Citect: Displaying IO device comm. Error

[nikhil.warade2]

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.

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.
