HMI slow response

[rajendra.mahajan]

Hi,
On demand how to update tag values from controller (approx. 200 tags) written in script module? The tags used are in sequential order.

If we use always active setting, these tags will be continuously polled and performance of the HMI is slow.

iX panel used is iXT70 and controller is Mitsubishi FX3U PLC

At present we are using Tag.Read() for each tag in the script module

Best regards,

If Tag.Read() is not working, then I'm not aware of another way.

Is there any other way to read block(group) of tags from plc?
This will reduce the time required to fetch tag data than fetching the tag data individually.

There is not a way to do that, but depending on the driver being used, addresses that are next to each other may be grouped together in the background for better performance.

You might be able to use the datatype "String" to read a block of ASCII data, but I have not tested it and the behavior may vary depending on the driver you are using.
