Connecting Unitronixv130 And Daqfactory

Recommended Posts

I am trying to connect Unitronix Vision 130 to DAQ factory via MODBUS TCP protocol. I tried with the OPC server (unOPC) but can not get the tags. In DAQFactory CHANNELS I use UniOPC-MyDevice. MB or MI but can not read variable. I try with MODBUS TCP protocol but also can not read the variable. I try to use SEQUENCER with this code http://www.azeotech.com/board/index.php?/topic/4856-readholdingu16station-starting-address-num-points/#entry16918 .

 

 
Can someone help me with an example? UNITRONIX code?

 

Regards,

Bojan

Does the unOPC OPC server communicate with the device outside of DAQFactory?  Are you sure its communicating?  If the device is Modbus, I would try going direct.  Many devices support only one connection at a time, so you'd have to make sure the OPC server was not running at the same time, then load up either the ModbusTCP sample, or even QuickMod and see if you can get it going.  Note that when the Vision's were first released, there was a bug in the Modbus implementation.  You may want to make sure you have the latest firmware on the PLC too.
