Hello again @JasperJackson,
as we discussed via email, the image 1.7 and latest development version of MervisIDE fixes the problem you have encountered. Another problem occured when reading states of the digital inputs. We discovered a problem in the installation package and issued a new version. To fix your problem, SSH into the PLC and issue these commands:
sudo su
dpkg -P evok-mini pigpio
apt-get update
apt-get clean
apt-get install evok-mini
reboot
For clean image 1.7 you just need to install the fixed evok-mini package.
Martin
