Posted 7 Jul 2021 Hi! I'm interested, is it possible to configure a second GOT HMI on an existing machine? The current HMI is on CC-Link IE field communication on a net switch. (It's just an idea for upgrading the production) Share this post Link to post Share on other sites
Posted 7 Jul 2021 There is no reason you cannot have more than one HMI talking to a PLC. Share this post Link to post Share on other sites
Posted 7 Jul 2021 Hi gman1, technically it is no problem to connect several HMIs to one PLC. If necessary, you have to enter another MELSOFT connection in the network settings of the PLC, so that both HMIs can access the controller at the same time. For a good user experience, make sure that the names and messages on both HMIs are the same and that the display of data values on both HMIs is the same (no problem if PLC data registers are used, this is not always the case with internal data registers of the HMI).
