Does anyone know the criteria/standards that walk you through the process of determining if Emergency Stop buttons need to be hardwired, or if they can just be defined on the PLC HMI?
I have a customer that needs to be perform certain E-Stop actions for their particular process application (specialty chemical industry), but they don't currently know if the buttons need to be hardwired (or if they can just be 'soft' buttons on an HMI).
Any input that you can provide would be greatly appreciated. Thanks in advance!
