Hi,

It's my first time when I'm working with Twido PLC, and I have a very strage problem.
Let's say I have such rung:
<pre>
| I0.0 I0.1 Q0.0 |
+-----] [-----] [------()----+
| |


When both inputs are active the output doesn't get active.

Maybe anyone else had this problem and knows how to solve it?

Example:<br>

Thanks in advance.

Please check if you have used the same output in any other part of your logic.

I know this is a stupid question, but are you sure you put the Twido into run mode?

Check to see if the output (Q0.0 and %M41 in your two examples) is also addressed anywhere else in the program. There might be another rung turning the same output off.

Is your configuration correct? If you don't have the hardware configuration correct, the output will not function.

Check the hardware configuration. If it is incorrect, the outputs will not function.

You probably have some Set or Reset instructions using that output. Don´t mix coils and memorized actions.

Take care

When two inputs is high then there should be output. If not, there are two possibilities:

1. Maybe anywhere line is deleted in between output & input

2. Twido PLC may be in stop mode

With regards,

Pls make a note of Serial number of Twido you are using and check with schneider support team, You might require a patch as some cpu version had a problem
