VB Script in MP270B, little help needed

userxyz · Mar 14, 2007

Hi

I made 2 I/O fields and I connected Tag_1 and Tag_2

Then I wrote this in Script_1:

Dim Mitsu = Int
Dim S7 = Int
Mitsu = SmartTags("Tag_1")
S7 = SmartTags("Tag_2")
Mitsu = S7

I want the value of Tag_1 connected with the value of Tag_2.

I'm doing this because I have 2 connections on this panel, one to a mitsubishi and one to and S7. So I want a connection between the PLC's of 1 tag via the panel.

But the code doesn't work, for you vb script spcialists, this must be easy ?? I don't know anything about scripting, this is the first I'm writing

greets

script

IN MP370

Step1

Create a tag s7 (internal tag of type UInt)

Also create another tag mitsu of same type

Step2

Go to scripts and make a script named “s72mitsu”

In the name field in the properties of this script type “s72mitsu”

Under type filed select Function

Lastly in parameter field type “s7” and press ADD button

Under script body u just need to write

S72mitsu=s7

Step3

Go to properties of s7 tag

Under event CHANGE VALUE select the script s72mitsu

Step4

In any screen make two IO fields

To one field attach the tag s7 (input)and to other IO filed attach the tag mitsu(output)

You are done

Not sure.

Maybe try to change

Mitsu = S7

to

SmartTags("Tag_1") := S7

edit: Actually it is a good question.
"How to write values to the connected PLC via Scripts".
If manmeetvirdi's code work, then it could be easy.

mitsu

and where do you specify to write to mitsu

JesperMP · Mar 14, 2007

Maybe it can be done without scripts.

With a ChangeValue trigger, just add the function SetValue to Tag_2. Let the target be Tag_1, and the Value Tag_2.

great idea

I'll try it

JesperMP · Mar 14, 2007

By the way.
The HMI must monitor Tag_2 constantly. So you must change the Acquisition Mode from Cyclic on use to Cyclic continous.

Step3(step 3 procedure in last post was incomplete)

Go to properties of s7 tag

Under event CHANGE VALUE select the script s72mitsu

Outputvalue-->mitsu(tag)

s7-->s7 (tag)
