Unistream 10 Master and V700 slave over rs485

[Aurimas]

Hello all, I am new to unitronics products and software. Maybe anyone has experience with Unistream 10 Master and V700 slave (3 devices as slaves) over rs485 project or something similar.

Any help would be appreciated.

My advice is to mock it up and start working.  When you hit a roadblock post a question here.  CANbus could be used.  As well as the EX-RC1.

There are also example projects that come with your VisiLogic and UniLogic installations that may be of help.

I managed to do Master - Slave over Modbus rs485, next thing I'm interested in is how to have 8 slaves connected to one Master, do I need some kind of device for that or just do a daisy chain thing?

RS485 is Daisy chain, just link them together.

Use shielded cable and ground the shield at one end of each link

A+ to A+ etc .   B- to B- etc.

The UniStream is 1  and each device has its own  ID Number

Baud rate is set to be common to all

 Connect 1 at a time and get it going before adding in the next one.

Be sure to use the terminations  1 at each end,

Hi..I haven't used the Unistream system yet. On the V700 side, that particular model is a bit of an oddball with model-specific initialization commands.Check out the Visilogic help file and monkey-see, monkey-do the comms on the first one. Look at your system bits and system integer values. If you run into specific issues, let me know where the stop point is, I'm in the middle of programming one of my V700's into a basic machine learning platform.
