RS232 Serial connection + command to multi-valve

Recommended Posts


I have a multi-valve that can communicate with rs232 by hyper terminal in normal pc.

Iam trying to connect the valve by v570 visio plcs.

I understand from the unitronics examples that i can use send protocol

One comand i can send is : 1go5

This command for example move the valve to port 5.

In hyper terminal after i connect i simply type 1go5 and the valve start moving.

What i shoud write in send protocol FB?

I have to translate the 1go5 to ASCI code before?

Can anybody direct me for this?

Thank you
