Diver-MOD
Connect to the Diver through industrial Modbus networks. Diver-MOD is a Modbus interface for the Diver dataloggers, and is comform to the Modbus Application Protocol v.1.1b3 specifications.
This module enables to interface Divers in a RS485 network using the Modbus/RTU protocol (Modbus TCP/IP is not supported).
Overview
Modbus systems with Diver-MOD
The Diver-MOD allows you to connect the Diver to your MODBUS system as depicted in the figure on the right. On one end the Diver-MOD is connected to the MODBUS system through the 2-wire RS485 protocol and powered by 5 to 12 Volt. On the other end a Diver cable is attached to connect the Diver-MOD to a Diver. Diver-MOD operates as Slave, and all system communication is initiated by the MODBUS (Master). Maximum 8 Diver-MOD modules can be connected to a MODBUS system.
The maximum Modbus cable length depends on the baud rate, the cable (gauge, capacitance or characteristic impedance), the number of loads on the daisy chain, and the network configuration (2-wire or 4-wire). For a maximum 9600 baud rate and AWG26 (or wider) gauge, the maximum length is 1000 meters.
The maximum length of the cable between the Diver-MOD and the Diver is 300 meters.
