Modbus communication with Hach Particle Counters

Modbus communication with Hach Particle Counters

Hello,

 

I'm trying to communicate with a couple different Hatch Particle Counters.  A model 3413 and a model 3411. 

 

The units have an Ethernet port and I have been given a modbus register map, but unfortunately little other information.

 

Using the modbus library example, I was able to open a TCP port to the unit.  Reading any registers or coils always resulted in a timeout.

 

I received some supplementary information about a 3rd party OPC server that listed modbus communication with this Particle Counter model as only through the USB port.

 

The on-board configuration of the unit shows the modbus port on the Ethernet configuration screen, so I only assumed modbus was possible through Ethernet.

 

I was curious if anyone had successfully communicated with one of these or a similar unit.
