What Are The Benefits Of Using Both An Hmi And Plc, As Opposed To Just A Plc? |
|
Answer» The benefits of USING an HMI ALONG with a PLC are substantial. PLCs TEND to be complex, with MANY wires connected to them, making it difficult to find the correct input to manually TOGGLE. With an HMI, the user can toggle PLC's through memory, as opposed to having to re-wire. HMIs also provide a real time view of the system, so if recipe memory in the PLC was to max out, the user could easily wipe its contents without having to disconnect the PLC.
