Sample Taken Signal - BLX Configuration

Modified on 2017/09/05 14:56 by MKR Categorized as QCX BlendExpert Mill V8

For BLX to register a sample correct it has to be connected to a "Sample Taken" Signal. This signal can either come from the Autosampling system or if the site dont have an autosampling system the signal must be made by the sampler;<br /><br />
*either by a physical push button which send a signal that a sample have been taken<br /><br />
*or by a PLC at the sampler registering that there have been taken a sample.<br /><br />
When QCX gets the Sample Taken signal it logs in a sample in the active sample window and then it awaits the analysis.<br /><br />
BLX keeps accounting of the tons of material the sample represents and if the signal <strong>is not</strong> logged in correctly BLX gets the wrong accounting. <br /><br />
<br /><br />
BLX will <strong>not</strong> work correctly if the sample is logged in later than it was physical taken at the sampler. So if a sample was taken by the sampler at f.ex. 15:00 hr it has to physical logged into active samples at that same time! It wil <strong>NOT</strong> work if this sample is registred in active samples at f.ex 15:30 but with the 15:00 hr sample time. Then BLX will get the wrong accounting.<br /><br />
<br /><br />
<strong>So if there are not autosampling system this is how to set up the sample taken signal:</strong><br /><br />
*Go to: <strong>System - Configuration - Point editor</strong><br /><br />
**Browse to right location for the signal : For instance: <strong>BLXMills; PS_line1 - Controller</strong><br /><br />
**Select: <strong>Create new point</strong><br /><br />
**Name: <strong>SampleTaken signal</strong><br /><br />
**Functional Parent: <strong>QCX</strong><br /><br />
**Point Type: BLX point type: <strong>DigitalRead</strong><br /><br />
**Select the IO interface system<br /><br />
**Click: <strong>OK</strong><br /><br />
<br /><br />
Now in the point editor link the newly created point to the right IO adress.<br /><br />
Then open the QCX Lab editor (System --> configuration --> QCX Lab editor)<br /><br />
Under the Lab Samper / Raw Meal sampler: there is a line to enter the sample taken signal. Here browse for the point and insert it. <br /><br />
Now there is a setup so everytime a sample is taken at the sampler there is a sample logged in at Active Samples with the right time and Right production.
