I am working on a project where the PLC (Siemens S7-1200) controlled machined is to be operated behind a glass door. Running Ethernet or power cables is not possible,so I need a mobile wireless HMI panel with a screen size of about 4 to 7 inches. Please suggest me one. Simatic Mobile Panel 277 IWLAN has been phased out and no suitable successor product is now available.
Thanks in advance
