Hi, I want to ask on how to scripting form other window. Which mean that I write a value in other window then call it in other window. An example I write a value in other window and call the value using button to read the value. ---

Is this value only for the client? Or is this a value that other clients will need to read? If this is only for the same client, then you can use a client tag. If this is a value that other clients will need to access, then you can use a regular tag. ---

Actually I used pymodbus communication between ignition and my python script to communicated. Then the value that I wrote is in my modbus tags and I want the ignition read the value from the tags. The value “50” will be store in “state1” and the “UP” button will read the “state1” value. ![1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/2/32af717e06173745e6c03549452f6d1b446a2cff.jpeg) ![2](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/f/cfb8d0a8feea1c9541ad8604e9a0bbfecbd81930.jpeg) ![3](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/f/7f1c90a4d28d509202e230bd6b7c7b50930b8e1f.jpeg) ---

it looks like you are there… The red data indicates an issue. If you click on the arrow next to the state1 tag what does the quality say for that tag? ---

The red meant that I don’t connect with the hardware. Once I connected to the hardware it will be normal. ---

Ok if you have tags in the tag browser, then any window can communicate with it. Or maybe I’m not understanding the issue… ---

It’s alright. This the script that I wrote in ignition for read the value. “line 6”. Did the way I wrote is correct? ![4](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/7/17395a7e0500047c05d7087e7f1c8f16b610d8be.jpeg) ---

What version of Ignition? ---

I used ignition 8.1.14 ---

OK then to write a tag in 8.1.14 take a look at this: [system.tag.writeBlocking - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/system.tag.writeBlocking) To read a tag in 8.1.14 look at this: [system.tag.readBlocking - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/system.tag.readBlocking) Can you post your code with ``` before and after so that we can more easily read it? ---

Alright, I will try to write code using the ignition 8.1.14 way. you meant like this: event.source.background = system.gui.color(0,255,0) system.tag.writeBlocking("[Edge]Indicator Panel/PWM-CBM\_Module 1/module1\_DriveUp", 1) system.tag.readBlocking("[edge]_Rozum_/UnitId 0/state1-state12/state1") ---

I followed your code and no error from ignition. But I don’t have the hardware to see the output. it’s possible execute without the hardware? ---

It should. You should see the tag change value. But a better test is to do it with hardware obviously.
