Dear DOJO,
What is the best practice to hide (not want to show) parameter in virtual driver which must be visible in module “Linked Parameter” (“Element connections / Configure /Linked Parameter).
For egc. if we want to use parameter1 in virtual driver for get value from physical driver parameter. We want to use parameter1 only for transferring value for another calculations, but not want to show it on any page. If made parameter1 RTDisplay=false, then it is not visible in Element connection module. If made parameter 1 RTDisplay=true but without position properties, then everything works OK (it is not shown on any pages) but DIS validator report errors. Also, it is possible to define parametar1 displayed on some page, configure Element connections, start virtual driver and after that in virtual driver erase position properties, set RTDisplay=false and upload those changed program again in DMA. There is no DIS Validator error, virtual driver works fine, but is it allowed way?
Thank you.
Hi,
The best way in this case would be to set RTDisplay to true on the parameter, without positions specified. Run the DIS Validator and on the reported issue right-click on it and suppress the error and provide as reason that RTDisplay true is needed because it is used in the element connections -> that reason makes it clear for everyone what the purpose of that parameter is and avoids it being removed by accident in the future.
Nice, thank you!
