RS232 Serial connection + command to multi-valve

[Mahde]

Hi 

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

You do not have translate your command to ASCII codes.  The Protocol Send block does that for you.

Try writing the PLC program yourself and post your program here.  Then we will look at what you've done and help.

In hyperterminal an invisible carriage return is added.  Try adding that to your Send message-

If that doesn't work change your length to 2 and add a "LF" (0A) as well.
