” to register# 1 (40001) using address 254.

    Set Address via Modbus
