  • Keep your online view clean: The hiding attributes
    In the post 'How to use monitoring attributes' I showed how to use the monitoring attributes: attribute 'monitoring' := 'variable' and attribute 'monitoring' := 'call'. With these pragma attributes we can monitor and modify our function blocks properties. This comes however with a small drawback. As the online view now shows your properties and their backing fields your online view gets less clear. In this post I will show how to solve this with the hiding attributes.
