<div class="markdown_content"><p>Hi,</p> <p>if you build your own plc based on CODESYS based on an Linux System,<br/> you could install QT on your system (Linux) and then you need to have the targetvisu feature.<br/> Then you have visualisation on your local screen connected to your plc.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Hi,</p> <ol> <li>currently there is a problem on the license server / actvation is not possible<br/> 2 manually start the runtime:<br/> first do a stop (if license time expired on a demo Pi)<br/> you need to:<br/> sudo /etc/init.d/codesyscontrol stop<br/> then<br/> sudo /etc/init.d/codesyscontrol stop</li> </ol> <p>BR <br/> Edwin</p> <p>PS: IF you are updating wheezy / and the kernel by rpi-update you have then 3.18 kernel which have some new features<br/> for example device tree support, which makes some changes in the /boot/config.txt necesarry,<br/> we will try to take all this changes into account with the new 3.5SP6 release next week.</p> <p>For those who can't wait with the new kernel and CODESYS Runtime:<br/> please add to /boot/config.txt </p> <p>dtparam=i2c_arm=on<br/> dtparam=spi=on<br/> dtoverlay=w1-gpio-pullup,pullup=1</p> <p>to have I2C / SPI and 1Wire with the new kernel and CODESYS Runtime</p></div>
