In Jay Electronique solution, the wireless E-Stop is attainable but it’s not a general mobile E-Stop for all the machines in the line. In this solution, the E-Stop control via wireless is predefined on certain radio channel. So the HMI Terminal is only associated to some fixed machines. Actually, two modes are defined in Jay Electronique wireless E-Stop, i.e. Monitoring Diagnostics and manual. The E-Stop button cane be activated in different conditions for these two modes.
