Posted 20 May 2015 Is it possible to have the HMI send the active screen number to the PLC (FX3), also perhaps have the PLC switch to a particular screen number? I've been pouring over the manuals but they are as clear as mud. Thanks Steve Share this post Link to post Share on other sites
Posted 21 May 2015 Yes, its very simple. Just set the Screen switching device in the environmental settings. This device can be read by the plc or written to. Just move the number of the screen you want into that register. Share this post Link to post Share on other sites
Posted 21 May 2015 Thanks Delbert, I had already decipherd the manual as you say it's very simple, just for those who may need to know, here's how you get the current active screen number back to the PLC. Share this post Link to post Share on other sites
