Posted 28 Jul 2016 Hi guys, In my current project, I have a number of energy meters (128) communicating on Modnet (TCPIP) with Citect as different IO devices. I have a screen, where I wish to display the communication status of each IO device. If there is an error communicating with a particular I need to associate a tag for displaying the same. Can someone guide me how to accomplish this. Thanks for looking in. Share this post Link to post Share on other sites
Posted 10 Oct 2016 Hi, To find the device state, you can use the cicode function name "IODeviceInfo". Output of this function can be configured to return device RUNNING or OFFLINE state. Regards, Share this post Link to post Share on other sites
