USC B10 TR22 // UAC CB 01RS4_0 // MODBUS STATUS 3 // HAMILTON VisiFerm DO Arc 120

Hello I'm using  USC B10 TR22 with  UAC CB 01RS4_0  as modbus communication dev. I am communicating with HAMILTON VisiFerm DO Arc 120 but the Modbus status is 3 and thus there is no connection. I checked with HAMILTON programmer and the modbus in sensor is working correctly (image 1).

 

I checked with the Logic Analyzers from Saleae and the commands from PLC are "going" but there is no reply from sensor. Is there anything wrong with my program ? (imige 2,3,4,5);

I found the problem but i still dont know how to implement it in Unilogic.

basically i connected the modbus sensor to usb  and i found out that it is very presize in terms of data. 

I need to send something like this 

 

 

Is it possible to achive in unilogic ?

I send this

and dont get any response,

I think this isn't modbus. When you look at the request string you must send, this appears to me that isn't modbus...

You can try to communicate with message composer

modbus requests are like this
