I don't understand what function the "connection quality - show" property fulfills I have 2 I/O Fields, one with the property checked and the other without the property checked... The tag to display is the same... In the I/O Field that I do NOT have the "connection quality - show" property checked, it shows its value well in the RT and when changing the value in the PLC it updates well in the RT. In the I/O Field that I have checked, the "connection quality - show" property shows the correct value in the RT but the field is marked as if it were in connection failure... when changing the value of the tag in the plc, the RT is also updated but the field still appears to be offline. When disconnecting the PLC from the network, everything remains the same... the field that is marked continues to show connection failure and the field that has the property marked does not show failure... Can someone tell me how to do so that when there is a communication failure the field shows a warning? Attachment Capturas1.zip (186 Downloads)

This could be helpful to find out the reason for seeing the icon. I would recommend using the OnPropertyQCChanged event of the IO field to get the quality code. You can find the event in the IO field properties under General > Process value > Quality code change. Here is a sample script that reads the 'Value' tag - which should be the tag used as the process value - and writes the quality code to the 'label' text: const tag = Tags("Value"); tag.Read(); Screen.FindItem("label").Text = '0x' + tag.QualityCode.toString(16).toUpperCase(); Please provide the quality code you saw in your test. Kind regards Stefan
