Hello experts, Under PCS7 V7.0, using OPC item manager I am able to browse OPC tag from OPC server provided by Moore Procidia, and able tomonitor the tag value (in this case 55.58 for 32 bit floating point IEEE 754 data type). But in WinCC runtimethe reading for this tagalways appears"0". The driver status shows "OK" and the quality value shows "4C". I notice the "tag read" always shows "0". Attached are the screenshots (totally 5 screenshots, but maybe only one is successfully uploaded - if so, will try to upload again by next post) Please help! Thanks in advance hgq AttachmentWinCC Runtime - driver information.zip (257 Downloads) |
