<div class="markdown_content"><p><em>Originally created by:</em> Alex_</p> <p>Update:</p> <p>I think I narrowed it down to incorrect physical addressing. I see how the IFM CR0303 controller is addressed, but how would I address to the CR2016 card? It appears that I'm not writing to the controller correctly.</p> <p>I'm more familiar with Allen-Bradley PLC's and addressing I/O (Address identifies the card in the rack and the input/output in that card), Codesys is still brand new to me. I see the %QX0.0 (first output of card) addresses for the master card, but what is the convention for the slave card? %QX<span style="color: underline;">0</span>&lt;=does this zero identify the Node #?) </p> <p>If this is true, would the slave card follow suit with the Correct Node #, for example: 2nd Node=&gt; %QX2.0 (first output on 2nd node)? This is very unclear in the manuals. </p> <p>Again, any help would be greatly appreciated. </p> <p>Thanks in advance.</p> <p>-Alex</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> Alex_</p> <p>Hello,</p> <p>I am working with a CR0303 (Master) and CR2016 (Slave). I have the ladder program written, and have no problems logging in and running the program. Both LED's come on for each controller and blink green at 2kHz as expected. I can force the inputs and outputs on/off within the software via the function blocks in the POU, the ladder itself and the global variables. All the rungs go true when any/all are forced on/off. </p> <p>That being said, I am not able to see any corresponding LED's come on when the I/O are forced on. Naturally the CR0303 does not have status LED's, however the CR2016 does. I cannot figure out how to configure them to respond when forced on. Looking through the appendix of the Device Manual I should be able to configure them but I cannot seem to locate where this takes place inside Codesys. </p> <p>Any help would be greatly appreciated. </p> <p>Thank you.</p> <p>Alex</p></div>
