Modbus PLC Interface

The Modbus PLC Interface is a simplified method of communicating with the Aqua TROLL 500 using the 

Modbus protocol. It reduces programming complexity and allows the user to remove sensors and reinstall 

them in different ports. Please observe the following limitations when using this interface:

•  Only one sensor of any sensor model can be used in the sonde (for example: only one turbidity sensor  

  can be installed).

•  If a parameter is provided by more than one of the installed sensors, the interface will return the first  

  value available.

•  Firmware version 1.71 or later must be installed on the sonde.

For information about the full Modbus capabilities of your sonde, see the Aqua TROLL 500/600 Interface 

Specification at www.in-situ.com/support/type/documentation.

Connect the Twist-Lock termination to the instrument and wire the stripped-and-tinned connection as 

shown below:

1. Install the sensors and turn on the display by holding the instrument vertically.

 

a. Ensure the display turns on and check the LCD to ensure the sensors are working.

2. The setup below is using the instrument's factory default settings. Use WinSitu or VuSitu to reset the 

instrument to

factory defaults if they have been changed.

 

a. Take note of any changes in default units setup.
