The Yokogawa small OPC and central control communication can only display 1,000 data points
Thread Content
As the title suggests, it was finally possible to establish communication between the Yokogawa OPC system and the central control system; 640,000 data points can be retrieved. However, when trying to add data in the central control system, only 1,000 valid data points are displayed – any number exceeding 1,000 is shown as invalid. Experts, is this a problem with the central control system or with the Yokogawa system? Yokogawa said that grouping is required. I found the grouping option in VBOPCTEST, but I can’t add it. Could someone with expertise help me?
Does the central control unit also need data grouping? Thousands of data points – it’s a large volume. Just take a look at the key data.
The control room said it’s not possible to form groups; it’s a problem. The project involves over 8,000 elements, and the client needs to see all the data displayed on the screens, which means there are too many communication points
