Hi, Ofir..
I'm using the port 3 for the communication. It's a V200-19-R4 expansion, and i set the jumpers in the mode BB .
I made this configuration and the RS485 cable, checking this manual: http://www.unitronics.com/Data/Uploads/communication/Unitronics%20Devices%20and%20RS485.pdf because i'm using a old version of Vision280 .
About the master and the slave, i set both with the same parameters, including also the "com port" (COM 3), "parity" (None), "Standard" (RS485) and "Stop Bits"(1).
I made the 0v connection too, but what do you mean with "the regulators"?

Hi guys. first of all, i'm from portugal, and my english is not so good, but i'll try to explain my problem the best as i can.
I'm new at this world, and i have to do a project for a company.
It's my first contact with Vision280.
What i have to do is something like this:
So, i have to control two water pumps, via Vision280. I need to send, via Modbus, the commands to read and write the values in the variable frequency drives (the model is: Vacon 0010 -3L-0006-4).
I was talking with the Vacon guys and they told me all the parameters that i have to insert in frequency drives to stablish the communication through modbus.
And i was checking your examples and manuals, and i did a little program to read 2 values from one of those frequency drives, but something is wrong with the communication, because i got the errors 4 and 5 at the "error status" in the R.H.R block.
Can someone give me a little help?
Thanks in advance
