7  Graphic interface – Webserver function
The PLC PL500, in the PL500-335-1AD-WEB variation, provides both a graphical 
interface and the chance to develop synoptics thanks to the integrated runtime 
Movicon 11 CE.
It is possible to access the graphic interface through any 
“VNC client”

the Webserver HTML5 function integrated in Movicon. This last one allows 
you to access the synoptics from any Internet browser or with a specific App, 
available for Android and iOS.

browser.
The PLC PL700 provides both a graphical interface and the chance to develop 
synoptics thanks to the integrated runtime Codesys. It is possible to access the
